Description

Technical Field

[0002] Plate ceramic membrane is an asymmetric membrane made of inorganic materials such as silicon carbide and aluminum oxide through a special process. The suspended materials in the slurry are adsorbed on the plate ceramic plate under the action of negative pressure. The solid particulate materials cannot pass through the micropores of the ceramic plate and are retained on the surface of the ceramic plate. Under the action of vacuum pressure difference, the water passes through the micropores of the ceramic plate smoothly into the gas-liquid distribution device and is discharged, thereby achieving the purpose of separation, concentration and environmental protection. Plate ceramic membrane is widely used in the fields of mineral separation and sewage separation. Its manufacturing process is complex and the application environment is harsh. After long-term operation, the separation efficiency of plate ceramic membrane gradually decreases, and various tests are required to ensure the stability of the production process.
