Treatment of synthetic wastewater by combining submerged MBR technology and aerobic granular technology
In order to enhance performances of organics and nitrogen removal for the treatment of synthetic wastewater containing higher concentration of organic solids, nitrogen and phosphorus than conventional biological phosphorus removal process, a submerged membrane bioreactor was combined with an aerobic granules technology (aerobic granular sludge membrane bioreactor, AGSBR) in this research. The results presented a remarkable enhancement of the effluent quality in terms of COD removal and nitrification. Total Nitrogen and TOC removal in a typical cycle revealed good and stable performance during the experimental period. Scanning electron microscopy (SEM) analyses were performed to compare the morphological changes between new and after cleaning membrane surface. The findings indicated that the AGSBR system was in possession of huge potential for controlling membrane fouling.
