Data presented covered plant operation, operational costs and a comparison of the pathogen and virus removal of the RWP from two separate studies. DATA-DRIVEN The existing membrane modules were installed for nine years and were the subject of: • a study conducted about operation of the existing system and the impacts on performance; and • a review conducted on filtrate quality. An upgrade with Memcor B40N membrane modules and a MemPulse aeration system followed, and found: • the upgrade was within the existing tankage with the RWP online; • the upgrade allowed the plant capacity to be increased up to 3ML/d average flow from the current rated average flow of 2ML/d; and • the use of large bubble slug flow of the MemPulse system meant that the scour air blowers did not have to be increased in capacity.
