4 Inch Low Pressure Reverse Osmosis Membrane 2400Gpd 150psi For RO Water Purifier Treatment
Water treatment refers to the physical and chemical measures taken to make the water quality meet certain usage standards. Minimum standards for drinking water are set by environmental protection authorities. Industrial water has its own requirements. The physical properties of water, such as temperature, color, transparency, odor, and taste, are the basic criteria for judging the quality of water quality. 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, in some grasslands, the concentration of total dissolved solids in natural water is as high as 1000 mg/L, while Canada stipulates that the concentration of total dissolved solids in drinking water should not exceed 500 mg/L, and many industrial water also requires that the concentration should not exceed 200 mg/L. This 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 is also an important characteristic that must be monitored.
