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

A key factor in achieving superior removal efficiency within a hollow fiber membrane bioreactor (MBR) system lies in the careful optimization of its operating parameters. These parameters, which include variables such as transmembrane pressure (TMP), feed flow rate, and aeration level, exert a profound influence on the performance of the MBR system. By meticulously adjusting these parameters, it is possible to maximize the removal of contaminants such as organic matter, nutrients, and suspended solids from wastewater.

For instance, elevating the TMP can promote membrane permeation, leading to a improved flux rate and consequently, a faster removal of pollutants. Conversely, modifying the feed flow rate directly impacts the hydraulic retention time (HRT), which in turn affects the efficiency of the biological treatment process within the MBR system.

Furthermore, the aeration rate plays a vital role in maintaining the health of the microbial community responsible for treatment of organic matter. An optimal aeration rate ensures adequate dissolved oxygen levels, which are indispensable for efficient microbial activity.
