Outside-in UF Membrane
A central tube is placed In the middle of the UF membrane. When the raw water inlet is in the open state and the outlet is in the closed state, it contributes to the raw water flowing into the central tube only and entering into hollow fiber membrane filaments for filtration under the action of pressure. When the hollow fiber membrane inlet is in the closed state and the outlet is in the open state, it contributes the concentrate discharge.
- Mostly made of PVDF, and can withstand higher concentration of oxidant for a long time;
- Composite membrane, it has two layers of membrane walls with independent inner wall support layer, which makes it not be damaged by external pressure;
- It has higher dirt holding capacity and larger filtration area, making the cleaning easier and more complete;
- It has excellent fouling resistance and can remove almost all fine particles, bacteria, most bacteria, colloids and other impurities.
- Its outside-in flow ensures the permeate stability and good water quality;
- It is widely used in the fields of RO system pretreatment, industrial wastewater deep processing and reuse, reclaimed water reuse.
