A TDS controller might be a known term. However, there is a mineralizer as well in water purifiers. Here is the difference between a TDS controller and a mineralizer (TDS Controller vs Mineralizer).
However, before getting into the differences, let us first see what these are.
What is a TDS Controller?
Before getting into what a TDS controller is, here is what a TDS means. TDS refers to Total Dissolved Solids.
Almost every water purifying system comes equipped with a TDS controller. Basically, a TDS controller is a device, used in a water purifying system.
This machine mixes RO purified water with the untreated water so as to achieve the ideal TDS levels.
This TDS controller reduces the TDS of water by 90 per cent. Besides, this is ideal and safe for human consumption.
The Ideal TDS for Drinking Water
Now that it is clear what a TDS controller is, it is vital to know the ideal TDS for drinking water. The ideal TDS for drinking water is between 50-500, as mentioned by BIS. Note that the lower the value, the better the consumption.
Moreover, you can have a lower amount of TDS value in your water source. In such a scenario just consider buying a water purifier that is instrumental in improving the taste, smell and quality.
However, investing in a multi-stage purification system would be a waste of money.
Working of the TDS Controller
Here is how the TDS controller works.
- Through the pre-filter, sediment filter and carbon filter, the pressurized water is pumped.
- The T-extension divides the water into two streams.
- The first stream of water passes through the RO membrane and achieves low TDS levels.
- Then the water finally reaches the UV chamber.
- On the other hand, the second stream of the chamber directly reaches the TDS controller. Later it reaches the UV chamber.
- After this, both the streams are treated under the UV lamp. It eliminates all kinds of bacteria and viruses.
- For alkalization, it is passed on to the UF filter.
- Finally, this treated water is stored in the purifier tank.
Thus, this maintains the TDS balance in the water.
What is Mineralizer compared to TDS Controller?
The mineralizer is the latest feature. Almost all the brands in India of water purifiers offer this feature. Basically, it acts on the concepts of electrolysis and ionization.
The variable voltage of DC passes through the Ionization chamber. Here the Copper and Silver results in the release of positively charged ions in the water. As a result, there is electrolysis in the water.
As Copper and Silver have antibacterial properties, this kills the germs. Also, it prevents algae from spreading.
The Working of the Mineralizer
Now that you have an idea about mineralizer, therefore, have a look at how it works.
- As the water enters the ionization chamber, the positively charged ions are released. This purifies the water.
- Silver is a natural toxin for bacteria. On the other hand, Copper removes all sorts of algae.
- Now, the mineralizer’s positive terminal produces acidic water and the negative terminal results in alkaline water.
Note that there are no side effects of this process. Both Siver and Copper have anti-toxin properties. Besides, the smell and taste get enhanced at the same time.
Comparison Between a TDS Controller and a Mineralizer (TDS Controller Vs Mineralizer)
A TDS controller ensures TDS quality of water at optimum levels. On the other hand, a mineralizer ensures the release of essential minerals, lost during the RO purification process.
Here is a comparison table between the two.
| TDS Controller | Mineralizer |
| It ensures TDS water levels at an optimum level. | It retains the lost minerals and nutrients lost at the time of RO purification. |
| The entire water does not pass through the RO membrane. | The entire water passes through the RO filter. |
| It is affordable. | It is a little expensive. |
| Not ideal for water supply with heavy metals (For example, lead, arsenic, nitrate, cadmium). | The toxic metals are removed from the water. |
| The TDS level needs to be regulated. | Absence of any other alternative to regulate the TDS level. |
| It controls the TDS level of the resultant water. | Here, there is no control over the resultant water. |
| It comes with an environment-friendly option. | On the other hand, it is not much environment-friendly. |
Final Words
Thus, to conclude, both are equally important. Both have their importance in the water purifying process.
Therefore, it is better to purchase a RO water purifier with both a TDS controller and a mineralizer.
However, you can have your opinion based on your preferences and requirements.
