《Silicon Carbide Ceramic Membrane for High Standard Drinking Water Applications》

General Manager Zhang Yunfei made a detailed introduction around the pain points of high-standard drinking water treatment, combined with the advantages of silicon carbide ceramic membrane and classic cases. Silicon carbide ceramic membrane is made of silicon carbide, with excellent filtration performance, strong chemical stability, material safety, good anti-pollution, etc. It has been widely used in domestic and international drinking water purification projects, including urban water purification, agricultural drinking water treatment and reclaimed water treatment, etc. In addition, there is a significant breakthrough in the purification of new pollutants PFAS/PFOS, and the product is used in the renovation of a water plant in the state of Tennessee (scale 3.87 million tons/day), which plays a role in global drinking water safety guarantee. （The products are used in the renovation of a water plant in Tennessee, U.S.A. (scale: 38,700 tons/day), which plays an important role as a model for global drinking water safety.

The advantages of silicon carbide ceramic membrane in high standard drinking water:

1. Excellent water quality: turbidity <0.1NTU, microbial removal rate of 99.999%, up to the standard of drinking water and some indicators are better than those in Europe and the United States.

2. Long service life: 2400 ℃ recrystallization of sintered silicon carbide material, life expectancy of more than 20 years under normal working conditions.

3. Short process and land saving: abandon the long process, process simplification, equipment standardization, short construction cycle.

4. Strong shock load resistance: when the quality of raw water fluctuates drastically (such as rainstorms, floods), it can still guarantee that the water is stable and meets the standard.

5. Safe and environmentally friendly materials: no heavy metals, microplastics, PFAS dissolution, low energy consumption, green and low-carbon.

Looking Ahead - A New Chapter

The National Water Science and Technology Conference has set up an efficient communication and cooperation platform for the field of water science and technology, gathering wisdom from all sides and consolidating development consensus. The in-depth discussions and achievements of many experts and enterprise representatives have strongly promoted the deep integration of industry, academia and research, and accelerated the transformation and application of scientific and technological innovations. I believe that under the joint efforts of all parties, China's water science and technology industry will continue to break through the innovation, water pollution prevention and control, water resources protection and utilization and other aspects of greater progress, in order to achieve a harmonious coexistence of man and nature in the Chinese modernization to contribute to more power, open a new chapter in the development of water industry innovation.
