Ultrafiltration (UF) membranes are a pressure-driven membrane separation technology based on the principle of physical sieving. The core of it is to retain colloids, bacteria, and large organic molecules while allowing water and small molecules to pass through. It is widely used in water treatment, food, medicine, environmental protection and other fields.
Water Treatment (Largest Application Area)
Municipal Water Supply: Pre-treatment at waterworks, replacing sand filters, removing turbidity, colloids, and bacteria, improving taste and safety.
Drinking Water Purification: Household/commercial water purifiers, rural water improvement, mineral water production, retaining minerals, sterilizing and removing turbidity.
Advanced Wastewater Treatment and Reuse: Core component of MBR, upgrading municipal/industrial wastewater standards, reclaimed water for landscaping, roads, and industrial cooling.
Industrial Pure Water/Ultrapure Water: Pre-treatment before RO in the electronics, semiconductor, and pharmaceutical industries, ensuring end-use water quality.
Industrial Wastewater Treatment: Circulating water in printing and dyeing, papermaking, chemical, electroplating, steel, and power plants, reusing resources and achieving compliant discharge.
