Titania Tubular Ceramic Membrane

The Titania Tubular Ceramic Membrane features a high-purity titanium dioxide (TiO₂) separation layer supported by a porous alumina (Al₂O₃) substrate. This asymmetric multi-layer structure combines the excellent mechanical strength of alumina with the superior hydrophilicity and chemical stability of titania, delivering reliable filtration performance under demanding industrial conditions.

Manufactured through precision coating and high-temperature sintering, the membrane offers a highly uniform pore structure, stable permeate flux, and excellent resistance to harsh chemical environments. It is suitable for crossflow filtration, clarification, concentration, purification, and solid-liquid separation across pharmaceutical, biotechnology, food processing, chemical manufacturing, and water treatment industries.

The membrane consists of three functional layers:

• Porous Alumina Support Layer – Provides excellent mechanical strength and pressure resistance.
• Intermediate Transition Layer – Ensures strong interfacial bonding and a smooth pore-size gradient.
• Titania Separation Layer – Provides precise filtration, high hydrophilicity, and excellent chemical stability.

This asymmetric structure improves both filtration efficiency and membrane durability while maintaining stable performance during continuous operation.

• Low fouling tendency
• Suitable for repeated chemical cleaning and backwashing
• Long service life
• Customizable pore sizes and membrane dimensions

The Titania Tubular Ceramic Membrane operates using an inside-out crossflow filtration process.

Feed liquid flows through the internal channels of the membrane under pressure. Water and low-molecular-weight substances permeate through the titania separation layer, while suspended solids, bacteria, colloids, proteins, emulsified oils, and larger particles are retained within the membrane channels.

Continuous crossflow effectively minimizes cake layer formation and membrane fouling, ensuring stable filtration performance and long operating cycles.

• Excellent Hydrophilicity

  The naturally hydrophilic TiO₂ membrane surface promotes rapid wetting and stable water permeability, helping to maintain high filtration efficiency throughout continuous operation.

• High Flux Performance

  The optimized pore structure provides an excellent balance between filtration precision and permeate flux, reducing energy consumption and improving overall process productivity.

• Outstanding Chemical Resistance

  The membrane performs reliably under acidic, alkaline, and oxidizing environments and is compatible with a wide range of industrial cleaning chemicals.

• Superior Mechanical Strength

  The alumina support layer provides excellent compressive strength and structural stability, allowing the membrane to withstand high operating pressures and repeated cleaning cycles.

• Reduced Fouling

  The smooth hydrophilic membrane surface minimizes contaminant adhesion, helping extend filtration cycles and reduce maintenance frequency.

• Long Service Life

  The inorganic ceramic structure resists thermal aging, swelling, and chemical degradation, allowing repeated regeneration through chemical cleaning and high-pressure backwashing.
