Product Overview

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.

Key Features

Excellent Anti-Fouling Performance

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

Superior Chemical Resistance

Zirconia membranes withstand:

Strong acids
Strong alkalis
Oxidizing agents
Organic solvents

Suitable for aggressive industrial environments.

High Separation Efficiency

Uniform pore structure enables:

Suspended solids removal
Oil-water separation
Protein concentration
Catalyst recovery

Long Service Life

Unlike polymer membranes, zirconia ceramic membranes tolerate:

Chemical cleaning
High-temperature sterilization
Repeated regeneration cycles

Typical Applications

Wastewater Treatment

Oily wastewater
Chemical wastewater
Industrial wastewater recycling

Food & Beverage

Juice clarification
Dairy filtration
Fermentation separation
