Optimization of Ultrafiltration Membranes in MBR Modules for Enhanced Water Purification
Membrane bioreactors (MBRs) are effective wastewater treatment systems that utilize ultrafiltration membranes to remove suspended solids and microorganisms. However, the efficiency of MBRs can be limited by membrane fouling, which leads to decreased water quality and increased operational costs. Therefore, optimizing ultrafiltration membranes for enhanced water purification is crucial for the success of MBR technology. Several strategies have been investigated to improve membrane performance, including modifying membrane materials, altering operating conditions, and implementing pre-treatment methods.
