Select water treatment equipment according to water quality
The hardness of water quality is different in different areas. In the north of China and the south of limestone area, the content of calcium and magnesium ions in the water is high, and it is easy to scale. Therefore, the filter water purifier with ion exchange resin filter element should be selected. In the design of reverse osmosis system, pre-treatment such as quartz sand + carbon filter + water softener is designed, followed by ultrafiltration and reverse osmosis. In the south, the water treatment should be ultrafiltration first, and then reverse osmosis.
For the city tap water with heavy chlorine, heterochromatic odor and more organic matter in the water, the household water purifier with more activated carbon can be selected. Because activated carbon has adsorption effect on residual chlorine and heterochromatic peculiar smell in water, it has obvious removal effect on organic matters.
For the purification of the turbid tap water in urban and rural areas, the household water purifier with the functions of coarse filtration and fine filtration should be selected. Water pollution is serious. It is required to thoroughly filter out bacteria, viruses, heterochromatic odor, pesticides, heavy metals and other impurities in the water. If it is not necessary to heat and drink directly, reverse osmosis pure water machine shall be selected.
