Pleated Membrane Cartridges


Treliving Engineering Supplies offer a wide range of membrane cartridge filters for fine filtration for purification of water, acids, bases, inks and other solutions. All membrane cartridges are pleated to increase the face area and dirt holding capacity. Cartridges are rated to a known and tested change-out pressure difference (dP) to help determine planned change-outs and number of cartridges required. We offer a range of filter media to suit varying applications.
