Zirconia Flat Sheet Ceramic Membrane

Zirconia Flat Sheet Ceramic Membranes are manufactured from high-purity zirconium dioxide (ZrO₂) using advanced high-temperature sintering technology. Featuring an asymmetric ceramic membrane structure, they combine exceptional chemical stability, superior corrosion resistance, and excellent mechanical strength for demanding liquid separation applications.

Compared with alumina and titania ceramic membranes, zirconia membranes provide higher resistance to aggressive chemicals, making them the preferred choice for highly corrosive process streams, pharmaceutical manufacturing, fine chemical production, and high-purity filtration systems.

Designed for both microfiltration (MF) and ultrafiltration (UF), these membranes deliver stable filtration performance under harsh operating conditions while maintaining long service life and excellent cleanability.

Zirconia is one of the most chemically stable ceramic materials available.

The membrane offers excellent resistance to:

• Strong acids
• Strong alkalis
• Oxidizing agents
• Organic solvents
• High-salinity process fluids

Suitable for continuous operation in highly corrosive industrial environments.

The inorganic ceramic structure maintains excellent dimensional stability under elevated temperatures.

Benefits include:

• High thermal stability
• Excellent thermal shock resistance
• Stable pore structure
• Long-term performance under fluctuating operating conditions

Compared with conventional polymer membranes, zirconia ceramic membranes maintain excellent performance in severe chemical environments where polymeric membranes rapidly degrade.

Typical applications include:

• Chemical processing
• Electroplating wastewater
• Acid recovery
• Alkali recovery
• High-salt wastewater
• Semiconductor chemicals

The dense ceramic structure provides:

• Excellent compressive strength
• Outstanding wear resistance
• Resistance to pressure fluctuations
• Stable operation during repeated backwashing

Ideal for continuous industrial filtration.

Zirconia membranes tolerate aggressive cleaning methods, including:

• Strong acid cleaning
• Strong alkali cleaning
• Oxidative cleaning
• Hot water sterilization

allowing effective membrane regeneration and long operating life.

The precisely controlled pore structure enables reliable removal of:

• Suspended solids (SS)
• Fine particles
• Colloids
• Bacteria
• Macromolecules

while maintaining stable permeate quality throughout long operating cycles.

Zirconia Flat Sheet Ceramic Membranes are widely used in:

• Pharmaceutical process filtration
• Fine chemical production
• Semiconductor chemical filtration
• Electroplating wastewater treatment
• High-salinity wastewater
• Acid and alkali recovery
• Industrial wastewater treatment
• Water reuse systems
• High-purity liquid purification

Our Zirconia Flat Sheet Ceramic Membranes are engineered for applications where chemical stability and long-term reliability are critical. They offer:

• Exceptional resistance to highly corrosive chemicals
• Excellent durability under continuous industrial operation
• Long service life with minimal maintenance
• Superior cleaning and regeneration capability
• Stable filtration performance under extreme operating conditions
• Customizable pore sizes and module configurations

Whether used in pharmaceutical manufacturing, semiconductor processing, fine chemicals, or challenging industrial wastewater treatment, zirconia ceramic membranes provide reliable, high-performance filtration with lower lifecycle costs than conventional polymer membranes.
