kitchen waste to energy 0.5 Ton capacity plant


Introduction: kitchen waste to energy
Add kitchen bio degradable Solid waste to a 5 HP mixer to process the waste before putting it into predigestor tank. The waste is converted in slurry by mixing with water (1:1) in this mixture.
Use of thermophilic microbes for faster degradation of the waste. The growth of thermophiles in the predigestor tank is assured by mixing the waste with hot water and maintaining the temperature in the range of 55-60oC. The hot water supply is from a solar heater. Even one-hour sunlight is sufficient per day to meet the needs of hot water.
After the predigestor tank the slurry enters the main tank where it undergoes mainly anaerobic degra-dation by a consortium of archae-bacteria belonging to Methanococcus group. These bacteria are naturally present in the alimentary canal of ruminant animals (cattle). They produce mainly methane from the cellulosic materials in the slurry.
The undigested lignocellulosic and hemicellulosic materials then are passed on in the settling tank. After about a month high quality manure can be dug out from the settling tanks. There is no odour to the manure at all. The organic contents are high and this can improve the quality of humus in soil, which in turn is responsible for the fertility.
As the gas is generated in the main tank, the dome is slowly lifted up. It reaches a maximum height of 8 feet . This gas is a mixture of methane (70-75%), carbondioxide (10-15%) and water vapours (5-10%). It is taken through GI pipeline to the lamp posts. Drains for condensed water vapour are provided on line. This gas burns with a blue flame and can be used for cooking as well.
The gas generated in this plant is used for gas lights fitted around the plant. The potential use of this gas would be for a canteen. The manure generated is high quality and can be used in fields.
Success of this biogas plant depends a great deal on proper segregation of the kitchen waste. The materials that can pose problems to the efficient running of plant are coconut shells and coir, egg shells, onion peels, bones and plastic pieces. Steel utensils like dishes, spoons etc. are likely to appear in the waste bags from canteens. While bones, shells and utensils can spoil the mixer physically, onion peels, coir and plastic can have detrimental effects on microbial consortium in the predigester and main digestion tanks which could be disastrous for the plant.

Bio Gas from Kitchen waste



Literature Study : Bio Gas from Kitchen waste
The Principle: Biomass in any form is ideal for the Biomethanation concept, which is the central idea of the Biogas plants. Based on thermophilic microorganisms and microbial processes develop the design of the biogas plant. The plant is completely gravity based.
Brief process description: The segregated wet garbage (food waste) is brought to the plant site in bins and containers. It is loaded on a sorting platform and residual plastic, metal; glass and other non-biodegradable items are further segregated. The waste is loaded into a Waste Crusher along with water, which is mounted on the platform. The food waste slurry mixed with hot water is directly charged into the Primary digester.
This digester serves mainly as hydrolysis cum acidification tank for the treatment of suspended solids. For breaking slag compressed air is used for agitation of slurry. Compressed air will also help in increasing aeration since bacteria involved in this tank are aerobic in nature. The tank is designed in such a way that after the system reaches equilibrium in initial 4-5 days, the fresh slurry entering the tank will displace equal amount of digested matter from top into the main digester tank.
Main digester tank serves as a methane fermentation tank and BOD reduction takes place here. The treated overflow from this digester is connected to the manure pits. This manure can be supplied to farmers at the rate of 4-5 Rs. per Kg. Alternatively municipal gardens and local gardens can be assured of regular manure from this biogas plant.
The biogas is collected in a dome (Gas holder) is a drum like structure, fabricated either of mild steel sheets or fibreglass reinforced plastic (FRP). It fits like a cap on the mouth of digester where it is submerged in the water and rests in the ledge, constructed inside the digester for this purpose. The drum collects gas, which is produced from the slurry inside the digester as it gets decomposed and rises upward, being lighter than air. 1" GI piping will be provided up to a distance of 50 m from the Biogas plant. Biogas burners will be provided. The biogas can be used for cooking, heating and power generation purpose.
Cost details, saving and payback period from a biogas plant: The cost details and the savings envisaged from the plant are given in the following table. The life of the plant could be 20-30 years and payback period is 4-5 years.

