From responses observed in this study the potential benefits of a RAS system that integrates membrane filtration for advanced treatment of the recycle stream are apparent. However, a key aspect of any membrane filtration system is membrane fouling behaviour and control. In this study the membrane unit was monitored toassess the performance and behaviour of this separation process.Membrane performance is typically assessed by monitoring thechange in transmembrane pressure (TMP), which is an indirectmeasurement of membrane permeability decline due to foulingphenomenon. The TMP measured over the duration of this studyis shown in Fig. 6. During the experiment the membranes had tobe chemically cleaned two times, seen as two peaks on the graph(Fig. 6). Operating conditions for the membrane filtration unit was based on conservative set points which are commonly used for MBR systems when applied in waste water treatment. The fouling rates observed in this study are comparable with reported values from various studies on advanced waste water treatment. It should be noted that a detailed investigation of the membrane performance was not the aim of this study, however, results from this study demonstrate that integration of a BF-MBR process in RAS is both feasible and practical. More detailed studies of membrane systemsapplied and optimal operating conditions are required for full-scaleimplementation and commercialization of mRAS solutions
