Today, the editor will take you to understand the entire process of the development trend of inorganic ceramic membranes:

Ceramic film, also known as GT film, is an asymmetric dense film made from inorganic ceramic glaze through a unique processing technology, which is in the shape of a tube or multiple channels. The ceramic membrane wall is thick and covered with microporous plates. Under working pressure, the raw material liquid flows in the membrane tube or on both sides of the membrane. Small molecule water chemicals (or liquids) pass through the membrane, while large molecule substances (or solid particles, liquid liquids) are intercepted by the membrane to achieve solid-liquid separation, concentration, and purification.

Organic membranes were developed and designed earlier in the field of membrane technology advancement. These types of membranes are very easy to produce, easy to form, have excellent performance, and low price, and have become a commonly used type of hollow fiber membrane. However, with the development trend of membrane separation equipment and its application, higher and higher regulations have been put forward for the application standards of membranes. It is necessary to develop extreme standard membrane solid-liquid separation system software for new products. Compared with organic membranes, inorganic ceramic membranes have characteristics such as heat resistance, good organic chemical reliability, acid resistance, alkali resistance, solvent resistance, high impact toughness, reverse direction cleaning ability, strong ability to resist microbial strains, strong cleanability, narrow diameter distribution, large infiltration rate, high membrane flux, good separation performance, and long service life.

There are two key obstacles to the application of inorganic ceramic membranes in wastewater treatment. Firstly, the entire production process is complex, with increased costs and relatively high prices; The second issue is the difficulty of membrane flux. Only by eliminating membrane environmental pollution and improving membrane filtration flux can it be truly applied and promoted to various industries in wastewater treatment.
