Ultra-filtration (UF) is a membrane separation technology that purifies and separates solutions. The ultrafiltration membrane system is a solution separation device in which an ultrafiltration membrane is as a filter medium and a pressure difference on both sides of the membrane is a driving force. The ultrafiltration membrane only allows the solvent (such as water molecules), inorganic salts and small molecular organic substances in the solution to pass through, and the macromolecular substances such as suspended matter, colloid, protein and microorganisms in the solution are intercepted, thereby purifying or separating.

Ultrafiltration (UF) Systems Advantages

Ultrafiltration (UF) membranes systems are more reliable than a conventional multi-media filter, which removed approximately 10 micron or larger of matter, where an ultrafiltration membrane pore size ranges from 0.01 to 0.10 micron. In addition to superior turbidity removal, UF membranes efficiently remove bacteria and most viruses.

- Superior filtration performance with high flux

- Very small nominal pore diameter (0.03 µm)

- Efficiently removes bacteria and viruses

- Occasionally back washed and air scoured to boost performance and removing the fouling layer to extend operating life

- Low fouling membrane modules

- UF Outside-In or Inside-Out Configuration permits reduced plugging and higher solids loading

- Basic, vertical, modular design permits low cost, compact systems

- Effective membrane cleaning has a high chemical resistance and temperature tolerance
