The performance of membrane bioreactor treating high temperature wastewater

Abstract

Membrane bioreactor technology represents the most rapidly growing membrane technology in the water sector. In recent years, MBR technologies have been playing a very important role in water and wastewater treatment. MBRs are used to treat a wide range of municipal and industrial wastewaters. MBR integrates membrane filtration with biological degradation system of waste products. It is defined as a modification of the conventional activated sludge system (AS), where the separation of the treated water from the mixed liquor is accomplished by a membrane system instead of a clarifier. The two basic MBR process configurations are external and submerged. The high cost of pumping makes external MBR system impractical for full-scale municipal wastewater treatment plants. In this study, submerged MBR (SMBR) process was developed.
