i rescue a mail i sent weeks ago about this subjet:
 
Hi everybody.In the last moths im meeting people who is installing tubular biodigesters and they are using 1:2 manure:water rate to feed the biodigesters. From five years ago i started using 1:4 rate (recomended by Lylian Rodriguez and Preston), but from two years ago im using 1:3 because the in some places the are not that much water for 1:4.the reason tu use 1:3 or 1:4 is to avoid the formation of the foam that stop the production of biogas. But if really you can work wiyh a lower rate (1:2) without problems with the foam, this will be a great issue, because the volume required wil be lower and the cost os materials and biodigester as well.So please, have you got good expiriences with low rate manuere:water for long time with out foam?thanks everybodywe keep in contactjaime> Date: Wed, 12 Sep 2007 19:52:41 -0700> From: weiswar at yahoo.com> To: Digestion at listserv.repp.org> Subject: [Digestion] Floating manure> > > > > Do large digesters just add more water? > > My thinking was to weight it down with a steel screen.> Thoughts? > > > > ____________________________________________________________________________________> Be a better Heartthrob.
