what is uf in water purifier

In a water purifier, UF stands for Ultra-filtration, which is a membrane-based technology used to purify water. It works without electricity and can eliminate larger molecules of bacteria, viruses, and fungus. UF technology uses hydrostatic pressure to force water through a semi-permeable membrane, retaining suspended solids and solutes of high molecular weight while allowing water and low molecular weight solutes to pass through. The pore size of the ultrafiltration membrane is responsible for determining the type and size of contaminants removed. UF systems are effective in reducing rust, sediment, chlorine taste and odor, bacteria, and other impurities larger than the pore size, but they do not remove dissolved minerals or chemicals. UF technology is often used in combination with other purification technologies, such as UV, to provide comprehensive water purification.
