The desalted water treatment process generally refers to removing the weak electrolyte in the water while removing the strong conductive material in the water. The desalted water treatment process includes pure water desalination treatment and high salt wastewater treatment. 

With the development of China's industrialization, the continuous improvement of economic reforms, and the continuous improvement of people's living standards and medical standards, desalination applications are everywhere. The water consumption in the chemical industry, power plants, and health care industries has also increased year by year. However, the environmental pollution of industrial wastewater is becoming more and more serious, and it is difficult to handle. It also forces the desalination treatment technology to continuously develop and improve.
