Membrane Aging and Replacement

In a well-maintained system, the modules used in a membrane bioreactor (MBR) are predicted to have a usable life of between 8-10 years. Given that MBRs are used to produce water for recycling schemes, requiring continuous compliance with design log removal values (LRVs) of pathogens. The aim of this study was to assess temporal changes in LRV for a suite of microorganisms, for time scales relevant to the expected life of modern MBR modules.
