High-Quality Ceramic UF Membrane for Water Purification Plant - China Suppliers and Factory
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.

🔬 Physical Sieving Function: 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
What is a ceramic UF membrane and what is it made of?
A ceramic UF membrane is an inorganic ultrafiltration membrane primarily made of aluminum oxide (Al₂O₃). It is engineered for water treatment systems and is designed to overcome the limitations of traditional organic membranes such as PVDF, PES, and PVC, offering superior durability and filtration performance.
How long does a ceramic UF membrane last compared to an organic membrane?
Ceramic UF membranes have a service life of above 5 years, significantly longer than organic membranes which typically last around 2 years. This extended lifespan reduces replacement costs and system downtime, making ceramic membranes a more economical long-term choice.
What is the filtration precision of ceramic ultrafiltration membranes?
Ceramic ultrafiltration membranes typically achieve a filtration precision of 0.01 to 0.02 micrometers (μm), equivalent to 10–20 nanometers. This pore size is smaller than most bacteria and viruses, enabling highly efficient removal of harmful contaminants and ensuring safe drinking water quality.
Why is ceramic UF membrane preferred over organic membrane for drinking water treatment?
Ceramic UF membranes are preferred because they are pollution-free, chemically stable, resistant to acid and alkali corrosion, and not susceptible to microbial degradation. Unlike organic membranes, they do not risk leaching micropollutants as they age, making them safer and more reliable for long-term drinking water applications.
What are the key components of a ceramic UF membrane module?
A complete ceramic UF membrane module consists of the ceramic UF membrane, programmable valve, flow meter, pressure sensor, meter, PLC control cabinet, slow release device, releaser, and supporting auxiliary machinery. These components work together to ensure automated, efficient, and stable operation of the water purification system.
What production capacities are available for the ceramic UF membrane modules?
The ceramic UF membrane modules are available in a range of production capacities from 1,000 m³/d to 5,000 m³/d, with overall dimensions and pipe connection sizes varying accordingly. Custom configurations are available to meet specific project requirements. All parameters provided are reference values based on tap water quality upgrading standards.
