When it comes to selecting a water purifier for home use or for commercial usage, there is always a confusion as to which technology is the best – RO or UV. However, to make a well-informed choice you need to, first, understand the difference between Groundwater and surface water. It is only when you understand the difference between these two types of water would you be able to pick a right water filter based on your needs.
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. Groundwater with high TDS can be effectively treated with reverse osmosis water filtration system a.k.a the RO water purifier while surface waters can use a well-designed 3 stage UV water purifier 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 water purifier 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. Now, based on the TDS level, you can either choose an RO or a UV water purifier. For those who need a UV water purifier check out this Ewater – UV home water purifier offered by Alfaa UV.
