In addition to water treatment, membrane filters can also be used for ultra-pure water production and desalination.
Generally, reverse osmosis membranes (nanofiltration membranes) are used. Ultrafiltration membranes and microfiltration membranes are commonly used in the treatment of feces and urine, urban sewage and various wastewater. In industry, it can be used in dairy products manufacturing, semiconductor manufacturing, food manufacturing, paper manufacturing, and pharmaceutical manufacturing. Ultrafiltration membranes and microfiltration membranes are also commonly used.
membrane filters are used in food and beverage, medical pharmaceuticals, municipal industrial water treatment, industrial high purity water, boiler water supply, seawater desalination, ultra-pure water in electronic industry, wastewater treatment and reuse, material concentration and purification and other industries.
More extensive, household ultrafiltration water purifier, ultrafiltration membrane. It can remove macromolecules, colloids, proteins, and particles in solution, and has the characteristics of low pressure, large water production, and easy operation.
Application of membrane filters in Wastewater Treatment
It has been applied to the treatment of paint spraying wastewater, metal processing wastewater, food industry wastewater and the recovery of useful substances in the automobile manufacturing industry. Ultrafiltration has good removal characteristics for all kinds of colloids in water, so it can be extended to the pretreatment of condensate water purification and ion exchange desalination system.
