~Function and Application:

UF water treatment system can get rid of particles,colloid substances,bacteria and heat producers in water.It's applied to purification,separation and concentration in chemical industry,food industry,environmental protection,electronic industry,textile industry etc.

By using hollow fibers UF membrane as filtration media, raw water particles which are smaller than pore of UF membrane will permeate through and collected as permeate; whilst, particles which are larger than UF membrane pore size will be separated as concentrate under certain pressure applied.

UF membrane is an asymmetric semipermeable membrane made of high molecular material by special technology. Its' hollow fiber tube cover densely by micropores which allow solution flowing in or out the membrane under the influence of pressure. UF membrane pore size range from 0.1 to 0.005 μm or molecular weight (200,000 to 10,000 Daltons) for different applications.

Generally, it is used to remove high molecular- weight substances, colloidal materials, bacteria, organic and inorganic polymeric molecules.

UF system requires ONLY 20% energy consumption of reverse osmosis system. Low operating pressures are sufficient to achieve high flux rates from UF membrane
