Title

EFFECT OF SLUDGE PRETREATMENT ON THE PERFORMANCE OF ANAEROBIC/ ANOXIC/ OXIC MEMBRANE BIOREACTOR TREATING DOMESTIC WASTEWATER

Pages

  281-290

Abstract

 In the present study, two bench-scale anaerobic/ anoxic/ oxic submerged MEMBRANE BIOREACTORs were used to study the effect of thermochemical sludge disintegration system on the excess sludge production. Among the two MEMBRANE BIOREACTORs, one was named experimental MEMBRANE BIOREACTOR and another one was named as control MEMBRANE BIOREACTOR, where a part of the mixed liquor was treated with thermo chemical and was returned back to MEMBRANE BIOREACTOR. Thermo chemical digestion of sludge was carried out at fixed pH (11) and temperature (75oC) for 24% chemical oxygen demand solution. The other one was named control MEMBRANE BIOREACTOR and was used as control. The reactors were operated at three different mixed liquor suspended solids range starting from 7500 mg/L to 15000 mg/L. Both of MEMBRANE BIOREACTORs were operated at a flux of 17 LMH over a period of 240 days. The designed flux was increased stepwise over a period of one week. During the 240 days of reactor operation, both of MEMBRANE BIOREACTORs maintained relatively constant TRANSMEMBRANE PRESSURE. The sludge digestion had no impact on chemical oxygen demand removal efficiency of the reactor. The results based on the study indicated that the proposed process configuration has potential to reduce the excess sludge production as well as it didn’t deteriorate the treated water quality.
