High-Quality Ceramic UF Membrane for Water Purification from China Suppliers & 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.

💧 Core 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 (FAQ)
What is a ceramic UF membrane and what is it made of?
A ceramic UF (ultrafiltration) membrane is an inorganic membrane made primarily of Al₂O₃ (aluminum oxide). It is used in water treatment systems and developed as an advanced alternative to traditional tubular and flat-sheet ceramic membranes, offering superior durability and filtration performance.
What are the main advantages of ceramic UF membranes over organic membranes?
Ceramic UF membranes offer several key advantages over organic membranes (such as PVDF, PES, PVC): a longer service life (5+ years vs. ~2 years), higher flux (50–200 L/㎡.h), strong resistance to acid, alkali, and organic solvents, resistance to microbial attack, easier cleaning with compressed air or various chemical agents, and simpler dry storage requirements.
What is the filtration precision of ceramic ultrafiltration membranes?
Ceramic UF 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 suspended solids, colloids, and other harmful substances from water.
What is the typical process flow in a ceramic UF membrane water purification plant?
The standard process flow is: High-level drinking water source → Chemical dosing and flocculation → High-level sedimentation and filtration tower → Self-cleaning filter → Ceramic UF membrane module → Disinfection → Water storage tank → External pump → End user. This multi-stage process ensures safe and high-quality drinking water output.
