The ultrafiltration membrane removes organic contaminants, viruses, bacteria, cysts, etc. down to a size of 0.01 micron without requiring toxic chemical treatments. Ultrafiltration works by physical particle exclusion. Raw water is filtered under pressure through a high-technology hollow fibre membrane. Our units are predominantly Inside-Out flow configuration, with the option of forward flushing the membrane. This reduces the incidence of membrane fouling and allows for high solids loading, high flow area and easy cleaning.
