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:
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:
Suitable for aggressive industrial environments.
Uniform pore structure enables:
Unlike polymer membranes, zirconia ceramic membranes tolerate:
