The anaerobic fluidized bed biofilm reactor (AFBBR) was evaluated as a means for corn starch wastewater pretreatment. Laboratory results indicate that good chemical oxygen demand (COD) reduction and methane production are achievable in AFBBRs operated at proper food:microorganism (F:M) ratios. Over 70% of feed COD can be removed and 15 L/d of methane can be produced at F:M ratios as high as 3.45 g COD/g TVS-d. Reactor biomass holdups greater than 15 000 mg/L are achievable in AFBBRs. The combined effects of biofilm detachment, biofilm growth, and intentional bioparticle wastage and biofilm separation cause finite AFBBR mean cell residence time (MCRT). A desirable MCRT is achievable in AFBBRs that will ensure good COD reduction and methane production. J. Water Pollut. Control Fed., 60, 1826 (1988).
