Silicon Carbide Ultrafiltration Ceramic Membrane

Silicon Carbide Ultrafiltration (UF) Ceramic Membranes are high-performance inorganic separation membranes designed for precision liquid filtration and advanced wastewater treatment. Manufactured from high-purity silicon carbide (SiC) through advanced ceramic processing and high-temperature sintering, these membranes feature a multi-layer asymmetric structure that combines exceptional permeability with outstanding mechanical durability.

With pore sizes ranging from 2 nm to 100 nm, silicon carbide ultrafiltration membranes provide highly efficient separation of fine particles, colloids, macromolecules, emulsified oils, and suspended contaminants while maintaining extremely high permeate flux.

Compared with conventional polymeric ultrafiltration membranes, SiC UF membranes offer significantly higher permeability, lower fouling tendency, superior cleaning performance, and longer operational life. These characteristics make them particularly suitable for lithium battery manufacturing, semiconductor production, CMP wastewater recycling, and other demanding industrial separation processes.

The highly interconnected silicon carbide pore structure provides exceptionally high water permeability while maintaining precise ultrafiltration performance.

Benefits include:

• Higher production capacity
• Higher permeate flux
• Lower membrane area requirements
• Reduced operating costs

Compared with conventional ceramic and polymer ultrafiltration membranes, silicon carbide membranes achieve higher permeability at the same filtration accuracy.

Higher permeability results in:

• Increased system productivity
• Lower transmembrane pressure (TMP)
• Reduced pumping energy
• Improved overall process efficiency

The naturally hydrophilic silicon carbide surface minimizes contaminant adhesion and significantly reduces membrane fouling.

Advantages include:

• Slower flux decline
• Longer filtration cycles
• Reduced cleaning frequency
• Stable long-term operation

These characteristics are particularly important for wastewater streams containing fine particles and organic contaminants.

The rigid ceramic structure provides excellent resistance to:

• Abrasive particles
• Pressure fluctuations
• Continuous operation
• Mechanical impact

This ensures reliable performance in demanding industrial environments.

Silicon carbide membranes tolerate aggressive cleaning procedures without damaging the membrane structure.

Cleaning methods include:

• Acid cleaning
• Alkali cleaning
• Oxidant cleaning
• High-pressure backwashing
• Chemical Cleaning-in-Place (CIP)

The excellent cleanability enables rapid flux recovery and minimizes system downtime.

Compared with polymeric ultrafiltration membranes, SiC ceramic membranes provide:

• Longer operational lifetime
• Higher wear resistance
• Stable filtration performance
• Lower replacement frequency

This significantly reduces total lifecycle costs.

Standard ultrafiltration pore sizes include:

• 2 nm
• 5 nm
• 10 nm
• 20 nm
• 50 nm
• 100 nm

Custom pore sizes are available for specialized separation applications.

Silicon carbide ultrafiltration ceramic membranes are widely used in high-value industrial processes requiring precise particle removal and stable long-term operation.

Suitable for removing fine suspended solids, metal hydroxides, graphite particles, and cathode material residues from lithium battery production wastewater, enabling water recycling and resource recovery.

Efficiently separates valuable battery materials from production process streams, improving raw material utilization and reducing waste.

Provides reliable removal of ultra-fine particles and colloidal contaminants generated during semiconductor manufacturing processes.

Ideal for Chemical Mechanical Planarization (CMP) wastewater treatment, removing silica slurry, polishing particles, and other fine contaminants before water reuse.

Designed for precision filtration of:

• Fine colloids
• Metal oxides
• Nanoparticles
• Pigments
• Catalyst particles
• Process slurries

Supports advanced industrial water recycling systems requiring stable ultrafiltration performance and low membrane fouling.
