QURAN AND ENVIRONMENT



Please read this web site ECO MUSLIMS---10 Quran Verses On The Environment And Do-able Action Plans
Preservation of Water:Another way of ending poverty is to provide clean water where it's needed. This doesn't have to be a burdensome task. Ask your friends/family to chip in £5 for a community well abroad, your home country perhaps. Tell people to reuse their plastic bottles and donate the cost (£1) to your well-fundraising. Save water in your own homes by fixing leaky taps and request that the masjid caps water usage to limit wastage.

Water is a huge life-providing theme in the Qur'an. God talks about how He creates life through water then sustains it by streams, the rains, rivers and oceans that are homes for so many creatures.In the Qur'an, God uses the analogy of life and death for Muslims to recognise the value of water. Prophet Muhammad, peace be upon him, said that one day people will wage war over rivers of gold. He was talking about water. We have taps that fill our basins with gold, but we cannot afford overflows while people wait for the rains. Third-world countries in desert climates are counting on us to give the cost of our water to them.

By starting something simple like a well-fundraiser you kickstart a chain reaction that will motivate others to do the same. People will call your mosque a Green Mosque for following the prophetic Eco-Wudhuand preserving water. Whomever receives your well/water-pump will be able to plant crops, fruits and trees for generations. 
As water is another natural creation, Muslims believe it belongs to God and nobody can monopolise it. Water is for sharing and there is enough water for all.

it is important to be clear that the answers to the following questions reflect the views of the American Muslim scholars that ING has worked with. In other words, we do not speak for or on behalf of all Muslims. In most cases, however, the views of these scholars probably reflect the views of the majority of Sunni Muslims in the U.S. and worldwide.
 https://ing.org/top-100-frequently-asked-questions-about-muslims-and-their-faith/

102. How does Islam view science?

There are numerous verses in the Qur’an that reference scientific phenomena, including discussions of astronomy, geography, biology, and other aspects of nature and the universe. The Qur’an includes, for instance, a detailed description of the different stages that the embryo goes through in the womb, as well as descriptions of the creation of the earth and of the interaction between fresh and salt water.
These repeated Qur’anic references to nature and injunctions to seek knowledge helped create a fruitful environment for science in Islamic history when during the “Golden Age of Islam” in the Middle Ages, Muslims were in the forefront of such fields as mathematics, astronomy, physics, chemistry, botany, zoology, and medicine. Unfortunately, the economic and political decline of the Muslim world in later centuries brought about a decline in scientific and technological endeavor until recent decades.
However, today, many American Muslims and Muslims worldwide work in science-based professions such as medicine, dentistry, and various fields of engineering, and many are leaders in their fields.

104. What is Islam’s view of the environment and the importance of protecting it?

There are hundreds of verses throughout the Qur’an that describe the wonders of creation and nature and call upon humankind to reflect on them as signs of God. Humans are described as stewards over this earth (as is the case in Jewish and Christian scripture), entrusted with its oversight. There are also numerous Qur’anic as well as prophetic injunctions to avoid waste, excess, and harm to other forms of creation. A prophetic saying forbids wasting water, even when washing in a river. Living a balanced, moderate lifestyle is an important Islamic principle advocated by most Muslim scholars that applies to all aspects of life, including care of the earth and all of creation.

It was repeatedly mentioned in the Qur'an: Forbidding from spoiling the earth after Allah (Exalted and Almighty) has created it suitable and well prepared for the successive human generations. It announced that Allah does not like spoiling or those who spoil in life, this includes spoiling environment, polluting it or being aggressive with it. Also it is forbidden to abuse it in any way that would make it deviate from the purpose of Allah created it for. This would be like showing ingratitude to Allah, that would cause vengeance from Allah, and becomes like a warning to those who perpetrated this, that severe penalty will almost come upon them as what happened before to the `Aad and the Thamud and those who came after them.
"Who did transgress beyond bounds in the land (in the disobedience of Allah) and made therein much mischief. So your Lord poured on them different kinds of severe torment. Surely your Lord is Ever-Watchful." (89:11-14) Islam urges its followers to have great concern for everything created by Allah, for it is part and parcel of "submission to Allah" to show reverence to all what the Almighty Allah created.
Elaborating more on this, we cite the following:

The Islamic attitude towards the environment that surrounds humanity is not merely restricted to the presence of Allah everywhere but also to the following dimensions:

By submitting to Allah, Islam establishes the bedrock of the relationship between finite, mortal human beings and the infinite Divine, the secular and the sacred. This relationship cannot be understood without first realising the meaning of the "submission" that the "created" should concede in his relationship with the Creator.

Humans have to accept that they are created beings who act as the "agents" of Allah on earth. These agents are creative in their own way but they are not Allah. Humans, however, will become closer to the sacred by operating according to Allah's instructions. The Prophet (peace and blessings be upon him) in a Hadith Qudsi (Divine Hadith), quotes Allah as saying: "When a worshipper moves closer to me by good virtues and voluntary acts of worship (nawafil), I will be his hearing by which he can hear, I will be his eyes by which he can see, I will be his hand by which he can act, and his feet by which he can walk. If he asks Me [to give him] I will give him what he wants, and if he asks for protection I will protect him." (Al-`Asqalani, 1959: 11, 341)

Islam, as a way of life, expects human beings to conserve the environment for several reasons which may be summarized as follows:

1- The environment, is Allah's creation. The creation of this earth and all its natural resources is a sign of His wisdom, mercy, power and His other attributes and therefore serves to develop human awareness and understanding of this creator. (Ar-Ra`d, 13: 2-4; 21:79)

2- Muslims should seek to protect and preserve the environment because by so doing they protect Allah's creatures which pray to Him and praise Him. Humankind might not be able to understand how these creatures praise Allah but this does not mean that they do not do so, Allah says: (The seven heavens and the earth, and all beings therein, declare His glory: There is not a thing but celebrates His praise, and yet ye understand not how they declare His Glory!) (Al-Israa' 17: 44)

3- The environment contains Allah's creatures which the Muslim scholars consider to also deserve protection.

