    @ Marian

    Dear Marian

    Thanks for comment I will try to answer your questions.

    1st
    1. Should the input pipe be long until almost reached the bottom of the tank ?
    Ans. yes input pipe should be 2 or 3 inch above at the bottom.

    2. The mixture has to be supplied via input pipe daily ? Can this be let open ? This INLET pipe will be in contact with the oxygen from air, so it is ok ?
    Ans. Yes daily fed is must after feeding you have to close inlet with cap or with other stuff . pipe can be in air there is no effect on gas production

    3. The gas output pipe is fine, i got it how it works and where it will be connected.

    4. The output pipe for the mixture is quite unclear for me. How it works ?
    Ans. output pipe cap only open when you will feeding to digester, outlet pipe use to excrete digester waste.

    In my tank, how should we place it ?
    Ans. your diagram of digester is fine you can make like diagram.

    If it is too low, the mixture will get out.
    I Can not understand this question

    If is too high, the mixture will get air through it and the produced gas will be mixed with O2 and it will not have the desired effect.

    you can also see this link http://paksc.org/pk/biogas-plant-design here is some useful article and videos I hope you will understand

    Hello,

    I am writing you from Romania.
    I am looking to build a biogas plant at home and i have looked at some designs on the Internet.
    Before i start building it, i just wanna get cleared with some questions.
    Can you guys help me to build it ?

    Mainly, i have some 300-500 liters tanks made of iron. I have made a design but i am not very sure o it.

    1. Should the input pipe be long until almost reached the bottom of the tank ?
    2. The mixture has to be supplied via input pipe daily ? Can this be let open ? This INLET pipe will be in contact with the oxygen from air, so it is ok ?
    3. The gas output pipe is fine, i got it how it works and where it will be connected.
    4. The output pipe for the mixture is quite unclear for me. How it works ?
    In my tank, how should we place it ?
    If it is too low, the mixture will get out.
    If is too high, the mixture will get air through it and the produced gas will be mixed with O2 and it will not have the desired effect.

    I have seen some designs, where the digester tank is bigger. The tank has the upper side cut and we can fit a smaller cut tank that acts like a gas collector. I don’t really understand how this works. The mixture is fed through the input pipe, and the mixture gets the upper tank up. In this case, the upper tank, being smaller than the one from bottom it will leave some margins where the mixture will be in contact with the air. Is this ok ? Can you explain it a bit ?

    How is the outlet pipe working in this case ?
    Basically we have the input and output pipe but also we have the area that is in contact with the air. We can feed the mixture through that side that is in contact with the air and when it will overflow it will send the surpuls of mixture out.
    Can you explain a bit ?

    Looking to hear news from you !

    Thank you and best regards From Romania !

    I have really learnt alot about Biogas production from the people of Pakistan.I intend to start my own biogas plant.Here in our country Kenya many people do not know about biogas.I will use the knowledge i have gained to help others.Thank you.

    @Maurice
    yes we have made large one for home use you can visit http://www.paksc.org/pk/our-projects/item/747-small-scale-kitchen-waste-biogas-plant.html
    and I didn’t found any problems with smells or H2S or NH3. The temprature of the digester remain constant in winter because I used cotton around the digester for insulation.

    yes “Ian” you can use fruit peel as digester feedstock but it should be blended

    Tuesday, 08 January 2013 12:40 posted by Ian
    can i use it just using a fruit peels like mango?? please answer

    A great project, well done. Have any of you installed one of these for home use? Any problems with smells or other gas problems H2S or NH3?
    How have you kept the temperature stable?

    the inlet and outlet pipe closed with pipe caps, this caps stops slurry to go back, and gas pressure remain constant.
    Thanks

    hello,
    how you stick the plastic tubing to the tyre tube?? what tool you used? i don’t know how to make sure the gas didn’t go back to the digester?
    im really interested in this experiment, hope you can reply as soon as possible 🙂

    I am a Mechanical Engineering Undergraduate Student in Renewable Energy from Malaysia
    Thank you sharing on how you guys carry out this mini Biogas project
    It really makes me amazed that even teenagers nowadays have brilliant mind
    Keep up the good work!
    Thank you

    hy nice work but i still want to how much gas will produce “quantity of gas?”
    also till how many days the methane produced can be used

    This is very interesting. I am about to work on it,but i didn’t understand the issue of the old tube.
    I would be very grateful if i am fed back.

    Dear Gene thanks you for your attention to safety matters we have idea about the risk of that project , we also mentions it Safety caution in that article.

    methane gas is odorless,colourless how can you assure the safety of people using this kind of gas without asking yourself first what should i do if i have a leaking pipe gas without knowing it because its odourless , colorless and flammable type of gas.your design of simple biogas set up is a good project but not safe for others to try especially for students like your age. although the main focus of your project is using alternative energy you must also consider the safety of others by emphasizing “how can i use this technology with out harming me and others”.whats good with new technology if using it might cause more harm than good.anyway your project is good as for now but dont be discouraged or angry by my comments its just im trying to suggest that you must push forward to make your project not just as a project but a very good one.

    Why do you have 2 pipes in the digester ?
    What is the horizontal pipe for ??

    Just to exit the used up slurry ?

    Many thanks.
    Great project !

    THIS IS YOUR VERY NICE PROJECT, BECAUSE THIS IS A VERY SIMPLE AND A SAFE METHOD TO PRODUCE GAS. I ALSO WANT TO MAKE MORE FANTASTIC PROJECTS AS SUCH KIND. .

    This is an easy & safe way to help reduce the energy crisis in Developing countries, additionally it also stops the cutting of trees, to be used a fuel. Well done for such helpful information.
