WPS Cartridge Filters Polyethersulfone (PES) Membrane Applications Process Water Ultrapure Water Pharmaceutical Waters Dimensions Length Outside Diameter Filtration Area Maximum Operating Parameters Differential Pressure • Forward • Reverse WPS Filter Cartridges with symmetric polyethersulfone (PES) membrane are ideal for purified water filtration. The symmetric membrane used in WPS cartridges guards against bacterial growthrough during the long life of the filter, reducing the potential for biofilm accumulation in system piping. WPS cartridges are flushed with high purity water to remove manufacturing debris.
