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
