What is a TDS controller in a Water Purifier? But first, what is the TDS in a water purifier? TDS- is Total Dissolved Solids in a water body. While certain amounts of minerals and their types are essential for the normal functioning of the human body, nonetheless, above the ‘healthy levels’ can be harmful to the natural health of any Human. Generally speaking, the TDS of any water body at a given point in time should be 50-150. However, a higher range than this will be rendered unfit for consumption. TDS value is measured in PPM or Parts Per Million. So, what is a TDS controller in a water purifier? And how does it affects the way we consume water? Let us find out more.

What Is TDS Adjuster In Water Purifier?
The TDS controller or the adjuster is a manual device that is used to ‘physically’ control the number of dissolved solids in drinking water. The TDS controller is used in a water purifying system, where the dangers of completely stripping off useful minerals can occur. On the flip side, one can also end up consuming excessive levels of Minerals in the drinking water, which can lead to health hazards.
The structure of the TDS controller comprises two water inputs and single water output. There is also present a Control screw or tap to control the flow of water as and when required. This ‘tap’ or screw fixture is situated on the two water input sources and needs to be adjusted in a manner that the TDS remains between 20-150 PPM.

How Does the TDS Controller Works?
The TDS controller works in the following manner:
Input 1: This is where the water from the RO membrane enters the TDS controller system.
Input 2: This is where the clean water from the Activated Carbon Filter enters the TDS controller system. The Activated Carbon filter is found in case you have a water purifying system: RO+ UV+TDS controller system.
The same pathway is followed, but the water enters the UF membrane in the case of the RO+UF+UV+TDS water purifier system.
Water Output: This is the place where the water from both Inputs 1 and 2 get together in the ‘healthy’ ratio to be consumed.
The TDS Screw: This is, in a way, the main aspect of the controller system where the TDS value of the water is adjusted accordingly as it emerges from the two inputs.
So, in a way, if you need to reduce the TDS value, you will have to;
Increase the flow of the input water emerging from the RO membrane along with the decrease in the flow of water input emerging from the Activated Carbon Filter or the UF membrane accordingly.
In case you need to Increase the TDS value, you will have to:
The water flow from the Input of the RO membrane needs to be decreased, and the water input from the Activated Carbon Filter or UF membrane needs to be increased.
What Is The Use Of a TDS Controller In a Water Purifier?
The benefits of the application of the TDS controller in a water purifier are plenty and quite relevant. As one might know, the natural water body comprises various basic minerals like magnesium and calcium, also known as essential minerals. This implies the fact that these minerals are essential for the healthy working of the human body. Likewise, there are also present various harmful minerals like Arsenic, Fluorides. These are also known as heavy metals or harmful minerals. So these harmful dissolved solids lead to the health hazards one is concerned about. The levels or the amount of these harmful solids is what constitutes the TDS level of any water body.
While the RO membrane is known to eliminate 90% of harmful minerals from the water body, nevertheless, this reaches a limit when the TDS levels are too high. This is where the TDS controller in the water purifier comes into play. The RO membrane and the TDS controller work together to ‘maintain’ the normal healthy level of the TDS in the drinking water.
Is It Recommended to Buy the TDS controller?
As mentioned earlier, one might consider purchasing a TDS controller only when:
- The TDS levels are much low: < 900 PPM.
- The water is devoid of heavy metals like Arsenic and Lead.
If the above two criteria are not met, it is recommended to opt for a Mineralizer instead of a TDS controller.
What to Choose?
Here is a simple table for you to consider if you are confused about certain facts:
TDS LEVELS | IS THE WATER BODY MUDDY? | THE BIOLOGICAL BODIES PRESENT | THE RECOMMEDED CHOICE |
500-900 PPM | No | No | TDS+RO+Controller/Mineraliser |
500-900 PPM | No | Yes | RO+UV+TDS controller/Mineraliser |
500-900 PPM | Yes | No | UV+RO+UF+TDS controller/Mineraliser |
500-900 PPM | Yes | Yes | UV+RO+UF+ Controller/Mineraliser |
>900 PPM | No | No | RO |
>900 PPM | No | No | RO+ UV |
>900 PPM | Yes | No | UF+RO, UV+RO+UF |
>900 PPM | Yes | Yes | RO+ UV + UF |

What is a Mineralizer?
There are certain limits to utilizing the TDS controller in aquaguard or the RO Purifier. This is because there are certainly useful and healthy minerals like Calcium and Magnesium that are also eliminated from the water during the purification process. This is because the RO membrane cannot distinguish between good minerals and bad minerals. Hence, there is a fat chance that you are drinking ‘dead water’ altogether. So what do you do? Well, simply get yourself a Mineralizer in this case.
The Mineralizer is a device that helps return the essential minerals into the drinking water. It also helps in retaining the balanced PH value of the water in order to make it fit for normal consumption. This simple device, also known as the Mineral cartridge, allows the water to pass through itself, infusing it with the required minerals in the process as it emerges from the other end.

What Is A Tds Controller In A Water Purifier?: The Conclusion
Healthy drinking water is the very basis of overall good health, and one must understand the very component that comprises the good health of drinking water. For this, the RO membrane is insufficient in certain cases of higher TDS. So, a TDS controller comes to play. Do not be shy about investing in a proper water purifying system, as it is worth every dime you spend.
