Hollow Fiber Membrane elements

Short Description:

Hollow fiber membrane is a kind of asymmetric membrane shaped like a fiber with self-supporting function. The membrane tube wall is covered with micropores, which can intercept substances with different molecular weights, and the MWCO can reach thousands to hundreds of thousands. The raw water flows under pressure outside or inside the hollow fiber membrane, forming external pressure type and internal pressure type respectively.

The industrial application of hollow fiber ultrafiltration membrane modules and devices can be used in three aspects: concentration, separation of small molecular solutes and classification of macromolecular solvents. It is widely used in water purification treatment to remove bacteria, viruses, suspended solids, microorganisms, macromolecular organics, colloids, heat sources, etc. It is also widely used in chemical separation, medicine and health care, food processing, filtration and purification of tea drinks, vinegar and wine, etc.