4- Also among the reasons why Islam seeks to protect and preserve the environment is that Islam, as a way of life, is established on the concept of good (khayr). Therefore it is expected that Islam will protect the environment once it is understood that such protection is good by itself. The Qur'an states: (He whoso do good an atom's weight will see it. And whoso do ill an atom's weight will see it.) (Az-Zalzalah 99: 7-8)

In Islam, humans are expected to protect the environment since no other creature is able to perform this task. Humans are the only being that Allah has "entrusted" with the responsibility of looking after the earth. This trusteeship is seen by Islam to be so onerous and burdensome that no other creature would 'accept' it. Allah says: (Lo! We offered the trust unto the heavens and the earth and the hills, but they shrank from bearing it and were afraid of it and man assumed it Lo! he is a tyrant and fool.) (Al-Ahzab 33: 72)

In Islam the relationship between humankind and the environment is part of social existence, an existence based on the fact that everything on earth worships the same God. This worship is not merely ritual practice, since rituals are simply the symbolic human manifestation of submission to Allah. The actual devotions are actions, which can be practiced by all the creatures of earth sharing the planet with the human race. Moreover humans are responsible for the welfare and sustenance of the other citizens of this global environment. The Qur'an contains many verses that can be referred to for guidance in this respect. The following verse 21 of the second surah of the Qur'an, is one example:

(O people! Worship your Lord, Who hath created you and those before you, so that you may ward off (evil). Who hath appointed the earth a resting-place for you, and the sky a canopy; and causeth water to pour down from the sky, thereby producing fruits as food for you. And do not set up rivals to Allah when ye know (better).) (Al-Baqarah 2: 21-22)

The word in this verse which is translated as "may ward off evil" is in Arabic tattaqun. It enjoins piety and awareness which is accompanied by an appreciation of the surrounding environment. In this verse, the Qur'an speaks directly to all groups of people, whether believers, or not. It attempts to mobilize people to the importance of "worshipping Allah" as a symbol and a way of life that enjoins justice and equity in handling the system created by Him.

This system has been placed under human responsibility, to be cared for and not misused as can be concluded by returning to verse 22 ofsurat al-Baqarah. The word lakum (for you) in the phrase "created for you" contains the message that the earth is not for one generation but for every generation, past, present and future and that would include humans as well as other creatures on this earth. Accordingly, rivers, minerals are the property of all. This should be distributed fairly and justly especially when it happens to be owned collectively like the Rivers Tigris and Euphrates

 Pollution is one form of corruption ("fasal" in Arabic) mentioned in the Glorious Quran eight times. Counting the derivations of the word "fasal" mentioned elsewhere in the Quran raises the number to 49. "Fasal" involves physical corruption like disrupting the environmental phenomena and the contents of the universe (water, soil, food) by foolish human interference in the natural balance created by Allah the Almighty, Who did so wisely, perfectly and infallibly to fit the life of all creatures.

Water pollution in general means polluting water streams, wells, rivers, seas, rain and underground water in such a way that makes it unfit for man, animals, plants, or the sea and ocean creatures. Air pollution involves the discharge of gases, smoke and fumes (the solid, liquid and gaseous forms of matter) into the air surrounding living creatures, and the change of its natural composition. This leads ultimately to the unsuitability of the habitat, contrary to what Allah willed for His creatures. Physiological, economic and biological damages are, in fact, devastating to man, animals, plants and other creatures. 
The corrupters of the earth, whether those who deny God, practice injustice or go against the universal laws, are referred to by the following Quranic verses.
"There is the type of man whose speech about this world's life may dazzle thee, and he calls The God (Allah) to witness about what is in his heart: yet is he the most contentious of enemies? When he turns his back, his aim everywhere is to spread mischief through the earth and destroy crops and cattle. But Allah loves not mischief" (Al-Baqarah: verses 204 and 205)
An incidence occurred prior to these verses being revealed. A man named Al-Akhnas Ibn Shuriq came to the Prophet Muhammad (peace be upon him) to embrace Islam, but as he turned to leave, he happened to pass by a pasture and grazing animals. He set it alight and killed the cattle. The verses were sent down as a sign of Divine disapproval.
This incident recurs over history on a wider scale involving millions of people throughout the earth. The natural wealth deposited by Allah for the benefit of mankind has been spoiled. Selfishness and aggression has overcome mankind, as they have become corrupters of earth, the surrounding atmosphere and neighboring outer space.

MEAT PROCESSING WASTE WATER TREATMENT LATEST TECH MBBR


Source: http://www.esemag.com/0300/waterlink.html
WASTE WATER TREATMENT: MBBR - MOVING BED BIOFILM REACTOR TECHNOLOGY
The MBBR is a biological aerobic degradation of organic pollutants. The process utilizes millions of tiny, polyethylene biofilm elements that provide a high surface area as a home for a vast, highly active bacteria culture. This fixed film process features a flexible reactor design, the ability to handle load increases without the need for extra tankage, and remains stable under large load variations, including temperature, strength or pH. Like the activated sludge process, the MBBR process utilizes the whole volume of an open tank. Unlike an activated sludge reactor, it does not require sludge return to operate effectively. In MBBR , addition of media quantity and Air Quantity is the Key Factor.
The original wastewater treatment system consisted of a chemical pre-treatment system, followed by an anaerobic system, which in turn was followed by an activated sludge process. with high chemical and operating costs





MBBR system replaced the chemical pre-treatment system. MBBRs were installed between the equalization tank (EQ) and the activated sludge system. Total reactor volume of the MBBRs is designed for different hydraulic retention time for different types of waste water at average flows and than checked against peak flows. Essentially nutrient levels and DO levels are the only control points for the system.

