PES Hollow Fiber UF Membrane
Hollow Fiber UF Membrane Introduction
Ultrafiltration membrane belongs to capillary hollow fiber membrane,It is a polymer material membrane,It is a separation product without phase change.With the material of modified PVDF and PES, It has good water permeability, mechanical properties, chemical resistance and pollution resistance. The Module type is Outside-in(PVDF) and Inside-out(PES). It can filter various harmful substances such as bacteria, colloids, suspended solids and microorganisms which are in the feed water.
Hollow Fiber UF Membrane Application
Water Treatment:
sterilization, turbidity removal and purification of tap water, groundwater and surface water; pretreatment of reverse osmosis.
Wastewater Treatment and Reuse:
urban reclaimed water reuse, industrial wastewater treatment and reuse, hospital wastewater, and treatment of oilfield reinjection water.
Seawater Desalination:
seawater purification and seawater desalination pretreatment.
Medicine and Biotechnology:
separation and refinement of traditional Chinese medicine extracts, depyrogenation of medical sterile water and water for injection, separation and purification of biological products, and blood purification.
Food and Cooking Materials:
clarification of fruit and vegetable juices and wine, filtration and sterilization of milk, concentration and purification of whey.
Hollow Fiber Membrane Material
The hollow fiber materials are polyvinylidene (PVDF) and polyvinyl alcohol (PES), these materials have the following characteristics:
The microstructure of the hollow fiber membrane is a sponge structure and the pores change in gradient, which is stronger than the traditional finger-shaped pore structure and has stronger anti-pollution ability.
Good hydrophilicity, uniform membrane pore size, and large water permeability per unit area.
Good heat resistance, strong chemical stability, good resistance to chemical cleaning.
It operates under ultra-low pressure and has low energy consumption.
