NanoMem ceramic membrane filtration technology can be used to filter the solution before ion exchange in Tungsten Hydrometallurgy. Practice has proved that the use of ceramic membrane elements can obtain better filtration effect, and the turbidity of tungsten after treatment can be reduced to less than 1ntu. In addition, the ceramic membrane has good regeneration. After cleaning with acid and alkali, the flux can be restored to more than 98%. It can greatly shorten the production process and realize full automatic production.

Compared with many organic membranes, inorganic ceramic membranes have the advantages of high temperature resistance, stable structure, uniform pore size distribution, good chemical stability, not easy to be eroded by microorganisms, high mechanical strength and easy regeneration. This characteristic determines its wide application in water treatment.

In the process of wet process phosphoric acid production, the filter cloth is easy to wear due to calcium sulfate crystallization, iron aluminum salt precipitation, small fluosilicate particles and so on.

At present, physical coagulation and sedimentation is one of the mainstream methods to treat pulping wastewater in papermaking industry.

Inorganic ceramic membrane has many advantages, such as high separation efficiency, stable effect, good chemical stability, acid and alkali resistance, organic solvent resistance, bacteria resistance, high temperature resistance, pollution resistance, high mechanical strength, good regeneration perf