Effluent from the MBBR is sent to a dissolved air flotation unit, which removes 70-90% of the solids generated, prior to being discharged to the activated sludge system.

The MBBR reactors reduced the incoming organic load from an average soluble BOD by 50-70% . This reduction allowed the activated sludge process to treat the ammonia-nitrogen within the wastewater in a more efficient and effective manner, allowing a higher volume of treated water to be discharged to drain.


The initial MBBR biofilm unit process shaves the loadings peaks and any toxic inhibition effects while removing 50 to 70 percent of the incoming BOD. This pretreatment achieves 2 to 3 times increased capacity compared to a traditional activated sludge process while also being more compact. Furthermore, the MBBR process improves activated sludge characteristics making the activated sludge stage more inherently stable with a waste sludge that is easier to dewater.

The elements provide a large protected surface area for the biofilm and optimal conditions for the bacteria culture to grow and thrive.
The biofilm that is created around each carrier element protects the bacterial cultures from operating excursions to yield a very robust
system for those industrial facilities loaded with process fluctuations. The biofilm also provides a more stable "home" for the bacteria
to grow, so there is less space required compared to other biological systems and far less controls.
An MBBR can be designed for a new facility to remove BOD/COD from wastewater streams or for nitrogen removal.
Existing activated sludge plants can be upgraded to achieve nitrogen and phosphorus removal or higher BOD/COD capacity .

        • No Sludge Return


        Compact

        • Small Footprint
        • Low Capital Cost













        DETAILED DESIGN & ENGINEERING




        • Media Retention
        • To retain the media within the reator, a stainless steel wedgewire sieve is used. The vigorous action of the moving
      • bed continually scours the surface of the sieve eliminating the need for any maintenance.







        • Aeration Grid
        • A stainless steel grid mounted at the bottom of the reactor is engineered with perforations. The grid is connected to high efficiency
        blowers.. The aeration grid produces a medium bubble which provides the necessary mixing and maintains the dissolved oxygen
        to ~3 ppm.

        The bacterial cultures digest the soluble organics, gradually mature, and slough from the media. The cultures form a natural floc
        which can be easily separated from the water with the DAF unit. In this case and others, no chemical coagulant or polymer were
        necessary to achieve < 10 ppm TSS and over 90% BOD removal.

        RO PLANT START UP MANUAL

        RO Plant Start-Up

        On start up, the inlet valve should open prior to the initiation of the high-pressure pump, to completely fill the system with low pressure water (<100 psi [< 7 Bars]). This "soft start" will prevent hydraulic shock at start-up. Pre-treatment chemical addition should begin at this time (making sure the chemicals are not over-injected). The high-pressure pump should then be started and the system slowly bought on-line, up to design permeate flow.

        If starting up after a period of shutdown, flush the permeate to drain for 30 minutes to remove residual preservation chemicals. Produced water permeate can be used when it meets the quality requirement of downstream processes.

        determinatin of optimum alum dose


        COAGULANT DOSAGE IN A WATER TREATMENT PLANT
        INTRODUCTION
        The main difficulty is to determine the optimum coagulant dosage related
        to the influent of raw water. Excessive coagulant overdosing leads to increased treatment costs and public health concerns, while underdosing leads to a failure to meet the water quality targets and less efficient
        operation of the water treatment plant.
        Manual methods mainly include jar testing
        .
        Jar testing involves taking a raw water sample and applying different quantities of coagulant to each sample. After a short period of time each sample is assessed for water quality and the dosage that produces the optimal result is used as a set point.
        Operators change the dose and make a new jar test if the quality of treated water changes.


        OBJECTIVES


        To conduct jar test on a natural surface water in order to estimate an optimum dosage of aluminum sulfate or ferric sulfate for the removal of suspended matter , To observe the rate of floc formation and sedimentation.
        The dose of coagulant which gives the best floc is the optimum dose of coagulants.


        PROCEDURE

        A. DETERMINE OF OPTIMUM COAGULANT DOSAGE
        1. Collect 20 to 50 liters of a natural surface water. Analyze the water for pH, turbidity, color after filtration, and alkalinity.
        2. Alternatively, make up a synthetic water sample for testing. Record both the water temperature and ambient air temperature.
        3. Calculate the amount of alkalinity required to react with the maximum dosage of aluminum or ferric sulfate. If necessary, augment the natural alkalinity by the addition of 0.1 N Na2CO3 so that the alkalinity will be at least 0.5 meq/l (25 mg/l as CaCO3).
        4. Measure exact 1 liter of water into each jar test reactor. Prepare portions of the aluminum or ferric sulfate solution which will yield 10 to 50 mg/l as Al2O3 or Fe2O3 when added to the sample aliquots.
        5. Mix at 50 rpm to ensure water is completely mixed.
        6. Measure chemical volumes to achieve desired dose in each reactor.
        7. Increase mixing speed to 250 rpm. Add the chemicals to each reactor near the vortex. All reactor should be dosed at the same time.
        8. Rapid mix for 1 min.
        9. Reduce mixing to 60 rpm for 9 min.; Observe the reactors at 3 min. intervals to detect the formation of flocs. Reduce mixing to 25 rpm for 4 min.; Reduce mixing to 10 rpm for 2 min.
        10. Turn off mixers and allow particles to settle for 20 min.
          Measure the turbidity or color, alkalinity, and pH of the liquid in each jar by sampling at the top, taking care not to disturb the sediment in sampling. Measure the depth of sludge in the beaker.
        B DETERMINATION OF OPTIMUM pH Repeat the jar test of Part A using the observed optimum dosage of ferric sulfate but adjusting sample pH to 6, 7, 8, and 9 with NaOH or H2SO4 prior to adding coagulant.
        Measure final pH, turbidity or color of the supernatant of each sample. Measure the depth of sludge in the beaker.
        Plot turbidity or color versus pH.

