PureUltra ii PHF 80

Summary

The PureULTRA PHF-80-V UF module is a pressure-driven ultrafiltration module featuring a Polyvinylidene Fluoride (PVDF) hollow fiber membrane. This membrane offers high chemical tolerance and physical robustness with a tight pore size of 0.025 µm, which helps in the removal of solids, pathogens, and other suspended foulants. The unique PVDF polymer allows for aggressive cleaning without loss of operating flux or membrane hydrophilicity. PureULTRA UF modules are designed for consistent filtration efficiency and durability, suitable for treating a wide range of feed waters including sea, surface, well, and secondary & tertiary wastewaters (both industrial and municipal).
