Biogas of cow dung

[Bouba]

I would like to know the details of the sizing of a biodigester with cow dung (quantity of water and dung for example)

Thank you

[Christophe]

Uh, it's a bit light as a question, isn't it?

You want to reason in what direction? Quantity of dung or electrical power required?

[Bouba]

I want to know the volume of the digester for a quantity of water and cow dung

[jonule]

well it depends on the number of cows!

otherwise I made 1 page here:

including a link on eden which will give you everything!

[Christophe]

Precisely for what quantities?

You should find indications on these links:

2 concrete examples of biogas on the farm
Methanogenic powers
Example: large biogas plant in jundhe

And for your project, I recommend the purchase of this book:

I am not competent in this area, but as I see that you live in Dakar, I would like to ask you your opinion on the cancellation of the Lisbon-Dakar (subject mentioned in another post on this forum).

How does it feel about you? Does this ordeal bring anything positive in humanitarian terms for the African countries crossed?

For this we can continue the exchange on:

Are you in Africa? I hadn't seen that! Thank you Jean.

In this case the problem is not at all the same and these pages, should greatly help you! I thought you were in France ...

Biogas Biomethanization Project in Africa

Basically according to my estimates it takes 10 kg of "shit" to make the equivalent of a liter of fuel oil, that is to say 1,5 m3 of biogas (ladle). The volumes are therefore very quickly important if one does not compress the gas or that one does not use it directly.

this is how éric florantine does:
he uses 200 L metal drums that he welds!

there are flexible feeders of different capacity 5,10 30m3, I saw that at the fair, to store various waste (liquid manure .....)
