China Suppliers Ceramic UF Membrane Factory for Water Purification in 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
What is a ceramic UF membrane and what material is it made from?
A ceramic UF membrane is an inorganic ultrafiltration membrane primarily made from aluminum oxide (Al₂O₃). It is developed based on traditional tubular and flat-sheet ceramic membrane technology and is widely used in water treatment systems for drinking water, food processing, and chemical industries.
How does ceramic UF membrane compare to organic membranes in terms of service life?
Ceramic UF membranes offer a significantly longer service life of above 5 years, compared to organic membranes (such as PVDF, PES, or PVC) which typically last only about 2 years. Ceramic membranes also provide higher flux rates (50–200 L/㎡.h vs. 15–50 L/㎡.h) and superior chemical and mechanical stability.
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), which is equivalent to 10–20 nanometers. This pore size is smaller than most bacteria and viruses, enabling highly effective and stable water purification.
What are the main advantages of using ceramic UF membranes in water purification plants?
Key advantages include: easy cleaning using a variety of chemical agents or compressed air, long service life (5+ years), high mechanical strength compatible with high/positive/negative pressure environments, strong resistance to acids, alkalis, and organic solvents, resistance to microbial attack, and simple dry storage requirements — making them a reliable and cost-effective solution for large-scale water treatment.
What does the water purification process flow look like when using ceramic UF membranes?
The typical process flow is: 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 the removal of suspended solids, colloids, bacteria, and viruses.
What production capacities are available for ceramic UF membrane modules?
Ceramic UF membrane modules are available in a range of standard sizes with production capacities from 1,000 m³/d up to 5,000 m³/d. The modules vary in overall dimensions, number of membrane elements (16 to 72 pcs), and membrane area (328 m² to 1,764 m²), allowing flexible configuration for projects of different scales. Custom configurations are also available based on specific project requirements.
