Answer 1

Answer:

They are important.

Explanation:

TDS controller is a screw-based device that controls the level of salts in the purified output water. It works as a bypass valve which takes a percentage (adjustable) of source water bypassing RO membrane to the output water, which is then filtered through a UF or carbon filter, and/or UV chamber.
