Ultra Filtration

Ultra Filtration (UF) is a type of membrane filtration in which hydrostatic pressure forces a liquid against a semi permeable membrane. A semi permeable membrane is a thin layer of material capable of separating substances when a driving force is applied across the membrane. Once considered a viable technology only for desalination, membrane processes are increasingly employed for removal of bacteria and other microorganisms, particulate material, and natural organic material, which can impart color, tastes, and odors to the water and react with disinfectants to form disinfection byproducts (DBP). As advancements are made in membrane production and module design, capital and operating costs continue to decline.

Advantages of Ultra Filtration:

• No need for chemicals (coagulants, flocculates, disinfectants, pH adjustment);Size-exclusion filtration as opposed to media depth filtration;
• Good and constant quality of the treated water in terms of particle and microbial removal;
• Process and plant compactness; and
• Simple automation.
