From the literature review it is apparent that BF-MBR systemshave not been tested for marine aquaculture application, thoughsome work has previously been conducted to test the potential ofintegrating AS-MBR systems in marine RAS. However, this is not afully established and commercialized practice to date. An AS-MBRin freshwater RAS was investigated in 2002 by Viadero and Nobletfor removal of fine solids. They suggest membrane filtration forniche applications such as larval fish culture. A study by Pulefouet al. (2008) showed that using an AS-MBR treatment system inRAS created an effluent with turbidity of less than 0.5 NTU. A studyby Sharrer and Summerfelt (2007) showed that the AS-MBR per-formed exceptionally well during operation, with nearly completeremoval of cBOD5, TSS and bacteria, and a biological treatment ofnitrogen through nitrification/denitrification indicated consistentremoval of total nitrogen. In a subsequent study permeate flowwas found suited to be reclaimed in fish cultures to recycle alkalin-ity, salts, heat and water under biosecure conditions (Sharrer et al.,2010)
