HOME BIO GAS PLANT FOR A SMALL FAMILY 1 CUM 30 kg cow dung

 HOME BIOGAS PLANT FOR A SMALL FAMILY 1 CUM OF BIO GAS PER DAY

Gas Volume :
One Cu. Mtr. Bio Gas runs approximately 1 Hour at a time. One can cook three meals per day by using 1 cum Bio Gas Plant.1 cum of biogas is equal to 0.43 kg of LPG.We can use Bio Gas frequently about three times a day with an interval of around 2 to 3 hours.

About 8 kg. of kitchen or poultry waste/ 30 kg cow dung( 3 cows) / 20 kg buffallo dung   is required for 1 cum of raw bio gas.This is equal to one gas cylinders per month

One cow produces an average of 10 kg of wet dung a day, equivalent to approximately 2 kg of dry matter.

It has been demonstrated that gas produced from the dung gobar of at least three cows(30kg)  is sufficient to replace about 75 percent of the fuel wood normally used by a family of six people (Dalibard, 1995).

The gas generated will have 60 to 70% methane, 5 to 10% water vapour (moisture) and the balance will be Carbon-di-oxide.
Gas coming out of the plant can be used in the kitchen with the help of biogas stove while the slurry coming out from the outlet can be used as manure. 



30 kg cow dung bio gas plant giving raw bio gas 1 CUM
An one thousand liter capacity Digestion tank will be sufficient for a small household for daily cooking purpose.
1000 liter water tank sintex or eqvt (Fixed dome biogas digester) , inlet pipe, outlet pipe, gas pipe(10 Feet length) , gas control valve and user manual: TOTAL COST  INR 25,000/=Ex Delhi, GST included. (Transport and packaging extra)

How it works for KITCHEN WASTE :

The main digester is initially fed with fresh cow dung slurry so that slurry comes out from the slurry outlet pipe. The ratio of dung and water should be 1:1 Subsequently, cattle dung is not needed. Now wait for biogas production to start in the newly installed plant. It may take 2-3 days for the first production of gas.

As gas starts producing, one can start feeding the plant daily with  kitchen / vegetable waste in a small quantity and increase it to the recommended quantity after one week.. The ratio of kitchen waste and water should be 1:1.This will facilitate easy flow of waste through inlet  into  the  bio-methanization  plant.  The  value  of    pH  of  the  kitchen  waste  should  be ideally kept  at 7 for optimum production of biogas. Make a slurry of lime by adding one kg lime with 10 liter of water and add it into the digester chamber to make pH 7. Check with pH paper whether the pH is 7 or not regularly.

LOCATION:  Always in a sunny area where temperature is high (30 degree) and as near to kitchen as possible so that gas pipe length is less.

OPERATING COST : The operating cost of Bio Gas plant is very less.  All what required for 1 Cu. Mtr Bio Gas plant is  5 to 6 Kg of Kitchen waste / on dry weight basis. Break even period is approximately 5 to 6 years if Gas is used for cooking application

ALL ABOUT ENVO BIO GAS PLANT

ALL ABOUT ENVO BIO GAS PLANT

ONLINE BIO GAS CALCULATOR 






POST NUMBER :08   Date : 02/05/2004
BIO GAS PLANT PROCESS DESCRIPTION:
FLOW CHART: CRUSHER(less than 7mm particle size)----thermophilic Aerobic digester(Temp 55 degree C  )---Mesophilic Anaerobic Digester(37 Degree C )---Manure Pit
Biotechnology process
stage one : hydrolysis by hydrolytic bactaria, conversion of extracellular molecules
stage two : thermophilic fermentation based on carbohydrates
stage three : synthesis of volatile fatty acids by acetogenic bacteria
stage four : synthesis of methane by methanogenic organisms



The Principle:

Add bio degradable Solid waste  into predigestor tank. 
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 anaerobic tank where it undergoes mainly anaerobic degra-dation by a consortium of archae-bacteria belonging to Methanococcus group.  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. Earth worm can be introduced to settling tank to speedup the process.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.The manure generated is high quality and can be used in fields.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.

As the gas is generated in the main tank, the dome is slowly lifted up. 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 gas purification unit. 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 purified gas can be fed to bio fuel electric generator to produce electricity. Gas can be bottled and used to run vehicles.

Decentralised treatment options introduced in new rules.

The earlier rules relied on costly centralised facilities for treating and disposing municipal wastes while approximately 50 per cent of it can be easily turned into compost at the local level. Thus, the draft rules have made the much-needed provision for providing incentives to decentralised waste treatment facilities. 


Considering an average garbage generation per capita per day as 0.450 Kg, we can assume a total garbage generation for a population of 100,000 as 45,000 Kg per day

Proven on wide range of wastes and feedstocks including
  • Livestock and agricultural wastes
  • Biomass
  • Sewage and industrial sludges
  • MSW and catering wastes
  • Food industry wastes
  • Vegetable market waste
  • Restaurant Waste
  • Farm House/Cattle manure waste
  • Slaughter House/Tannery waste
  • Presumed waste
Suitable locations for installation of plant

Hotel premises, army/big establishment canteens (private/ government), residential schools/colleges, housing colonies, religious places / temple trusts, hospitals, hotels, sewage treatment plants, villages, etc.


