A Pilot-scale Study of Membrane Fouling Control for Membrane Bioreactor(MBR) |
| |
| Abstract: | A pilot-scale hollow-fiber micro- filtration membrane bioreactor with a treatment capacity of 30 m3/d was built for studying the deep treatment of municipal wastewater. The effect of membrane unit construction, membrane aeration, back washing, and chemical cleaning on membrane fouling was investigated. The optimal design and operation parameters were summarized. The operation and maintenance of membrane unit was optimized to achieve membrane fouling alleviation, membrane cleaning frequency reduction, membrane service life extension, and operation cost reduction. |
