Adjustment of Operating Factors in Ultrafiltration Membranes for MBR Uses

Membrane bioreactors (MBRs) are increasingly employed in wastewater treatment due to their ability to produce high-quality effluent. Ultrafiltration (UF) membranes play a crucial role in MBR systems by separating biomass from the treated water. Optimizing UF membrane operating parameters, such as transmembrane pressure, crossflow velocity, and feed concentration, is essential for maximizing efficiency and extending membrane lifespan. High transmembrane pressure can lead to increased fouling and reduced flux, while low crossflow velocity may result in inadequate removal of suspended solids. Fine-tuning these parameters through empirical methods allows for the achievement of desired effluent quality and operational stability within MBR systems.
