We used PAC-MBR to remove iron, manganese and ammonia from groundwater. The PAC-MBR system could produce a good effluent when purifying a broader range of influent. Cake layer containing PAC and oxides was the main reason for membrane fouling. Leptothrix, Pseudomonas, Hyphomicrobium, Planctomyces, Nitrosipiras and Nitrosomonas played major roles in PAC-MBR systems.
