High-Quality Ceramic UF Membrane for Water Purification - China Suppliers and Factory Solutions
Description
Ceramic membrane is an inorganic ultra-filtration membrane made of Al₂O₃, which is used for water treatment systems developed based on traditional tubular and flat-sheet ceramic membranes. It effectively solves the technical defects found in the use of traditional ultrafiltration membranes (Organic membrane -- PVDF, PES, PVC) such as fiber breakage, membrane fouling, and membrane lifespan etc.
Its advantages of easy cleaning, long service life, high strength, oil resistance, strong acid/alkali resistance, and high flux make it a better choice for drinking water, food, and chemical industries.

In water treatment plants, the core function of ultrafiltration membranes is physical sieving. Like an "extra-fine sieve," it efficiently removes suspended solids, colloids, bacteria, viruses, and other harmful substances from the water with its extremely small pores, thereby significantly improving the safety and sensory quality of drinking water.
Along with the development of tap water requirements, traditional ultrafiltration membranes produced from organic materials such as PVC, PE, PDFE, etc., are hard to be compatible due to the risk of leakage of micropollutants after the filter system ages. Instead, the ceramic UF membrane is becoming more and more popular.
