Abstract

Sprouse and Rittmann showed that biofilm colonization increased the colloid cohesion efficiency, alpha, when the collector was granular activated carbon (GAC) in a methanogenic fluidized bed and the colloids were milk solids of a particular diameter. Virgin GAC gave an alpha so low that it was indistinguishable from zero, but biofilm colonization at 0.134 mg cellular carbohydrate per gram dry carbon gave an alpha value of 0.21. This note reports further studies showing that increased biofilm colonization dramatically increased alpha and improved colloid removal in an anaerobic, fluidized bed biofilm reactor.
