Abstract

Employing high rejection forward osmosis (FO) membranes, FOMBR showed distinctive new features. Our research in the past few years was carried out on the development of this new process. The high rejection property of the FO membrane was explored for direct phosphorus recovery from municipal wastewater. A hybrid MF-FOMBR configuration was further developed to control the salinity build-up and to facilitate the recovery of nutrients. We also uncovered new features of the FOMBR in terms of the decoupling of contaminants retention from HRT, which resulted in high throughput wastewater treatment with enhanced phosphorus recovery. In a nutshell, the use of high rejection FO membranes in the FOMBR raised challenges, but also conferred this process unparalleled advantages beyond that of a novel MBR. Research in these aspects is likely to present new ideas for the development of “next generation” membrane bioreactors for wastewater treatment.
