TDS value can't judge water quality. TDS value can't judge water quality. According to the new edition of Hygienic Standard for Drinking Water, there are 106 indicators in the first-class standard of tap water, and TDS value is only one of them. The safety range of tap water standard is required to be within 1000mg/l/L, and there are 106 indicators for water quality testing. TDS is one of these indicators, and it is not the most important indicator. TDS value can only measure the number (conductivity) of charged ions in water, and can only be used as the filtration purity of water purifier, and can not detect the safety of water quality.
TDS stands for the total amount of dissolved solids, indicating how many milligrams of dissolved solids are dissolved in 1 liter of water. The higher the TDS value, the more impurities are contained in the water, but these impurities cannot be detected, and beneficial natural minerals will also be classified as "impurities". In short, the TDS value is too low to say that water is healthy, but too high means there must be something wrong. The TDS value is between 1-40, which is most suitable for human consumption. /kloc-above 0/00, you can't drink it directly. It is recommended to drink it through reverse osmosis.
