Industrial production lines in food, pharmaceutical, biological and fine chemical industries require high-purity process water with low conductivity, low impurity content and stable water quality. Traditional water treatment processes including sand filtration, activated carbon filtration and ion exchange cannot thoroughly remove soluble salts, tiny colloids and organic pollutants, resulting in unstable water quality, frequent resin regeneration and high operating costs. Reverse osmosis membrane technology relies on precise physical screening to effectively intercept inorganic salts, organic impurities, suspended colloids and microorganisms in raw water. It realizes efficient purification and desalination of source water under low-pressure and room-temperature conditions, stably producing qualified industrial pure water. With the advantages of low energy consumption, no chemical pollution and stable water quality, reverse osmosis has become the core technology for modern industrial pur
Concentrated milk is widely applied in dairy beverage, bakery and ice cream industries. Traditional concentrated milk production mainly adopts vacuum evaporation, which requires high-temperature operation, consumes massive steam and damages heat-sensitive flavor substances and nutrients in milk. Reverse osmosis membrane technology realizes low-temperature concentration of milk by selectively intercepting milk solids while allowing water molecules to permeate the membrane. It reduces the water content of raw milk under mild conditions, retains natural milk aroma and nutritional components, and significantly cuts energy consumption. This energy-saving membrane process has become an important auxiliary concentration technology for modern concentrated milk manufacturing.
Raw milk collected from dairy farms contains complex heterogeneous components including somatic cells, residual bacteria, microscopic dust, colloidal protein aggregates and uneven fat globules. Traditional milk purification relies on pasteurization, centrifugal degreasing and precision filtration, which cannot completely remove micro-impurities and often cause damage to natural milk flavor and active nutrients. Conventional thermal treatment also fails to standardize milk composition, resulting in unstable taste and quality differences between production batches. Cross-flow ultrafiltration membrane technology achieves low-temperature physical purification, bacterial removal and ingredient standardization of raw milk under mild operating conditions. It effectively eliminates microorganisms and micro-colloidal impurities while completely retaining natural milk nutrients and original flavor. This advanced physical processing method greatly improves milk safety, purity and product consiste
