Inorganic ceramic membrane is a ceramic filter material with a porous structure, which is sintered at high temperature, such as alumina, titanium oxide, and zirconia. The porous support layer, transition layer, and microporous membrane layer are asymmetrically distributed. Ultrafiltration and nanofiltration. Ceramic membrane filtration is a type of fluid separation process in the form of "cross-flow filtration": the raw material liquid flows at high speed in the membrane tube, and the clarified permeate containing small molecular components is driven through the membrane in a direction perpendicular to it under pressure. The turbid concentrated solution of macromolecular components is retained by the membrane, so that the fluid can achieve the purpose of separation, concentration and purification.
◆ Our advantages
The ceramic membrane based on the science of inorganic materials has some advantages that are incomparable with separation media such as plate and frame, centrifuge, diatomaceous earth and polymer membrane:
• Good chemical stability, resistant to acid, alkali and oxidation;
• Resistant to organic solvents and high temperatures;
• High mechanical strength and good abrasion resistance;
• Long life and large processing capacity;
• Narrow pore size distribution, extremely high separation accuracy, can reach nanometer filtration;
• Easy to clean, can be sterilized online or sterilized by high temperature, and can be reverse flushed.
Membrane Housing & Module
Ceramic membrane module
Membrane modules are pressure-resistant shells assembled with ceramic membrane elements. According to the needs of industrial production, centralized packing of ceramic membrane elements with different outer diameters and different areas can be achieved through membrane module shells of different specifications. The loading area of a single membrane module ranges from 0.02m 2 to 22m 2 . The shape design and seal design of the membrane module are very important for the operation of the ceramic membrane complete system.
