Step 8:

Completed unit. I have removed the gas pipe, so that the joints will get cured without any stress:

Wait for a day or two before feeding the system, allowing all joints to get cured and become leak-proof.

Initially, cow-dung mixed with water will be fed in to the system, which will start the gas formation process. Subsequently, food waste, decomposable organic material and kitchen waste will be diluted with water and used to feed the system. The gas holder will rise along the guide pipes based on the amount of gas produced. We can add some weight on top of the gas holder to increase the gas pressure. When we feed the system, the excess digested slurry will fall out through the outlet pipe, which can be collected, diluted and used as organic manure.

Initial production of gas will consist of oxygen, methane, carbon di oxide and some other gases and will not burn. These gases can be released to the atmosphere by opening the ball valve at least three / four times.

Subsequent gas will consist of about 70 to 80 percent methane and the rest carbon di oxide, which can be used in a single bio-gas burning stove or a Bunsen burner.

Total cost of this proto-type system is about one thousand Indian Rupees (about 20 dollars)

This is a basic prototype of a Bio-gas system using the food waste, decomposable organic material and kitchen waste to produce gas. An one thousand litre capacity Digestion tank will be sufficient for a small household for daily cooking purpose. The bigger commercial models provide a water seal between the digestion tank and gas holder tank.

Sir,<br>Is it a floating type digester?
yes, it is a floating type digester
Sir, May I ask you why did you prefer building floating type over fixed dome type?
<p>Fixed dome types are for larger Biogas plants having more than 3 cum capacity. With plastic buckets / drums and water tanks, floating type is the easiest to construct and maintain</p>

Namaskaram Antoniraj garu,<br> Iam intrested in constructing small biogas plant for my home purpose. Can you plz let me know how much it costs and procedure to construct it by myself. My mail ID is chvenu16@gmail.com. <br> Thanks a ton for sharing your knowledge.
Hello chvenuchary,<br><br>You can see my other instructable on building a medium Biogas plant for domestic use here...<br><br>http://www.instructables.com/id/Constructing-a-Medium-Sized-Biogas-Plant-Using-Kit/<br><br>In this I have used 750 ltr tank as digester and 500 ltr tank as Gas holder. This setup may cost you around 12000 Rupees excluding the Stove

<p>Hello Sir,</p><p>I appreciate the effort you have spent to come out with this great ideas and innovations of biogas production. I would like to use one. Could you please send me the terms and conditions in order to secure one. Below is my email address.</p><p>sirlordy@gmail.com</p><p>Thank you.</p>
you can construct one yourself... please see attached file sent to your mail
Thanks for the files sent. I will study it and consult when needed.<br><br>Thanks again.<br>
Pl give detail of single as well as community based biog as plant.can we fill in small cylinders. dr_riteshgarg@yahoo.com
For a single home use, please see my other instructable here on a medium sized Biogas Plant...<br><br>http://www.instructables.com/id/Constructing-a-Medium-Sized-Biogas-Plant-Using-Kit/<br><br>For community use, please go through the construction manual sent to your mail.<br><br>Biogas can be filled in cylinders after purification but needs huge infrastructure. t can be easily filled in car tyre tubes
<p>Dear Antoniraj Sir,</p><p>The idea was really innovative and the explanation is also easily understandable. I would like to make such simple and effective low cost bio gas plant using food waste and cow dung.Will you please suggest me in terms of capacity,volume requirement, solid waste requirement and cost as well. If you email me I will be more than happy.</p><p>My email id is gurusunil50@gmail.com</p><p>Many thanks again.</p>
please go through the files sent to your mail. you have to calculate the cost based on the material available at your place

<p>I am interested in using this in my home and saw one that was made outside and placed under ground with a pipe going to the house for the gas. It had places to dump the different type of waste from above ground into it. Can you help me with the engineering and layout in design work, so I can recreate this. Thanks so much...</p>
<p>Please go through the construction details of such type Biogas plants sent to your mail</p>
<p>antoniraj, I am also very interested in building the system that dparrish2 requested. Would you please send me instructions also? </p><p></p><p></p><p>mmandistar@yahoo.com</p>
