Optimization of Operating Parameters in a Hollow Fiber MBR System
Optimizing process parameters in a hollow fiber membrane bioreactor (MBR) system is crucial for achieving high removal efficiencies and sustainable performance. Key parameters that require fine-tuning include transmembrane pressure, feed flow rate, aeration rate, and backwash frequency. Modifying these parameters based on the specific properties of the wastewater and the operational targets can significantly impact membrane fouling, biomass growth, and overall system efficiency.