Feeding of Effluent to USAB Reactor: Anaerobic digestion takes place here. Methane gas is generated because of anaerobic degradation. The top supernatant from the USAB reactor flows by gravity to the aeration tanks inlet. Three reactors are planned. When one reactor is out of operation, calamity flow is the designed flow. One distribution box will distribute the flow into the three reactors.
  1. Bio-gas collection & utilization or Flaring: The gas produced in the UASB reactors is led to the gas holder through a moisture trap and gas flow meter.The outlet of the gas holder is to be branched off in two directions, one going to the generator room for supply to the engines and the other to the gas flaring equipments. The primary purpose of a gas holder is to adjust the difference in the rate of gas production and consumption.The gas engines demand a constant supply of bio gas at a constant pressure. The bio gas holder is designed for a storage of 4 hours of bio gas production normally at a pressure of 40m bar. As bio gas enters or leaves, the holder rises or falls with the help of guide rails. Valves in the gas lines will be operated manually to maintain the gas dome at 90%(Gas flaring level), 80%(Engine level) and 20% (Low levels, where engine as well as flaring will be stopped and the dome will be allowed to rise.).
GAS PRODUCTION & POWER GENERATION:
The gas flowing upward with the liquid will be prevented from escaping with the treated flow by GLSS and beam deflector, which will divert it to the gas collector domes. The gas produced shall be passed through 100 mm dia FRP pipe for individual domes and collected at a common point for each reactor by a common header of 200 mm dia pipe from where it will conveyed to the gas holder for constant flow to the gasomete generator or flaring in open atmosphere at about 6 meter above ground level.

Effluent COD = 1980 Kg
COD removed in a day = 2970 kg
Bio gas produced @ 0.1 cu mtr per kg of COD removed = 297 cu mtr per day.
Capacity of gas holder: The primary purpose of a gas holder is to adjust the difference in the rate of gas production and consumption. As bio gas enters or leaves, the holder rises or falls by guide rails.
Provide a gas holder of 300 cu mtr capacity.
POWER GENERATION:

The bio gas produced in UASB process should be utilized for production of electric power. The amount of electric power generated shall be as under:
Bio Gas production = 297 cu mtr /day
Methane content (65.75%) = 195.28 cu mtr
Calorific value =28.9 MJ/N.cu mtr
Energy content 195.28x28.9x273/(273+30)=5048 MJ/Day
Generator efficiency--- 30%
Electricity generated =0.3x5048x1000000/3600x1000
= 420.66
Electric power generated = 420.66x0.04167=17.5289 kw say17 kw
= 1.25x 17= 21.25 kva.
We can go for a gas engine of capacity 10 KW . If any gas is left , it will be flared or supplied to staff quarters.


NOTE FOR COMPARISION : A 56 mld UASB plant having Inlet COD =400 ppm can safely run a 45 KW gas engine.

IT grad, now you can get industry-ready online

Suresh Elangovan, CEO and managing director, Mindlogicx, who is also a board member at Anna University in Tamil Nadu, said finishing schools have become essential especially in the IT sector. "Since most of the finishing schools are based in the cities and are too expensive, I thought the best way is to go online. This is the only way to reach people across the country, especially in the rural sector. A student in the rural sector cannot come to the city and attend a finishing school."

He says this idea was floated keeping in mind the vision of former President Dr APJ Abdul Kalam [Images] who had said that it was essential to create a knowledge bank.

How it works
Those interested in joining the course would have to pick up a pre-paid scratch card known as Edu Card. Suresh says they have tied up with Reliance [Get Quote] who will be selling the cards. For the IT finishing course, there are two options available -- re-skilling and up-skilling.

Re-skilling involves enhancement of built up skill. It basically finetunes the skill of a candidate. This card is available at Rs 1,500. Up-skilling would involve the teaching of new skills. Suresh says there are various cards available for this course and the pricing is between Rs 499 and Rs 5,000. 

Suresh says for students who are confused as to what they ought to be learning, they could pick up a card for Rs 499 where details of the various course will be available. The student could take a mock test and the results will be available online. Based on his/her performance s/he would decide on what course s/he wants to do.