         

        EFFECT OF MIXING (AGGREGATION KINETICS)

        Prepare identical (optimum) coagulant dosages for all six beakers.
        Use the same rapid mix as before but vary the time of slow mix at 30 rpm. Use 5, 10, 15, 20, 30, and 45 minutes for the six jars respectively. Terminate mixing by carefully lifting the paddle from the beaker at appropriate time.
        Allow 30 minutes for settling.
        Measure the color or turbidity and pH of the supernatant in each beaker.

         

        APPARATUS

        Jar test apparatus and beakers
        Magnetic stirrer plus magnetic stirring bars
        Spectrophotometer or color comparator
        Turbidimeter
        pH meter
        Assorted measurement pipettes (1, 5, 10 ml) and volumetric pipettes to 50 ml
        Burette
        Glass or plastic funnels
        Ringstands and rings

         

        MATERIALS

        Aluminum sulfate solution, 1 g/l or ferric sulfate solution, 1 g/l
        H2SO4, 2 liters each, 5 x 10-2 M, 10-2 M
        NaOH,, 1 liter, 10-1 M
        Sodium carbonate, 1 liter each, 5 x 10-2 M, 10-2 M
        Indicators: methyl orange, phenolphthalein
        Synthetic water sample: Add suspended matter with a kaolin, montmorillonite, illite, or bentonite clay and/or the color with extract from boiled leaves or with instant coffee to raw water. Turbidity might be increased to about 40 turbidity units and color to about 80 color units (Clay suspension sample should be mixed for 3 days).
        Buffer solution
        Whatman #1 filter paper

        REPORT

        Prepare tables which facilitate comparisons of coagulant dosages with alkalinity, pH, color, turbidity, and other changes observed. Plot the inverse of turbidity and color versus coagulant dosage as part of the analysis. Plot turbidity versus coagulant dose at different settling times to determine the influence of floc formation and settling characteristics on the selection of coagulant dosage.
        Comment on the differences between coagulation with iron and aluminum salts. Define the pH ranges over which each salt should result in effective coagulation.
        Determine the rate of aggregation for a particular coagulant dose and pH by plotting the reciprocal of the turbidity versus time. (This would represent a second order reaction with respect to turbidity). Also plot the natural log of the reciprocal turbidity (representing a first order reaction) versus time. Determine which gives the best straight line fit of the data and determine the slope.

        ITS A BIO GAS PLANT FROM SOLID WASTE

        ----- Original Message -----
        Sent: Sunday, September 14, 2008 2:42 PM
        Subject: ITS A GAS BIO GAS


        San Antonio in the United States could become the first city to draw all its energy requirements from methane gas generated from the city's water treatment system through recycling 14,000 tonnes of biosolids in sewage annually. The methane source includes human waste that, if left untreated and unutilised, would only pollute soil and water.

        Treating bio-waste, however, could generate an average of 1.5 million cubic feet of gas a day - enough to fill 1,250 tanker trucks daily - according to the system's chief operating officer. A by-product of human and organic waste, methane is the chief component of natural gas that can fuel generators, power plants and furnaces.

        Closer home, gobar gas - natural gas obtained from methane released by cattle waste - as a green alternative to diesel and other fossil fuels has been taken up seriously, particularly in rural households. However, a lack of adequate hygiene is a constraint because the gas formation - in the large containers filled with gobar - makes the drum's lid rise, and there is spillage all around the plant. So, in India gobar gas plants are fertile breeding grounds for mosquitoes and other pests. But this is not an insurmountable problem. Gobar gas plants could be expanded and diversified to include energy extraction from all kinds of biomass and the gas so produced could fuel power stations - as San Antonio proposes to do - and with improved sanitation, the experiment could yield good results for several Indian cities.

        As a renewable resource, biomass - either from plants, agriculture and forestry residues, animal or human waste - is biodegradable and so is far more eco-friendly than petroleum-derived fuels. And they are relatively easier to source and process, unlike the sophisticated instruments and know-how required to extract oil or refine coal. Ethanol derived from biofuels has a very high octane rating. It might deliver less energy than gasoline, but by blending about 10 per cent ethanol and petrol or diesel together, a feasible balance is achieved with no perceptible effect on fuel economy.

        America's space agency NASA is sponsoring a joint project to turn human waste into a power source for spaceships using a process that could also produce other chemicals that can be used on board. Instead of turning up our noses at the idea of recycling human waste and other biosolids in sewage, it would be worthwhile to explore fully and exploit the immense potential hidden in what we routinely regard as being useless.

        biogas from sewage

        Processing sewage sludge is becoming ever faster as scientists optimise the digestion stages. Now German engineers have developed a high-rate processing plant that generates biogas from sewage in under five days.
        The Fraunhofer Institute for Interfacial Engineering and Biotechnology has been testing its new digestion process in Heidelberg's municipal sewage plant for the past year. Engineers are delighted by the speed and efficiency of the new procedure, with biogas being produced in five days compared with typical processing times of 20 to 30 days. The digestor also operates at a much smaller volume of four litres compared with the usual 60 litres.

