Damai’s 10 inch ultrafiltration (UF) membrane cartridges are high-precision filtration elements designed for the removal of bacteria, viruses, colloids, and suspended solids from water and process fluids. Utilizing hollow fiber or flat sheet membranes with pore sizes ranging from 0.01µm to 0.1µm, these cartridges ensure high flux, excellent filtration efficiency, and low operating pressure.
UF membranes are ideal for applications requiring high-quality water without compromising on flow rate. Damai supports fully customizable UF cartridge solutions, including membrane material, pore size, housing format, and end caps, tailored for OEMs, water treatment integrators, and industrial users.
