Ceramic membrane is made of inorganic materials, and its precision can reach the level of microfiltration and ultrafiltration. Organic membrane is made of organic materials, and its precision can reach the level of microfiltration, ultrafiltration, nanofiltration, reverse osmosis. Why organic membrane can not completely replace Ceramic membrane, or Ceramic membrane can not completely replace organic membrane, mainly depends on the applicability of materials. Ceramic materials are preferred for filtration with high material turbidity and solid content. The material is clear and has good solubility. Choosing an organic membrane has low cost per unit membrane area, fast filtration flux, and generally uses organic membranes for fine separation and purification. Organic material cleaning generally requires gentle conditions, and ceramics can withstand strong acid and alkali cleaning. The existence of different membranes is reasonable, mainly depending on the selection of equipment and membrane components that are suitable for your material. It is necessary to choose the appropriate one to better match the process conditions, making production smoother, production costs lower, and product quality higher.