        "We have combined an excellent biological process with excellent biochemical engineering," Professor Walter Trösch from the Fraunhofer Institute told edie. "Of the electricity generated from the biogas produced, only a third is used in the process, leaving two-thirds to be sold to the grid or diverted to other areas of the plant." Thus the city of Heidelberg runs off its own sewage.

        The new method has the added advantage of reducing the organic content of sewage by 50 to 60% compared with an average 40% in normal decomposition, resulting in fewer residues to dispose of. But although some processing plants could be updated to incorporate the new procedure, for older plants in Germany the cost of conversion is too high. "Old-fashioned plants would need to be re-built, so their conversion is not yet possible," says Professor Trösch.

        Adapting UASB technology for sewage treatment


        Adapting UASB technology for sewage treatment in Palestine and Jordan [research article]


        March 3, 2008 · No Comments


        High rate anaerobic technologies offer cost-effective solutions for "sewage" treatment in the temperate climate of Palestine and Jordan. However, local sewage characteristics demand amendments to the conventional UASB [upflow anaerobic sludge blanket] reactor design. A solution is found in a parallel operating digester unit that stabilises incoming solids and enriches the UASB sludge bed with methanogenic activity. The digester operational conditions were assessed by operating eight CSTRs [continuous stirred tank reactors] fed with primary sludge. The results showed a high degree of sludge stabilization in the parallel digesters at SRTs [ solids retention times] 10 and 15 days at process temperatures of 35 and 25°C, respectively. The technical feasibility of the UASB-digester combination was demonstrated by continuous flow pilot-scale experiments. A pilot UASB reactor was operated for 81 days at 6 hours HRT [hydraulic retention time] and 15°C and was fed with raw domestic sewage. This period was subsequently followed by an 83 day operation period incorporating a parallel digester unit, which was operated at 35°C. The UASB-digester combination achieved removal efficiencies of total, suspended, colloidal and dissolved CODs of respectively 66, 87, 44 and 30%. Preliminary model calculations indicated that a total reactor volume of the UASB-digester system corresponding to 8.6 hours HRT might suffice for sewage treatment in Palestine. [author abstract]

        In vessel composting (IVC)

        Introduction:

        In vessel composting (IVC) is a managed process in which biodegradable waste is broken down by naturally occurring microorganism with oxygen to produce a stabilized residue called COMPOST.

         

        Inputs:

        Biodegradable Municipal waste (BMW), Agriculture waste, Food processing waste.

        Process:

        Waste is collected and brought to the site where it is first sorted out and shredded to a consistant size. It is than put inside a closed reactor where the composting process is speeded up through the management of water, air and heat. This process is typically takes between 7 to 21 days. The material is than subject to another screening to remove any trace of metals and goes through a further maturation period of upto 10 weeks in a shed. It can than be used as compost or soil conditioner

         

        OUTPUT:

        One Ton of BMW will produce approx. 500 KG of compost.

         

         

         

        In-vessel composting is an industrial form of composting biodegradable waste that occurs in enclosed reactors. These generally consist of metal tanks or concrete bunkers in which air flow and temperature can be controlled. In-vessel composting can also refer to aerated static pile composting with the addition of removable covers that enclose the piles.

        Offensive odours are caused by excess nitrogen or moisture. This may be controlled with a higher carbon to nitrogen ratio or increased aeration by ventilation, mixing, or by using a coarser grade of carbon material. Insects may be controlled by keeping the bin enclosed with the minimum size vents necessary for adequate air exchange. Insects outside the bin enter through the vents and tend to stay inside where the food is. A relatively dry layer of carbon material on top of the compost filters odors and, given adequate ventilation, maintains a moisture gradient that helps keep insects inside where the moisture is.

        An in-vessel composting apparatus for continuous processing of food waste into bulk composting material and liquid compost tea, comprising: an insulated apparatus enclosure, a rotable horizontal drum with an input end having an axial input port and an output end having a relatively larger axial discharge port, said drum divided in length by interior partitions into at least first, second and final chambers, each said partition having an axial port by which adjacent said chambers are connected, a compost tea holding tank, means for shredding and inserting said food waste into said first chamber, means for draining and collecting excess fluid from said first chamber, means for passing remaining said food waste in incremental amounts from said first chamber to said second chamber and from said second chamber as bulk composting material into said final chamber, means for permitting low pressure outgassing from said drum, means for measuring temperature in said second chamber, means for incrementally rotating said drum about its axis, means for exchanging air in said drum for outside air, means for containing a batch volume of said excess fluid at elevated temperature for a predetermined holding period, means for percolating said batch volume of excess fluid into said final chamber and out of said final chamber as compost tea into said compost tea holding tank, and an operator station and a controller, said controller communicating with said means for shredding and inserting, said means for incrementally rotating said drum, said means for measuring temperature, said means for exchanging air, and said operator station, said means for shredding and inserting comprising an input hopper connecting to a multi-toothed rotary shredding mechanism connecting to an auger and chute assembly connecting to said axial input port of said input end of said drum, said axial ports being of sequentially larger diameter from said input port to said discharge port, said chambers further comprising interior structure for tumbling contents during rotation, said structure oriented parallel to said axis of said drum, said means for incrementally rotating said drum comprising a base frame with drum supports and drum support rollers upon which said drum rests, and a motorized drum drive system comprising a motor and gearbox attached to said base frame and coupled to said drum by at least one endless belt, said means for exchanging air in said drum for outside air comprising an exhaust fan and duct, said duct connecting to said drum in the vicinity of said input end.