POWER GENERATION: Bio Gas production = 100 cu mtr /day for 0.5 ton of waste
Methane content (65.75%) = 65.75 cu mtr
Calorific value =28.9 MJ/N.cu mtr
Energy content 65.75x28.9x273/(273+30)=1712 MJ/Day
Generator efficiency--- 30%
Electricity generated =0.3x1712x1000000/3600x1000
= 142.66
Electric power generated = 142.66x0.04167=5.944 kw say 6 kw
= 1.25x 6= 7.5 kva.
We can go for a gas engine of capacity 5 KW . If any gas is left , it will be flared or supplied to staff quarters

Multiply the number of animals by biogas production number...
Example: 600 hogs x 720 m3 biogas / hog / yr = 432000 m3 biogas / year

Multiply the result by the numbers below for cogeneration of electricity and heat...

____________ x 1.7 kWh/ m3 biogas = _________ kWh of electricity per year
____________ x 7.7 MJ/ m3 biogas = _________ MJ of heat per year

Multiply the result by the numbers below for heat production using boiler....
____________ x 15 MJ/ m3 biogas = _________ MJ of heat per year

PHILOSOPHY BEHIND ENVO PROJECTS



PHILOSOPHY BEHIND ENVO PROJECTS

Saleem Asraf Syed Imdaadullah, Founder, Syed Envo Protect (I) Pvt Ltd in the year 1994 & ENVO PROJECTS in the year 2001https://yourstory.com/2009/07/saleem-asraf-syed-imdaadullah-founder-syed-envo-protect-i-pvt-ltd/


ITS NOT POSSIBLE TO FOLLOW ALL THE THINGS THAT OUR PROPHET (Peace be upon him PBUH) HAD DONE, HE IS MODEL FOR ALL PEOPLE IN THIS WORLD.

When I was 10-12 yrs old, i heard Maulana Madani (Senior) RA say that if somebody follows just one sunnah steadfastly throughout his life thats sufficient for him. And pray for me that I can do something for the betterment of this world before I die.... Otherwise there is no meaning of my existence in this world. Doctors are making peoples health better...engineers are making living conditions better.... Alims are making spiritual lives better.

The philosophy behind my work in environmental engineering

NOW HAVE I DONE SOMETHING OR STILL DONT HAVE ANY GOAL IN LIFE.no, I have found in Quran majeed myself that the world is a gift from Allah and nobody has the right to destroy it… .So we don't have any right in making our rivers into drain (read yamuna river,bhorolu river), polluting our air with our car exhaust, littering the greens with solid waste…. I am trying my best in this regard …after forming ENVO.

PREAMBLE OF ENVO

Nature is a gift to us . No individual or organisation has the right dto utilise its resources in such a way that damage or inconvenience is caused  to  people of society . we all have a social responsibility to protect and preserve a clean and green environment. The goale of profit maximisation and customer satisfaction should be surbordinate to the social need and responsibilities. The present concern has been brought about by the health of humans, living being, tree , structures, monuments and all other things.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.


We cant be all rounder like our Prophet (PBUH),but atleast we can excel in one field and serve humnanity as he did.
May Allah accepts my hard work and bestow his blessings on me and forgive me for the major and minor SINS I make in every steps

My own DREAM---"ENVO" and to have its presence in every state of India. (Your time is limited, so don't waste it living someone else's life. Don't let the noise of others' opinions drown out your own inner voice.have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.

 My Passion: My work. of water treatment, to clean the world gifted by god of the mess humans created.  ( Don't lose faith. I'm convinced that the only thing that kept me going was that I loved what I did. You've got to find what you love. And that is as true for your work as it is for your lovers. Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven't found it yet, keep looking. Don't settle. As with all matters of the heart, you'll know when you find it. And, like any great relationship, it just gets better and better as the years roll on. So keep looking until you find it. Don't settle.)

There is still a lot to learn, I try to learn from everybody and atleast one new thing every day : Stay Hungry. Stay Foolish


The World Only Cares About What It Can Get from You.



Change your attitude towards life. Do not look for perfection and CONTROL in everything in life. I understood that my livelihood (RIZQ)  cant be  taken away by  anyone.  Put your  best  efforts in what you do and than leave the result to ALLAH. I have plan but Allahs plan is much much better than mine. I have firm belief in ALLAH.  

During this journey many people came and left me. I thank all of them for their contribution for my growth. They are destined to be with me for that particular period. This is Allah’s plan.

Always sleep with a clean heart. I know many of us get wronged throughout the day or have gotten wronged in the past. Forgive. Not only forgive, but forgive and forget. Dont even hold a grudge against that person in your heart. Keep your heart completely pure.Forgive brothers and sisters before you sleep each night. this is one of the practices of the greatest people ever to live and this is how we will reach those highest levels of spirituality.

Forgiveness is good for your own well being, its about giving yourself permission to let go of the painful past. Forgiveness is not something we do for that particular toxic person,it is something we do for ourselves so we can move on to a better future.We forgive,not because that toxic person deserves it,but because we deserve peace, for a pure heart.
Read quran ,Sura 24:22 , sura 2:263 , sura3:133-134  , sura7:199, sura 15:85, sura 45:14

Ending this article with a hadith

Narrated by Abdullah ibn Amr, Prophet Muhammad (PBUH) stated:"Show mercy and you shall be shown mercy.Forgive others and you shall be forgiven by Allah."(Musnad Ahmad)

LOVE HUMANITY IRRESPECTIVE OF RELIGION, LOVE ANIMALS, TREES AND ALL OF GODS CREATIONS. IF YOU CAN NOT LOVE AND ADMIRE GODS CREATION, HOW CAN YOU THINK ABOUT ADMIRING THE GREATNESS OF GOD.
