Effect of recycle on treatment of aircraft de-icing fluid in an anaerobic baffled reactor

Abstract

3 July 2005 Boopathy and Tilche (1991) treated molasses wastewater in an ABR with granular biomass and reported that the improved settling characteristics of granular sludge (compared to bioflocs) increased the SRT and produced an effluent that was lower in suspended solids. Hutňan et al. (1999) reported on the methanogenic and non-methanogenic activity of granulated biomass in a four compartment ABR as compared to a UASB reactor. The authors found that the ABR had maximum specific hydrolytic and acidogenic activities that were 10 to 25 times and specific methanogenic activity 2 times higher than the UASB reactor.