The scratch card provides a 16-digit number which a candidate needs to use to log in and create an account. Once a candidate logs in, s/he will get the study material online. Suresh says care has been taken to give a classroom feel to the course. Guest lectures will be available online and students could also participate in group discussions sitting at home, he adds.

Considering the fact that internet speeds are not great in rural India, Suresh says the delivery of the package is available at a mere 40 kpbs speed through a dial-up connection also. He says slow connectivity will not be an issue for students taking up this course.

The examinations too will be online, Suresh adds. Prior to taking up the examination, a student gets a chance to test his skills through a meter to help assess one's performance. If a student thinks s/he is ready, then s/he could take the examination.

The number of attempts a student can make would depend on the denomination of the card. A student who has picked up a card for Rs 499 could make up to 50 attempts and this card would be valid for a year. A Rs 1,500 card would enable a student to have 100 attempts while the Rs 5,000 card would give a student 250 attempts.

A student who uses up all the attempts would have to purchase another card, Suresh says. However, it would be better to get through in the minimum number of attempts as it would read well on the bio-data, he adds.

For those students who complete the up-skilling course they would be certified by T�V Rheinland. Suresh says this certificate will enable students get global validity. The certificate will have a seal of authentication by way of a Global Access Code and the same will be made available in the global database of T�V Rheinland. 

The students can connect to the prospective employers by using this unique GAC that vouches for the authenticity of their knowledge base. Suresh says a certificate for those students taking up the re-skilling course will also be provided. However, the certification would be done by Mindlogicx.
 
The commercial launch of the online finishing school is scheduled for the second week of August 2008. Queries are already flowing in and the responses have been best from Maharashtra, Tamil Nadu and Karnataka, informs Suresh. However, he adds that the response has been better from students in the city when compared to the rural areas. "Over the months we will spread awareness regarding this course in the rural areas."

TRYING TO UNDERSTAND HAJJ & ITS RITUALS:

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)
7. Towel, small, big, one each
8. Hawai Sappal
9. Watch
10. Cotton Shirts and pant
11. A sweater
12. A waist Belt
13. Tissue papers
14. Medicines with prescription
15. Mobile phone
16. tayammum earth

The following is a list of items of daily use you should carry with you. They will make your life easier, and your stay in Saudi Arabia more comfortable.


  1. multi-blade pocket knife, can opener, nail clipper, small scissors.
  2. tooth brush, tooth paste, disposable razors, shaving cream, small mirror, comb, toilet paper (2 rolls), napkins, soap (2 cakes), plastic soap dish, small shampoo bottle, deodorant, chapstick, small vaseline, tooth picks.
  3. pocket Quran, tasbeeh,pen, pencil, notebook.
  4. slippers (flip-flops, thongs, chappals), sneakers, folding umbrella, sunglasses (or clip-on sunshades), small flash light with extra batteries, travel alarm clock, elastic eye-glass holder, baseball cap, 10 zippered sandwich bags, 4 garbage bags, plastic spoons, laundry detergent, 6 plastic grocery bags.
  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

You only have to ask for it.

 
All that you desire is just a request away. You only have to ask for it. Children do so with supreme confidence, but as we grow older, we hesitate to ask for anything as we fear rejection.

    A2/O Wastwater Treatment Plant

    Subject: A2/O Wastwater Treatment Plant

    Dear sir,
     
     
     
    anyway we are working in A2/O also.
     
    It is necessary to introduce nitrogen and phosphorus removal processes in the  wastewater treatment plants  to improve the water quality . An A2/O (anaerobic-anoxic-oxic) process using immobilized media is proposed here, as a high-end technology to meet stricter discharge standards when faced with treatment space limitations. Fluidized immobilization media were added to the aerobic reactor to maintain a high concentration of nitrifying bacteria and nitrification rate. The process performs well for removal of nitrogen and phosphorus under the condition of HRT = 8 hr, it was possible to obtain an effluent water quality as follows: T-N<8.0 mg/L; T-P<1.0 mg/L.
     
    Flow chart
                      1.3 Q return from Aerobic
                                      l
      Q In--- Anaerobic--Anoxic---Aerobic--Settling--- Out
                     l
              0.5 Q Return From Settling
     
     
    A2/o process is basically adding of  Anoxic zone between Anaerobic and aerobic .
