Zirconia Ceramic Membrane (ZrO₂ Ceramic Membrane)

Zirconia ceramic membrane (ZrO₂ membrane) is a high-performance inorganic filtration membrane manufactured using zirconium oxide as the active separation layer.

Compared with conventional alumina ceramic membranes, zirconia membranes provide superior hydrophilicity, enhanced fouling resistance, and excellent chemical stability, making them particularly suitable for challenging separation processes involving high organic loads, oil-containing wastewater, and high-value product recovery.

The asymmetric membrane structure consists of:

• Mechanical support layer
• Intermediate transition layer
• Zirconia separation layer

With precisely controlled pore size distribution, zirconia ceramic membranes provide stable filtration performance for microfiltration (MF) and ultrafiltration (UF) applications.

The naturally hydrophilic surface of ZrO₂ reduces organic adsorption and membrane fouling, enabling longer operation cycles.

Zirconia membranes withstand:

• Strong acids
• Strong alkalis
• Oxidizing agents
• Organic solvents

Suitable for aggressive industrial environments.

Uniform pore structure enables:

• Suspended solids removal
• Oil-water separation
• Protein concentration
• Catalyst recovery

Unlike polymer membranes, zirconia ceramic membranes tolerate:

• Chemical cleaning
• High-temperature sterilization
• Repeated regeneration cycles

• Oily wastewater
• Chemical wastewater
• Industrial wastewater recycling

• Juice clarification
• Dairy filtration
• Fermentation separation

• Protein concentration
• Biological product purification

• Catalyst recovery
• Solvent purification

Zirconia ceramic membranes provide an advanced solution for applications where conventional ceramic membranes suffer from rapid fouling or insufficient separation stability.

With excellent hydrophilicity, chemical resistance, and regeneration capability, ZrO₂ membranes are particularly suitable for demanding industrial filtration processes requiring long service life and stable performance.
