Abstract

The invention presented is a method for improving biogas generation by segregation of the two stages i.e. acidogenesis and methanogenesis by means of two separate reactors and semi- permeable membrane unit. The semi- permeable membrane unit permits the migration and concentration equilibration of low molecular size fatty acids but does not permit the migration of high molecular weight undigested, semi-digested feed as also of microbial cells. The transportation of volatile fatty acids is brought about by circulating the acid filtrate and the slurry containing the methanogenic microorganisms on two sides of a semi permeable membrane thus permitting concentration equilibrium of volatile fatty acids with the contents of the methanogenic reactor without exchanging the two microbial populations. The overall effect is faster conversion of feed into biogas without undue loss of the methanogens.
