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 performance of MBRs can be constrained 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 sustainability of MBR technology. Several strategies have been studied to enhance membrane performance, including modifying membrane materials, altering operating conditions, and implementing pre-treatment methods.
