Alumina Ceramic Membrane

Inorganic ceramic membranes are precision porous filtration materials fabricated from inorganic materials such as alumina (Al₂O₃), titanium oxide (TiO₂), and zirconium oxide (ZrO₂) through a high-temperature sintering process. They feature a three-layer asymmetric structure comprising a macroporous support layer, an intermediate transition layer, and a microporous separation layer. The filtration precision covers microfiltration, ultrafiltration, and fine pore sizes (down to ≥2 nm).

Tubular ceramic membranes predominantly employ a cross-flow filtration mechanism for fluid separation: the feed fluid flows at high velocity inside the membrane channels. Under the applied pressure, the permeate containing small molecules passes radially outward through the membrane separation layer, while the concentrate containing larger molecules is retained by the membrane, thereby achieving efficient fluid separation, purification, and concentration.

• Excellent Chemical Stability: Resistant to acids, alkalis, oxidants, and organic solvents.
• High-Temperature Resistance: Withstands high-temperature operation and autoclave sterilization.
• Easy Cleaning & Long Service Life: Provides a long operational lifespan with straightforward cleaning procedures.
• High Separation Precision: Features a narrow pore size distribution for highly accurate molecular separation.
• No Extractables: Free from extractable substances, making it highly suitable for food and pharmaceutical process separation.
• Compact System Footprint: Requires minimal installation space, features a high degree of automation, and reduces labor costs.
• Robust Feed Tolerance: Accommodates demanding or extreme feed conditions with minimal pre-treatment requirements.
• Highly Integrated Automation: The ceramic membrane system is highly integrated, enabling fully automated control and continuous feeding, simultaneous filtrate and retentate output.
• Enhanced Process Efficiency: Compared with traditional technologies, inorganic ceramic membrane separation increases product yield and purity, shortens production cycles, boosts economic returns, and contributes to energy savings and emission reductions.
