Production of extracellular polymeric substances in anoxic/oxic process with zeolite carriers for nitrogen removal.
During the hydraulic retention time (HRT) from 12 to 6 h, the production of extracellular polymeric substance (EPS) decreased from 82 to 70 EPS mg volatile suspended solids (VSS) g(-1) in an anoxic/oxic (A/O) reactor with zeolite carriers. Added zeolite could successfully control the EPS production by the formation of stable biofilm and the maintenance the lower chemical oxygen demand/ammonium (C/N) ratio on its surface.
