1, permanent hydrophilic, large amount of water, no smell.
2, dry film, no smell, no need of glycerin moisturizing, rinse without foam, COD not exceeding standard.
3, high oxygen resistance, resistance to chloride (200ppm sodium hypochlorite for 72 hours, the performance of no change)
4, flexibility is good, stretching length is greater than 100% is not easy broken wire, can be repeated washing, the service life of up to 3-5 years.
5, unique permanent hydrophilic modification, so that the hydrophilic contact angle of the membrane material is less than 45 degrees, the formation of the excellent anti fouling performance of PVDF membrane, not easy to plug, over water, long use time.
6, film, not afraid of broken wires, with self-healing function.

Ultrafiltration (UF) is an important water purification technology used for production
of high-purity water. Ultrafiltration is effective in the removal of colloids, proteins,
bacteria, pyrogens (e.g. gram-negative bacterial endotoxins), and other organic molecules
larger than 0.1 Micron size.
Ultrafiltration 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 redidue from the cleaning and rapidly returns to optimal resistivity and
organic purity.
