| Abstract: | Summary Immobilized activated sludge system with porous polyurethane foam pads was operated in time-sequenced anoxic/oxic batch mode for the enhanced nutrient removal. Biomass hold-up in polyurethane foam pads in immobilized sytem increased with incoming organic substrate concentration. This new trouble-free system showed improved capability in nitrogen and phosphorus removal than conventional activated sludge system. |
