This ultrafilter adopts dissymmetriacal semipermeable film which is made from macromolecule material with special process. The raw liquid flows under pressure, inside or lut side the film. The macromolecule substance and colloid particles in the raw liquid are clogged at the film suface and are brought away by circulating raw liquid. Then the raw liquid becomes inspissated, furthermore, the subtance in liquid is seperated, concentrates.

Hollow filber filter
Ultra-filtration (Ultra-filtration, UF) is a membrane separation technology that can purify and separate solutions. The ultrafiltration membrane system is a solution separation device with ultrafiltration membrane filaments as the filter medium and the pressure difference on both sides of the membrane as the driving force. Ultrafiltration membranes only allow solvents (such as water molecules), inorganic salts, and small-molecule organics in the solution to pass through, while retaining macromolecular substances such as suspended solids, colloids, proteins and microorganisms in the solution to achieve the purpose of purification or separation.
