Products Description
General Information
VNT-MBR-500D membrane is manufactured as analogue of Suez Zeeweed 500D MBR modules.VNT-MBR-500D hollow fiber MBR membrane modules are designed and manufactured mainly for wastewater and sewage treatment plants. Consisting of a 0.04 micron PVDF ultrafiltration hollow fiber membrane, VNT-MBR-500D MBR modules provide excellent physical barrier to suspended solids, bacteria and other pathogens. The uniform pore size distribution ensures high permeability and sustainable high-quality filtrate.The new generation of large VNT-MBR-500D modules for MBR applications are upgrade-designed and improved, while continuing to leverage the aeration and header design.Advanced manufacturing process of arraying fibers avoids twined fibers and less sludge accumulation, leading to sufficient filtration area, high flux and better backwash performance. The highest fiber tensile strength assures no fiber breakage in whole service-life operation.VNT-MBR-500D submerged hollow fiber membrane modules are providing professional, comprehensive wastewater and sewage solutions to industrial and municipal applications around the globe.
