Abstract

Swim-bed (BioFringe (BF) carriers used) together with Stick-bed (BioFix (BX) carriers used) will generate new applications of biological wastewater treatment. A pilot study includes anoxic, aerobic, and sedimentation tanks. The unit of analysis is raw domestic wastewater with COD loading rates of 0.75 – 1 – 1.5 - 2 kg COD/m3/day. The treatment in this study is best obtained when the organic loading rate is 0.75kg COD/m3/day and 1kgCOD/m3/day; specifically: all demands decrease Biological oxygen 86.9%; Chemical oxygen 89.8%; Total suspended solid 91%; N – Ammonia 70.7%; Total phosphorus 50%. The study results bring about great potentials to treat nitrogen in wastewater.
