Characteristics of the Bio-enhanced powder activated carbon dynamic membrane reactor for municipal wastewater treatment

A Bio-enhanced powder activated carbon dynamic membrane reactor (BPDMR) was designed, which combined the advantages of both microbial reactor and dynamic membrane, and is a new municipal wastewater treatment technology. Based on a laboratory-scale anoxic-oxic (A/O) process, the dynamic membrane is used as the key factor of intercepting suspended solids (SS) and colloidal particles. Simultaneously, experimental results indicated that the system had the advantages of high filtration flux, low filtration resistance, easy back washing, and higher removal efficiency of the pollutants.
