Industrial nanofiltration membranes are high-performance membrane products used for industrial water treatment and liquid separation. These membranes usually use Nanofiltration (Nanofiltration) technology, which has a smaller pore size than traditional microfiltration and ultrafiltration, and can effectively remove tiny particles, organics, heavy metal ions, etc. from water, while retaining minerals and nutrients in the water. Industrial nanofiltration membranes are widely used in various industrial fields, including but not limited to:1. **Water treatment industry:** Used in the treatment of industrial water, wastewater recycling, desalination treatment, etc., which can be applied to electric power, pharmaceuticals, chemical industry, electroplating, etc.2. **Food processing industry:** Used in the concentration, separation, and desalination of beverages, fruit juices, dairy products, and other food products. 3. **Pharmaceutical industry:** Used in the Pharmaceutical raw materials for the separation and purification, concentration of pharmaceutical water and other processes. 4. **Chemical industry:** used for solution concentration, separation, purification and other processes. 5. **Electronic industry:** used for semiconductor manufacturing process of ultrapure water treatment. 6. **Electronic industry:** used for semiconductor manufacturing process of ultra-pure water treatment. 7. Industrial nanofiltration membrane usually has the advantages of high flux, high retention rate, good corrosion resistance, high mechanical strength, etc., which can meet the strict requirements of water quality and liquid purity in industrial production. Selection of suitable industrial nanofiltration membrane products can improve process efficiency, reduce production costs and protect product quality.
