Ultra filtration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the permeate (filtrate). This separation process is used in industry and research for purifying and concentrating macromolecular solutions, especially protein solutions. Ultra filtration is not fundamentally different from microfiltration. Both of these separate based on size exclusion or particle capture. It is fundamentally different from membrane gas separation, which separate based on different amounts of absorption and different rates of diffusion. Ultra filtration membranes are defined by the molecular weight cut-off (MWCO) of the membrane used. Ultra filtration is applied in cross-flow or dead-end mode.

Ultra filtration (UF) is a water purification method that involves forcing water through a semipermeable membrane. Suspended particles and high-molecular-weight solutes remain on the retentate side of the membrane, whereas water and low-molecular-weight solutes pass through to the permeate side.
UF can remove the majority of organic compounds and viruses, as well as a variety of salts. It has grown in popularity since it produces consistent water quality regardless of the source water, has a small physical footprint, removes 90-100% of pathogens, and does not require chemicals, with the exception of membrane maintenance.
Ultrafiltration (UF) is a highly efficient method of removing suspended particles, endotoxins, bacteria, viruses, and other pathogens from feed water, resulting in high-purity water.
Ultrafiltration is used to pre-treat surface water, seawater, groundwater, and biologically treated effluent before proceeding to membrane demineralization systems such as nanofiltration and reverse osmosis.
Ultrafiltration maintains water quality regardless of the total suspended solids (TSS) in the feed water. It lowers organic debris by 50-90 percent and, with the addition of coagulants, can be used to remove arsenic. It also effectively eliminates germs.
