Influence of PVDF Membranes in Enhanced Nutrient Removal by MBRs
PVDF films play a crucial function in enhancing nutrient removal within membrane bioreactors (MBRs). Their specific chemical and physical properties contribute to efficient purification of organic matter, nitrogen, and phosphorus. PVDF membranes exhibit excellent permeability, allowing for a steady flow of treated water while effectively retaining nutrients within the bioreactor. The tight pore structure of PVDF membranes prevents the flow of suspended solids and microorganisms, promoting purity in the effluent. Moreover, PVDF's resistance to accumulation ensures prolonged membrane effectiveness, minimizing operational issues.
