OVER VIEW OF NANOFILTRATION CERAMIC MEMBRANE ELEMENT

Ceramic nanofiltration membrane is widely used in petroleum and chemical industry, medicine, metallurgy and other processes involving harsh systems due to its unique thermal stability and chemical stability, resistance to organic solvents, disinfection, regeneration, and backwashing. In the industrial field, ceramic membrane system has become one of the fastest growing and most promising membrane materials in the membrane field.

1. Nanofiltration technology

Nanofiltration membrane technology is a new type of pressure-driven separation technology between ultrafiltration and reverse osmosis. It can not only effectively separate the relative molecular mass of 200-1000 by sieving, but also generate the Donnan effect by electrostatic action, with high removal rate for divalent and high valence ions.

In recent years, nanofiltration technology has gradually occupied an important position in the petrochemical, food processing, wastewater treatment, medical technology, and energy industries, and is a common technology for achieving sustainable development.

2. Ceramic nanofiltration membrane

Nanofiltration membrane materials are a key core of nanofiltration technology. Ceramic nanofiltration membrane has excellent thermal stability, chemical stability, high mechanical strength, acid and alkali resistance, microbial erosion, chlorine and other oxidizing substances, anti-pollution, etc. It has become the fastest growing and most developed in the membrane field and one of the prospective membrane materials.