        Operation & Control

        Before the biodegradable organic waste is loaded into the composting tunnel it must be shredded and provided with the correct level of moisture.

        The control of the Composting Process is based on two parameters – the oxygen level and the lowest temperature in the composting waste.

        Both these parameters are monitored by the PLC continuously. Each is kept within the operator preset ranges of oxygen level and compost temperature by increasing/decreasing the compost blower speed and admitting fresh air into the compost blower suction duct.

        To assist in providing a flexible control system each compost blower speed may be varied.

        The speed of each Biofilter blower may also be varied to maintain the required headspace pressure within the tunnel. This is under PLC control and completely automatic once set up.

        The control of the plant must rely upon instrumentation to detect conditions throughout the plant.

        In-compost temperature monitoring devices are installed at 8 positions along the length of each composting tunnel, plus in the inlet and exhaust ducts for each composting blower, the outlet of each biofilter blower, and the scrubber outlets.

        Oxygen level monitoring is provided in the roof of each tunnel.

        In each tunnel the pressure in the air space above the compost is monitored and compared with atmospheric air pressure. If the difference exceeds maximum process limits an actuated butterfly valve is automatically opened to atmosphere so that the pressure in the tunnel may remain within the pre-set range. An excessive pressure differential could cause damage to the tunnel doors.

        Design & Build

        This plant was constructed for Scottish Water to a design by Enviros Consulting of Shrewsbury. It is designed to compost 20,000 tonnes of class 3 waste per year.

        The composting plant structure is made up of 4 adjacent tunnels each of which is 25 metres long, 5.3 metres wide, and 5.3 metres high. These tunnels are constructed in reinforced concrete. The roofs are also in reinforced concrete. Each composting tunnel is filled by front loader through the full width and length, and to the required batch height. Each composting tunnel may be operated independently.

        The air to each tunnel is supplied through a series of ducts cast into the floor, the air emerging into the compost mass through an array of cast-in plastic nozzles.

        A centrifugal blower is provided for each tunnel. This blower may provide up to 8000 m3/hour of air into the underfloor aeration system.

        The suction side of the blower is connected to the airspace above the composting material so that the composting blower acts to continuously re-circulate the same mass of air through the compost. Fresh air is provided by a branch pipe on the suction side of the composting blower. Control of the fresh air inlet is effected using a modulating square damper in the branch pipe.

        A second centrifugal blower (3000 m3/hr capacity) is provided for each tunnel to draw off exhaust air displaced by any fresh air introduced into the system.

        These four exhaust blowers discharge into two air ducts which lead into two proprietary Scrubbers — designed, manufactured and installed by Forbes of Norfolk. The Scrubbers act to remove ammonia and particulates from the airflow and to ensure that its humidity remains high. The Scrubbers also cool the airflow. This ensures that the air outflow from the Scrubbers may be successfully deodorised by the bacteria living on the media within the Biofilter tunnels.

        The whole of the Biofilter Blower airflow therefore passes through the Scrubbers and the Biofilters, and is then exhausted to atmosphere.

        The Biofilter consist of 2 adjacent rooms — constructed in pre-cast concrete sections - which contain permeable media upon which de-odourising bacteria are grown.

        All above-ground air ducting was fabricated in polypropylene pipe (SDR 33) using the butt fusion process, and incorporating various flanged connections to facilitate disassembly. The discharge duct from each Biofilter blower (into the Scrubber) is in round stainless steel ducting, flanged to suit. The manifold connecting each Composting Blower discharge to the four cast-in re-circulating air pipes per tunnel is also fabricated in stainless steel.

        Household waste from UK dumped in India

        Household waste from UK dumped in India

        LONDON: Household waste collected weekly across Britain for recycling is 
        being shipped and dumped in India, according to an investigation by 
        ITVs 'Tonight programme'.

        As part of country's efforts to go green and improve the environment, UK 
        councils ask households to carefully separate waste into different 
        categories: plastics, metal, paper and glass so that they all can be 
        recycled.

        But, according to the investigation, they were shipped to India on the 
        waste black market, which is cheaper. It costs up to 148 pounds to recycle 
        a tonne of rubbish once it is separated but only 40 pounds to ship it to 
        India.

        The investigation found that a receipt put into a paper recycling bin in 
        Essex turned up at the top of a stinking rubbish mount in Tamil Nadu. It 
        was traced to the Walton-on-the-Naze home of Geoff Moore.

        His receipt for CDs was found by investigators from ITV's 'Tonight' 
        programme at a sprawling rubbish tip in Tamil Nadu. They also found juice 
        cartons, British newspapers, Walkers crisp packets, UK school reports and 
        plastic bags.

        All UK councils are required to recycle. But after householders separate 
        their rubbish and bin workers collect it, councils pass it on to waste 
        firms, who in turn use subcontractors. They are under no obligation to 
        reveal what they actually do with it.

        European Union law bans sending waste abroad for dumping but allows it to 
        go overseas if it has already been separated and provided that it is 
        actually recycled, according to the Sunday Mirror.

        The Environment Agency promised to investigate the matter.

        Paul Bettison of the Local Government Authority Environment Board called 
        for a change in the law and said "if a contractor refuses to reveal where 
        materials are being sold it can undermine the whole process."

        hajj advisory



        NOTE FROM COMPILER:

              THE INTENTION OF THIS POST IS TO SHARE INFORMATION FOR THE BENEFIT OF ALL PEOPLE.PLEASE SHARE IT WITH YOUR RELATIVES AND FRIENDS.MAYBE IT WILL HELP SOMEBODY.ITS "SADAQA JAARIYAH" TO SPREAD KNOWLEDGE THAT HELPS OTHERS.IT IS NEVER MEANT FOR SHOW OFF WHICH IS A BIG SIN..

