Working Principle

Ultra-filtration is a pressure-driven purification process in which water and low molecular weight substances permeate a membrane while particles, colloids, and macromolecules are filtered. The primary removal mechanism is size exclusion. A properly designed UF cartridge allows efficient rising of ionic residue from the cleaning and rapidly returns to optimal resistivity and organic purity.
