Ultra Filtration Plant is a pressure-driven barrier to suspended solids, bacteria, viruses, endotoxins and other pathogens to produce water with very high purity and low silt density. Typically, ultra filtration will remove high molecular-weight substances, colloidal materials, silt (SDI), and organic and inorganic polymeric molecules.
It serves as a pretreatment for surface water, seawater and biologically treated municipal effluent before reverse osmosis and other membrane system. UF works on low pressures ( range from 1 to 10 bar). Hallow fibre or spiral wound membranes are used for the construction of UF plant.
MEMBRANE BASED FILTRATION SYSTEM
ULTRA FILTRATION (UF)
Ultra Filtration (UF) is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semi permeable membrane.Suspended solids and solutes of high molecular weight are retained, while water and Low molecular weight solutes pass through the membrane.This separation process is used in industry and research for purifying and concentrating macromolecular (103-106 Da) solutions, especially protein solutions..
