Biomass observed yield values were calculated for a full-scale biological aerated filter (BAF). Three individual mass balances were conducted to quantify the consumption of soluble COD in the filter and the mass of influent particulate matter filtered from the waste stream. Retained particulate matter is a substrate source for the biomass; however, the particles must be hydrolyzed into metabolizable forms before being consumed by the biomass. A bench-scale BAF was designed and constructed to investigate the degree to which particle hydrolysis occurred in the full-scale system. Using two independent bench-scale BAF experiments, it was determined that 40.0 and 46.3% of influent particle mass as COD underwent hydrolysis. Calculated biomass observed yields for the full-scale BAF ranged from 0.43 to 0.48 mg of biomass as COD generated per mg of substrate consumed as COD.
