In case you use water from a borewell in your house, the TDS content is likely to be significantly higher than that of the municipal water supply; therefore, an ordinary filter will not suffice.
However, if you have high TDS and borewell water in your area, then the combination of RO, UV, and UF purifiers are the best in India because while RO reduces the content of dissolved salts and metals, UV and UF take care of the microbial contaminants in the water.
Some of the latest models from brands like Pureit, Aquaguard, Aqua D Pure, Livpure, and Atomberg come with additional capabilities such as TDS controllers, copper, and alkaline enhancement.
Key Technologies: RO, UV, UF, and MF Explained for Indian Conditions
- RO (Reverse Osmosis): Forces water through a very thin membrane that prevents the entry of dissolved salts, heavy metals and hardness. This is the only process that lowers the TDS and therefore holds relevance to borewell water having high TDS.
- UV (Ultraviolet): These are ultraviolet radiation that are used to inactivate bacteria and viruses by destroying the DNA/RNA without physically eliminating them from water. The reason why UV does not lower the TDS is that it is never used alone but in combination with either RO or UF.
- UF (Ultrafiltration): Removes bacteria, cysts as well as other suspended solids by passing through a membrane that works without electricity. This is a process that does not lower TDS, and can be used in water that is naturally low in dissolved solids, such as municipal water.
- MF (Microfiltration): Responsible for removal of larger suspended solids and sediments as a supportive process.
For borewell water, the process that involves RO becomes very important because TDS removal is the stage that MF and UF cannot perform alone.
