    Abstract

    This study investigated the elimination of pharmaceuticals in pre-denitrifying moving bed biofilm reactors (MBBRs) in single- and three-stage configurations. Under batch conditions, biotransformation and retransformation of two pharmaceuticals (trimethoprim, sulfamethoxazole) occurred at comparable or higher rates than in denitrifying activated sludge. Based on estimated rate coefficients, concentrations in continuously operated MBBRs were predicted.