        How to do tamattu  haj

        PRIMARY AIM OF HAJJ :

        To remain at all times focused on the primary aim of his Hajj: to plead to
        The Almighty to forgive his sins and to bless him with The Straight Path for
        the remainder of his life. it is the starting point of one's commitment to
        cast away one's bad ways and to begin afresh a new Allah-centred life.

        A. Some useful information (Advisory) for hajj:

        1. Medicines: Take medical prescription alongwith you. Most pilgrims will
        suffer from one or more of the following: sore throat, coughing, frequent
        sneezing, runny nose , fever, leg cramp , foot sore. Bring enough supplies of over the counter medicine on advice of your personal doctor with his rubber stamped prescription containing his registration number
        . This will reduce the need to make frequent trips to the makkah medina indian
        pharmacy and also lower your out of pocket expenses.
        2. Take multivitamins daily as you may not be eating a balanced diet
        there. You may want to consider a diet of bottled water, jamjam water, dates and fruits as this will reduce the need to go to the toilet frequently. This diet may also help to keep you more alert and not make you feel 'sleepy'. You will thus
        have more time to worship.
        3. The Hajj pilgrimage involves a lot of walking. If you don't go for daily
        walks at home, begin it well before your journey to The Holy Land. This will
        reduce the likelihood of getting muscle pulls and cramps. The tawaf, sa'ee,
        and the frequent daily walks to The Mosque will help to improve your health.
        Do not stop this habit of walking when you return home. You must to be in
        the best of health to concentrate fully on your worship wherever you are.
        4. You are never more than a foot from another pilgrim when you are in
        Mecca during the peak period of the pilgrimage. Cover your nose and mouth
        with a mask when you leave your hotel/apartment to reduce the likelihood of
        infection. You can get a good quality washable mask at the pharmacies
        there.
        5. If you wear glasses, bring along an extra pair, preferably one with a
        plastic frame. The likelihood of your glasses falling down and being stepped
        on by sudden movements of the crowd are high. As an additional cover, bring
        along your glass prescriptions as well. There are optical shops near The
        Mosque. It is common for those wearing glasses to remove it and place it in 
        front before starting their prayer. Never do this in both mosques. The
        likelihood of your glasses being stepped on by others is 99%.
        6. Flatulence (passing of wind) is an important cause of the loss of wudu. In
        the crowd packed Holy Mosques, this can be a big problem. Avoid or reduce
        the intake of food that contribute to this problem. If this is a serious
        problem for you, consult your doctor. Both herbal and other medications
        [antacid antiflatulent] are now available to reduce the occurrence of
        flatulence.
        7. It is very important that the pilgrim wears his identification tag at all
        times he/she is out of his place of accommodation
        B. Location map of Kaba and medina in the brain
        If I am standing facing the door of the Kaba, On my left its Hazre Aswad ,
        than on my right its Hateem and on my back its makame ibraheem and
        further behind its zam zam.
        Tawaf starts from the black stone hazre aswad. During the peak Haj period, DO NOT attempt to kiss The Black Stone hazre aswad.
        We used to sit in mataaf facing the kaaba door till all our companions gather at the same place. Similarly we used to gather near the iron gate near jannatul baqi in medina till all our companions gather. Only after that we used to go to our home together. 

        Other Items You should Take Along:
        1. A 20 Inch suitcase with name, address, passport no, cover no written outside.
        2. A small carry bag
        3. A warm bed sheet
        4. A small bag for Stones to be collected at muzdalifa to throw stone at satan at mina
        5. Small Torch
        6. Two sets of Ihram ( one towel set and one Cotton set)

        5. towels (2 large, 2 small), musalla (i.e. prayer rug), one heavy sheet, inflatable pillow.
        Common medicines required are :
        Imodium(Stomach problem), Paracetamol(Fever), Ibuprofen (Pain Releif),Neosporine ointment,Vaselin (For feet), Multivitamines and your regular medicines as given by your doctor.

        Medication during Hajj

        Gastrointestinal and respiratory infections are very common during Hajj . Carry certain medicines with you for use later.

        PREVENTIVE ANTIBIOTICS: Ask your doctor to prescribe a broad-spectrum antibiotic to be taken prophylactically (i.e., as a preventive measure) throughout your stay in Saudi Arabia. This writer's (saleem) doctor prescribed 250 mg of the antibiotic CIPLOX250 to be taken daily once. I never contracted any disease during my stay there but all my team members suffered this and that.
        Some people were prescribed AMOXICILLIN in place of CIPLOX250 by doctors and pharmacists with good results. 
        1. Take Medicines with prescription
        Carry a reasonable supply of over-the-counter drugs such as :
        1.Ibuprofen (for pain)
        2. TYLENOL PM (as a sleep-aid)
        3. BENGAY, ASPERCREME (for muscular pain)
        4. IMMODIUM (for diarrhoea)
        5. EMETROL (for nausea)
        6. Anti Allergic like Cetzine10, Allegra120
        7.Paracetamol (Fever),
        8. COUGH Syrup
        9. MULTI-VITAMINS,
        10. ANTI-BACTERIAL CREAM (for cuts) Neosporine ointment, Vaselin(dry weather)
        11.BAND-AIDS, Cotton, Dettol

        b. Take multivitamins daily as you may not be eating a balanced diet

        c. You may want to consider a diet of  jum jum water, dates and fruits as this
        will reduce the need to go to the toilet frequently. This diet may also
        help to keep you more alert and not make you feel 'sleepy'. You will thus
        have more time to worship.

