Introduction To Water Treatment

Water treatment refers to the physical and chemical measures taken to make the water quality meet certain usage standards. The minimum standard for drinking water is set by the environmental protection department. Industrial water has its own requirements. Physical characteristics such as temperature, color, transparency, smell, and taste of water are the basic criteria for judging the quality of water. The chemical properties of water, such as its pH, dissolved solids concentration, and oxygen content, are also important criteria for judging water quality. For example, the concentration of fully dissolved solids in the natural water of some grasslands is as high as 1000 mg/L, while Canada stipulates that the concentration of fully dissolved solids in drinking water shall not exceed 500 mg/L, and many industrial waters also require the concentration not to exceed 200 mg/L. This kind of water, even if its physical properties meet the requirements, cannot be used casually. In addition, the content of radioactive elements from nature, nuclear accidents and nuclear power plants, etc., is also an important characteristic that must be monitored.
