Zirconia Tubular Ceramic Membrane is manufactured using high-purity zirconia (ZrO₂) as the separation layer on a robust ceramic support through precision sintering technology. Its highly uniform nanoporous structure provides exceptional separation accuracy while maintaining excellent permeability and chemical stability.

Designed for demanding filtration processes, zirconia ceramic membranes are particularly suitable for pharmaceutical manufacturing, biotechnology, fine chemicals, electronic chemicals, protein concentration, enzyme purification, and solvent-resistant filtration applications where high product purity and stable long-term performance are essential.

Compared with conventional polymer membranes, zirconia ceramic membranes offer superior resistance to harsh chemicals, high temperatures, and aggressive cleaning procedures while delivering a significantly longer service life.

• Ultra-fine separation down to nanometer scale
• Highly uniform pore size distribution
• Excellent chemical resistance to acids, alkalis and solvents
• Outstanding thermal stability up to 300°C
• High mechanical strength and pressure resistance
• Smooth membrane surface with excellent anti-fouling performance
• Stable permeate flux during continuous operation
• Compatible with high-pressure backwashing and CIP cleaning
• Long service life with low maintenance requirements
• Customizable pore sizes and membrane dimensions

The Zirconia Tubular Ceramic Membrane operates using an inside-out crossflow filtration process.

Feed liquid flows at high velocity through the membrane channels. Solvents and low-molecular-weight components permeate through the zirconia separation layer, while suspended solids, microorganisms, colloids, proteins, enzymes, and other larger molecules are retained inside the membrane channels.

Continuous crossflow minimizes cake layer formation and significantly reduces membrane fouling, ensuring stable filtration performance over extended operating periods.

Custom dimensions and channel configurations are available upon request.

The membrane can be integrated into customized filtration systems with various housing materials.
