Optimization of Operating Parameters in a Hollow Fiber MBR System for Enhanced Removal Efficiency

A key factor in achieving optimal removal efficiency within a hollow fiber membrane bioreactor (MBR) system lies in the careful optimization of its operating parameters. These parameters, which include factors such as transmembrane pressure (TMP), feed flow rate, and aeration level, exert a profound influence on the performance of the MBR system.
