Are MEMBRANE BIOREACTORS Ready for Widespread Application?

摘要

There's a lot to admire about membrane bioreactors(MBRs).This emerging waste-water-treatment technology combines a suspended growth biomass,similar to those used in the traditional activated sludge process,with a membrane system that replaces gravity sedimentation and that retains biomass and clarifies effluent(1-4).MBRs offer a host of technical advantages over activated sludge systems,such as small size,and seem to be well suited for applications such as water reuse.
