| Abstract |
Experiments were conducted to investigate the effect of MLSS concentration on the performance of a sequencing batch reactor (SBR) treating industrial wastewater containing high concentration of organics and nitrogen. Three laboratory-scale reactors were designed and operated at different MLSS concentration. Total organic carbon and nitrogen concentration in the reactors were monitored over reaction time. The higher MLSS concentration in the reactor resulted in the greater COD removal rate with up to 1.24㎏ COD/㎥.day. The higher MLSS concentration resulted in the lower TOC concentration in the effluent. It was observed from monitoring ammonia in the reactor that the higher MLSS concentration in the reactor resulted in the higher rate of ammonia oxidation and the earlier production of NO₃-N. MLSS concentration was observed to be an important factor determining removal rate of organic and ammonia |
