China Ceramic UF Membrane Suppliers - High-Quality Water Purification Factory for Drinking Water Treatment
Description
Ceramic membrane is inorganic ultra-filtration membrane made of Al₂O₃, which used for water treatment system developed based on traditional tubular and flat-sheet ceramic membrane. 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 industry.
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 the tap water requirement, the traditional ultrafiltration membranes which produced from organic material such as PVC, PE, PDFE, etc are hard to be compatible as the risk of leakage of micropollutants after filter system aging. To instead, ceramic UF membrane becomes more and more popular.

Frequently Asked Questions (FAQ)
Q What material is the ceramic membrane made of?
The ceramic membrane is an inorganic ultra-filtration membrane made of high-quality aluminum oxide (Al₂O₃), designed specifically for advanced water treatment systems.
Q How does the lifespan of a ceramic membrane compare to an organic membrane?
Ceramic membranes offer a significantly longer service life of above 5 years, compared to organic membranes (PVDF, PES, PVC) which typically last for about 2 years.
Q What is the filtration precision of the ceramic UF membrane?
The ceramic ultrafiltration membrane features a filtration precision between 0.01 and 0.02 micrometers (10-20 nanometers), allowing it to effectively block bacteria, viruses, and suspended solids.
Q What are the cleaning advantages of using ceramic membranes?
Unlike organic options, ceramic membranes are compatible with a wide variety of chemical cleaning agents and can also undergo high-impact cleaning with compressed air without risk of damage.
Q How does the recommended flux compare between inorganic and organic membranes?
Ceramic membranes support a much higher recommended flux range of 50 to 200 L/㎡.h, whereas organic membranes are limited to a lower flux range of 15 to 50 L/㎡.h.
Q Are ceramic membranes resistant to chemical and microbial attacks?
Yes. Ceramic membranes possess excellent chemical stability, making them highly resistant to acid, alkali, organic solvents, and microbial decomposition.
