As essential pretreatment equipment before deep purification, water filter element UF membrane series, also called Ultrafiltration membrane module, effectively filter out colloidal impurities, algae, microorganisms and tiny suspended particles in raw water. Installed in front of the RO membrane system, the UF membrane module greatly reduces fouling speed of Reverse Osmosis membrane and lowers the cleaning frequency of the whole water treatment system. Combined with front-end high flow filter, the Ultrafiltration membrane forms two-stage pre-filtration to guarantee stable inflow water quality for RO membrane element.
Working Principle of UF Membrane Module
Raw water flows into the housing and passes through hollow fiber tubes of the UF membrane. Water molecules and small soluble ions penetrate the hollow fiber wall to form ultrafiltration clear water. Colloids, bacteria, macromolecular organic matter are intercepted on the outer surface of the Ultrafiltration membrane. Timely cross-flow backwashing cleans dirt on the membrane surface, keeping stable flux of the UF membrane module for long-term continuous operation.

Four Major Product Advantages
1 Super High Interception Precision
0.01μm hollow fiber UF membrane completely traps colloids and microorganisms harmful to RO membrane.
2 Excellent Hydrophilic Property
PVDF hydrophilic Ultrafiltration membrane is not easy to be blocked by organic dirt, easy backwashing regeneration.
3 Simple System Matching
Standard module size of the UF membrane module is easy to assemble before any RO membrane element.
4 Low Operation Cost
Long service cycle of the Ultrafiltration membrane reduces replacement and maintenance expenses.
Main Application Fields
This industrial UF membrane module is widely used as pretreatment for pure water equipment, sewage recycling, food beverage water and chemical process water. As necessary pre-filter of the RO membrane, the Ultrafiltration membrane effectively extends the service life of Reverse Osmosis membrane element and stabilizes the water production efficiency of the whole desalination system.
