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