How does the TDS Controller work?

Lets learn how TDS controller works.

The inline water going into the RO Purifier flows thru Pre filter, Sediment Filter, Carbon Filter, and is then divided into 2 different sections from here.

1:  First half of the water is directed thru RO membrane where it becomes soft water with lower TDS level, and then it reaches the UV Chamber.

2: The other half is directly added into the UV Chamber with help of this valve called the TDS Controller.

3:  Then both of these water flows are mixed up and treated by the UV lamp to kill all bacteria, virus, pathogens and passed on to the UF filter, then Alkaline chamber ( Your water purifier have an alkaline unit ?) and finally into the tank where its stored for later use.

The TDS controller works same in all RO systems. But TDS controller works in Kent RO is a bit different but the results are almost same.
