Enhanced Removal of Organic Pollutants by a Hybrid Membrane Bioreactor using PVDF Membranes
A novel hybrid membrane bioreactor (MBR) employing PVDF membranes has been developed to achieve enhanced removal of organic pollutants from wastewater. The MBR combines a biofilm reactor with a pressure-driven membrane filtration system, effectively treating the wastewater in a sustainable manner. PVDF membranes are chosen for their superior chemical resistance, mechanical strength, and compatibility with diverse wastewater streams. The hybrid design allows for both biological degradation of organic matter by the biofilm and physical removal of remaining pollutants through membrane filtration, resulting in a considerable reduction in contaminant concentrations.
This innovative approach offers advantages over conventional treatment methods, including increased removal efficiency, reduced sludge production, and improved water quality. Furthermore, the modularity and scalability of the hybrid MBR make it suitable for a spectrum of applications, from small-scale domestic wastewater treatment to large-scale industrial effluent management.
