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, PVDF, etc. are hard to remain compatible due to the risk of micropollutant leakage after filter system aging. As a result, ceramic UF membranes are becoming increasingly popular.

❓ Frequently Asked Questions
Q
What is a ceramic UF membrane and what is it made of?
A ceramic UF (ultrafiltration) membrane is an inorganic filtration membrane made primarily of aluminum oxide (Al₂O₃). It is designed for water treatment systems and is used as an advanced alternative to traditional organic membranes (such as PVDF, PES, and PVC). Its inorganic nature gives it superior chemical stability, mechanical strength, and a significantly longer service life.
Q
How does the filtration precision of a ceramic UF membrane compare to bacteria and viruses?
Ceramic UF membranes typically have a filtration precision of 0.01 to 0.02 micrometers (μm), equivalent to 10–20 nanometers. Since most bacteria range from 0.5–5 μm and viruses from 0.02–0.3 μm, the ceramic membrane's pore size is small enough to effectively block and remove these pathogens, ensuring highly safe and clean drinking water.
Q
What are the main advantages of ceramic membranes over organic membranes?
Ceramic membranes offer several key advantages over organic membranes: a service life of over 5 years (vs. ~2 years for organic), a much higher recommended flux (50–200 L/㎡·h vs. 15–50), resistance to acid, alkali, and organic solvents, resistance to microbial attack, compatibility with a wide range of chemical and compressed-air cleaning methods, and simple dry storage requirements. They are also pollution-free, unlike organic membranes which may release micropollutants as they age.
Q
What is the typical water treatment process using ceramic UF membranes?
The standard water purification process using ceramic UF membranes follows these steps: High-level drinking water source → Chemical dosing and flocculation → High-level sedimentation and filtration tower → Self-cleaning filter → Ceramic ultrafiltration membrane module → Disinfection → Water storage tank → External pump → End user. This multi-stage process ensures thorough removal of contaminants before water reaches consumers.
Q
What production capacities are available for ceramic UF membrane modules?
Ceramic UF membrane modules are available in a range of standard sizes to suit different production needs. The available configurations support daily production capacities of 1,000, 2,000, 3,000, 4,000, and 5,000 m³/day, with membrane areas ranging from 328 m² up to 1,764 m² and membrane counts from 16 to 72 pieces per module. Custom configurations may also be available upon request.
Q
In which industries can ceramic UF membranes be applied?
Ceramic UF membranes are suitable for a wide range of applications due to their excellent chemical and mechanical properties. Primary applications include municipal drinking water treatment, food and beverage processing, chemical industry filtration, industrial wastewater recycling, and any process requiring reliable removal of suspended solids, colloids, bacteria, and viruses. Their oil resistance and acid/alkali tolerance make them especially valuable in demanding industrial environments.
