Zirconia Tubular Ceramic Membrane | Alumina-Supported ZrO₂ Membrane for High-Precision Crossflow Filtration
Product Details
Zirconia tubular ceramic membrane
,Alumina-supported ZrO₂ membrane
,High-precision crossflow filtration membrane
The Zirconia Tubular Ceramic Membrane features a high-purity zirconia (ZrO₂) separation layer supported by a robust alumina (Al₂O₃) porous substrate. This asymmetric multi-layer structure combines the exceptional separation performance of zirconia with the excellent mechanical strength of alumina, providing reliable filtration under demanding industrial conditions.
Manufactured through precision coating and high-temperature sintering, the membrane delivers a highly uniform pore structure with outstanding chemical resistance, thermal stability, and long-term durability. It is ideal for nanofiltration, ultrafiltration, clarification, concentration, and purification processes requiring high product purity and consistent performance.
The membrane consists of three functional layers:
- Porous Alumina Support Layer – Provides high mechanical strength and pressure resistance.
- Intermediate Transition Layer – Ensures strong bonding and uniform pore gradient.
- Zirconia Separation Layer – Delivers precise molecular-level separation with excellent chemical stability.
This asymmetric design optimizes both permeate flux and filtration accuracy while maintaining structural integrity during continuous operation.
- High-purity zirconia separation layer
- High-strength alumina support structure
- Uniform nanopore distribution
- Excellent separation efficiency
- Outstanding acid and alkali resistance
- Excellent resistance to organic solvents
- High thermal stability up to 300°C
- Smooth membrane surface for reduced fouling
- Compatible with chemical cleaning and steam sterilization
- Long operating life with stable filtration performance
The membrane operates using inside-out crossflow filtration.
Feed liquid enters the internal channels of the tubular membrane. Under transmembrane pressure, water and low-molecular-weight substances permeate through the zirconia separation layer, while suspended solids, bacteria, proteins, colloids, nanoparticles, and other larger components are retained inside the membrane channels.
The continuous crossflow velocity effectively minimizes membrane fouling and maintains stable permeate flux during long-term operation.

The zirconia separation layer provides an extremely narrow pore size distribution, enabling efficient removal of bacteria, proteins, colloids, nanoparticles, and other fine contaminants while maintaining high permeate quality.
The porous alumina support offers excellent compressive strength and structural stability, allowing the membrane to withstand high operating pressures and repeated cleaning cycles.
The zirconia membrane surface maintains excellent resistance to strong acids, alkalis, oxidizing agents, and many organic solvents, making it suitable for aggressive process environments.
The dense and smooth zirconia surface minimizes contaminant adhesion and biofilm formation, extending filtration cycles and reducing cleaning frequency.
The inorganic ceramic construction allows repeated chemical cleaning, high-pressure backwashing, and thermal sterilization without significant degradation, resulting in lower lifecycle costs than polymer membranes.
