[Digestion] Slurry drier

Frans, Hello,
Strictly speaking, you do not need cattle dung to start the plant, but it 
does speed things up. Suitable microbes will find their way into a biogas 
plant, but this can take a long time. Cattle dung introduces the right 
microbes at the right time. Once a population of the right microbes has 
been built up, they should continue. You should only need more cattle dung 
if there is a problem. 

Best Wishes,  


David

Thanks Paul for your points. Yes I had been told to start with cow dung 
first, which is where I was at when it exploaded!. What I have not been 
able to find is anyone who has then continued with chicken droppings for 
any length of time. Will I have to continually re-inocculate with cow 
dung?


Your comment on the sand filter is of interest, I will have to run some 
tests, tho I do see a problem in summer with the heavy rains.

Thank you.

    G'day Frans,


      I hope by now that someone has pointed out that chicken manure
      does NOT contain methanogens, so you will get CO2 but not biogas.
      You need to innoculate the digester with cow or pig manure then
      change to chicken manure in a couple of steps.


      Good luck,

      HOOROO

Hi all.  For the record, failed in my first attempt! Had a bag
        made of heavy 'sail' in South Africa, cost a lot! About 10m long
        X 1m high with heat welded seams. It lasted less tha 24 hours
        and 1 of the seams burst. What a mess!

        Will now have to sandwhich all seams between 2 pieces of flat
        bar & try again.

        We live, & hopefully learn from our mistakes.

        Assuming I can get beyond the the next 24 hours! Can anyone out
        there shed any light on, a) biogas from pure chicken droppings,
        ie from layers in cages.

        b) I desparately need a way to remove the excess water from the
        slurry. (For the moment lets assume that cost is not a problem).
        

        Any & all ideas would be most appreciated.

        I do not have access to spare land, so lagoons or sun drying is
        out, nor can I get sufficient vegitative, grass, etc

        Please help
