SWT PES Membrane Cartridges
SWT’s Polyethersulfone (PES) Membrane Cartridges have been developed for the filtration of high purity liquids.
SWT’s Polyethersulfone (PES) Membrane Cartridges are inherently hydrophillic and contain no added surfactants or wetting agents. Each cartridge is fabricated in a cleanroom environment. This cartridge’s greatest strength derives from the use of its unique mirrored anisotropic polyethersulfone membrane with a narrow pore size distribution. This membrane produces a cartridge with exceptionally high flow rates and long on-stream life.

Safe Water Technologies PES membrane and all-polypropylene supportive structures result in a cartridge with low ionic and organic extractables, broad chemical compatibility, and a high resistance to hydrolysis, thus minimizing particle shedding.
