Attached a review article on how to enhance biogas plants using various means. It has a long list of references thus it might be a good starting point for further research.

Thanks Christoph,
I will try to get this very specific and expensive book trough Universities.

Dear Detlef,

as you are German as well, I recommend you "Anaerobtechnik" from Springer Verlag (you might know but just in case).
It gives a very wide range about everything, but I remember a chapter which is exactly dedicated to the aspects you mentioned.

2 two stage anaerobic process (mesophilic) is more common in waste treatment so in this direction you might find something, in domestic wastewater it is hardly used.

Yours Christoph

Dear Colleagues with biogas know-how,

I have a very specific know-how "request": Could some body recommend to me a good source of online literature about practical and theoretical information on multi-stage biogas-digesters for continuous mode only, at least for a two-stage systems like hydrolysis & acidogenesis and acetogenesis & methanogenesis for mesophilic temperature range? Of course this is all-ways very much depending on substrate and co-substrate used, so "only" domestic sewage and algae as co-subtrate are interesting for the time being.

Information I found in many text-books and Internet have often contradictions to each other, so I do not know which information I could trust... Often only very theoretical laboratory batch tests been used as a base of know-how.

Important for me is for now "only":
- needed different temperatures ranges by stage,
- pH range,
- HRT range,
- SRT range and
- time range needed for granulation's

for the two stages.

Any suggestions or advices on the subject are highly welcome.
Thanks in advance.


Best Regards,
Detlef
