Ceramic Membrane Structure
Apr 13, 2018

Ceramic membrane is one of the inorganic membranes, belongs to the membrane separation technology of solid membrane materials, mainly for different sizes of alumina, zirconia, and titanium oxide and silicon oxide and other inorganic ceramic materials as support, the surface coating, high temperature burn becomes. Commercialization of ceramic membrane usually has a three layer structure (porous support layer, transition layer and separation layer), the asymmetric distribution of the aperture size of 0.8 nm ~ 1 mu m range, filtration precision include microfiltration, ultrafiltration, nanofiltration level.

According to the different supporting body, the configuration of ceramic membrane can be divided into three types: plate, tube and multi-channel. Ceramic membrane due to acid and alkali resistance, high temperature and chemical stability under extreme conditions, and as a result of the commercialization of ceramic membrane pore size is small (usually less than 0.2 microns), molecular level is achieved successfully with the filter, so it is mainly used for to filtration separation, liquid and gas mixture can replace the traditional centrifugal, evaporation, distillation, filtration, such as separation technology, improve product quality, reduce production cost goal, in harsh environments, such as petroleum and chemical industry has extensive application prospect.
