You have seen the functions and the working of the TDS controller. There is a new concept in water purifying technology that uses mineralizers.
Let us see what a mineralizer is and how does it work. This will explain the difference between the TDS controller and the mineralizer.
There is a release of positively charged ions of copper and silver. Copper and silver ions have anti-toxic properties. Silver is a natural toxin for bacteria and copper to algae.
The release of these positively charged ions purifies the water completely without causing any side effects that you would usually observe when you use chlorine for purification. The resultant water has a refreshing smell and taste.
This is not possible in the case of TDS controllers. When you use TDS controllers, you mix purified source water with normal TDS along with RO purified water with a minimum concentration of TDS.
Strictly speaking, you infuse the same minerals that the RO process has eliminated. Of course, you purify the water by passing it through the UV chamber and UF membrane.
Nevertheless, you do not remove the heavy metals like arsenic, lead, or mercury. Theoretically speaking, you contaminate the water purified by the RO process. The Mineralizer differs in the sense that it infuses the lost minerals alone and this certainly does not include the heavy metal impurities like arsenic, lead, or mercury.
This is not to say that the TDS controller is ineffective or anything of that sort. Both TDS controller and the Mineralizer have their importance in the water purification process.
