Ultrafiltration (UF) is a membrane filtration to remove suspended solids, solutes with high molecular weight, bacteria, viruses, endotoxins and other pathogens. It is a pressure-driven barrier to only allow water and low molecular weight solutes pass through the membrane. Ultrafiltration is fundamentally same as microfiltration and nanofiltration, except in terms of the size of the molecules it retains. In general, it will remove anything-larger than10 nanometer.

Ultrafiltration is applied in cross-flow and undergoes concentration polarization, which the accumulation of particulates and retained colloids may form a concentrated gel layer. The gel-layer formation can significantly alter the ultrafiltration’s performance. Fundamentally, the gel layer will limit flow rate and any increase in pressure will have no beneficial effect. Controlling and reducing the gel-layer and micro organism formation can be achieved with a Selecto IC600+, IC614+, IC620+, or IC620+/2 with NanoSmart Technology filtration system. NanoSmart Technology is state of the art with NanoMetal Oxide incorporated with porous technology in radial flow.
