General Information

TaFlux HFU series ultrafiltration (UF) membrane module is a pressurized module, which is designed and manufactured for the filtration of surface water, potable water, seawater, industrial wastewater and municipal sewage. These UF modules are made of new generation PVDF hollow fiber membrane with high fouling resistance and hydrophilicity.
TaFlux HFU series UF module is applied in new systems, as well as directly connected to existing UF systems as replacements, providing high-quality filtrate by removing suspended solids, colloids, pyrogens, bacteria, viruses and other impurities to protect downstream processes.
