Ultrafiltration (UF) is a separation process using membranes with pore sizes in the range of 0.01 to 0.1 micron. Typically, UF membranes will remove high molecular-weight substances, colloidal materials, and organic and inorganic polymeric molecules

In drinking water purpose: UF can be used for the removal of particulates and macro-molecules from raw water to produce potable water.
Protein Concentration : UF is used extensively in the dairy industry,fruit juice concentration, pretreatment of RO System.
