HYDRAMEM · PVDF ultrafiltration membranes
HM PureULTRA PHF-80-V
Pressure-driven PVDF ultrafiltration module.
HYDRAMEM PureULTRA modules feature a polyvinylidene fluoride (PVDF) hollow fibre UF membrane that offers high chemical tolerance along with physical robustness. The tight pore size helps in the removal of solids, pathogens and other suspended foulants, and the unique PVDF polymer allows the modules to be cleaned aggressively without decline in operating flux. PureULTRA modules treat the entire spectrum of feed waters from sea, surface and well sources to secondary and tertiary wastewaters, both industrial and municipal.
