Ground water (water for bore wells, tube wells) typically has high TDS unlike surface waters (water from rivers, lakes, reservoirs, ponds), which have low TDS but may contain suspended and microbiological impurities. Ground water with high TDS can be effectively treated with an RO system while surface waters can use a well-designed 3 stage UV system for effective purification.
Total Dissolved Solids (TDS): TDS is composed of inorganic salts & small amounts of organic substances which are dissolved in water. For example, excess of calcium and magnesium salts in water make it hard.
Safe levels of TDS for human body is under 500 PPM(this can be checked with a simple TDS meter). If TDS is above 500 PPM, then there is a need to use RO technology to bring the levels down, to safer levels. High levels of TDS over prolonged periods (several years)may create health problems such as gall bladder
and kidney stones. On the contrary, it’s important to know that drinking water devoid of any TDS and mineral content is also harmful to the body and creates health issues in the long run.
