In recent years, ultrafiltration membrane (UF) technology has received tremendous importance for concentration, purification and fractionation of various products in diverse fields such as food, medical, and biotechnological industries, paper industry, dairy industry, etc. Ultrafiltration uses a finely porous membrane to separate water and microsolutes from macromolecules and colloids. The average pore diameter of the membrane is 10 to 1000 Å or two nm to 10 nm.

A membrane can be described as a thin barrier between the two bulk phases and it is either a homogeneous phase or a heterogeneous collection of phases. The membrane is a permselective barrier that permits transport of some component but retains others. The flow of material across a membrane is kinetically driven by the application of pressure concentration, vapor pressure, hydrostatic pressure, electrical potential, or temperature.
