Nowadays, the use of porous ceramic technology to carry out in-depth treatment of water and gas to improve the degree of cleanliness has become a fairly mainstream method. In the field of water treatment, whether it is the treatment of urban sewage or industrial wastewater, or the purification of groundwater such as well water into domestic water or drinking water, ceramic membranes are widely used in various environmental projects by virtue of their excellent adsorption and environmental compatibility. A good application effect has been obtained. Ceramic membranes are mainly divided into three types: plate type, tubular type and multi-channel type. Among them, the hollow plate type ceramic membrane ranks first in the application of ceramic membranes due to its large filtration area, good chemical stability, acid and alkali resistance, and strong anti-microbial ability.