        Tawaf (Arabic: طواف) is one of the principal rites of the pilgrimage and refers to circumambulating or walking in circles around the Kaaba in an anti-clockwise motion. Seven complete circuits, with each one starting and ending at the hazre aswad the black stone, constitute one Tawaf.
        Sa'ee is an Arabic word which means ritual walking or formal procedure defined in Pilgrimage. It is the back and forth movement between the hills of Safa and Marwah in Makkah. It is an integral part of the Hajj and Umrah in Islam.Thus the walk begins at Safa and ends at MarwahStarting from Safa one should walk to Marwah and this constitutes one walk, from Marwah back to Safa the second and so on up to seven walks finally ending at Marwah.
        YOU WILL BE IN IHRAM DURING STAY AT MINA, ARAFAT, MUDALIFAH. Learn dos and donts when in Ihraam.There is no problem in taking insulin injection during ihram by diabetic patients as it is not among the forbidden things in ihram.
        For detailed description of hajj pls read this article https://islamqa.info/en/31822

        7th zil hajj ;
        Take a bath(ghusl) , WEAR IHRAM, pray two rakats sunnat and make niyyat for hajj tamattu. Say Talbiyah (" labbaik....)
        Go to kaaba , do TAWAF & SAYEE. If you do sayee now,no need to do sayee in tawaf e ziyarat ( FARZ TAWAAF on 10th zul hajj ) .

        8 th zul hajj : Spend the day & night at Mina. Pray five salaats.
        we were sent to arafah from mina on the nite itself .

        9 th zul hajj: Day of Arafah : From dhuhr to asr, "STAND UP" for prayers & pleadings at Arafah maidan ( inside tent ). "Arafah is Hajj". Keep this in mind.

        After sun set at arafat ,we went to mujdalifah and stayed the night there under open sky ( no tent ) . its too cold at night but we cant wear anything as we are in ihraam  , we collected 70 pebbles at mujdalifah. 

        10th zul hajj: day of Qurbaani :

        on the morning of 10 th zilhaj , we offer fazr prayer at mujdalifah and immidiately move to mina with the stones in hand to stone the big satan.

        Five things are to be done serially one after another on the 10th day. You cant break the series atall. or you will have to offer a dum ( a sheep ).

        the series is as follows :

        1. Stone the big satan ( only the big satan, not the other two) with seven pebbles . you can throw pebbles on behalf of other persons also who cant throw themselves.
        2. Do the qurbani ( if you personally want to do the jawah of the sheep than u will have to go to makkah to do so, since we gave the duty of doing the qurbani to a saudi govt. bank , we did not went to makkah, instead we rested at our tent in mina and waited for the qurbaani time to be over )
        3.  Shave off hair ( After the qurbaani time is over )
        4. Took off Ihraam ( After shaving )
        5. immidietly went to makkah to do tawaf e ziyarat ( FARZ TAWAAF ) . In tawaf e ziyarat , we have not done Ramal, Izteba, and sayee.
        6. After farz tawaf ,we came back to mina to stay the night at mina tents.

         11 th zul hajj . you stone the three satans , each of them with seven stones after dhuhr prayer ( not before noon ). stay at mina.

         12 th zul hajj . you stone the three satans , each of them with seven stones after dhuhr prayer ( not before noon ). And now, you must leave mina boundary line before maghrib to makkah. if you are in Mina after sunset  , you will have to stay one another day at mina (13 th zul hajj also) and stone the three satans...he he he....and nobody wants to live in mina for another night.

        You have now completed Hajj Tamattu Minus Tawaf Al Wada  ( Farewell Tawaf )

        BEFORE U LEAVE FOR INDIA :

        Before coming back to Home (India) , you do Tawaf al wada, no sayee .

        With this last act, by the grace of almighty Allah your tamattu haj is complete.

         ++++++++++++++++++++++++++++++++++++++++++++

        MY OWN HAJ EXPERIENCE IN 2008

        ( 03.11.2008) we boarded a  plane at Guwahati Airport (The first direct flight from Guwahati to Jeddah Non Stop) noon time and reached jeddah at maghrib. And travelled by bus to makkah and at isha time we offered our FIRST prayer in life DIRECTLY infront of Kaaba. 
        I just cant describe the feeling here. Seeing is only believing. Go for it man when you are young and energetic.




        Here is one of my haj experience that you may find interesting and informative 

        ...
        at makkah u find barbers to shave off your hairs easily. so many of them are there....shouting at you...kom here kom here...

        But on the 10th zulhijjah, at mina, you will not find barbers easily. and you cant shave yourself or your male relative cant shave you if he has not shaved his hair .We want to take off Ihraam fast , so, i searched and searched frantically but could not find any.

        nobody there take chances with unknown people . But I asked one boy whether he will shave me, he said yah yah, why not. and now listen how he shaved me. i gave him my razor. he opened the razor set and took out the blade. holding the blade by hand he shaved me in 10 minutes flat. and my head was red here and there with cuts.

        my mom was not worried about the cuts , she was worried about the unknown boy and probable infection. i Told mom that I carried the blade from Delhi. (MY OWN BLADE)

        After that , i shaved my father and took almost one hour to shave him, isko dekh kar shamim bhai dar gaye and he took a round of the tents at mina aur shamim bhai ko kisi ne kar diyaa ganja,

        Summery of the story : Take your own blade with u when u go there. and dont take unnecessary risks.












        I think the book "HOJOLOI OLAOK " in assamese compiled by syed sayeedur rahman is the most easy to follow and step by step haj guide book I have ever found. email: sayeedbinjamal@gmail.com
