A Review On Ceramic Membrane

The use of membrane technology in various processes of processing materials is increasing and the use of this technology in the water and sewage industry is also expanding. Ceramic membranes are one of the types of membranes used in recent years in the field of water and wastewater. These membranes can be replaced by micron filters because of their physical structure and pore size. These membranes have more thermal resistance and also corrosion resistant. Ceramic membranes are made by combining metals such as aluminum, titanium, calcium and ... with a non-metal in the form of nitrite or carbide oxide. Ceramic membranes made from such materials are the most important group of inorganic membranes. Aluminum oxide and zirconium oxide are among the most important materials in this group. The porous ceramic membrane configuration is mainly composed of three types: flat sheet, tube type and multi-channel, and plastic membrane is mainly used for small industrial production and laboratory research. The membrane is combined to form a tube heat exchanger, which can increase the membrane filling. However, due to the power problem, industrial applications have disappeared. The ceramic membrane of the scale program usually adopts a multichannel configuration setting, that is, several channels are distributed in a circular section, and the number of public channels is ۷, ۱۹, ۳۷, and so on[۱]. The main methods for producing ceramic membranes include preparation of solid particles, carrier membranes and microfiltration, ultrafiltration membranes and nanofiltration, using a glass membrane made from a divided phase, using a special technology (such as chemical vapor deposition and electrolysis coating, etc.)[۲].
