Ultra Filtration Plant is a type of water filter membrane filtration in which hydrostatic pressure forces fluid against semipermeable membranes. Semipermeable membrane is a thin layer of material capable of separating substance when driving force is applied across the membrane. Once considered a viable technology for desalination only, the membrane process is increasingly used to remove bacteria and other microorganisms, particulate materials, and natural organic matter, which can give color, taste, and odor to water and react with disinfectants to form the by-products of disinfection.
