I want to know about the chelation value, and how thay react with impurity of water. What is the actual chelation value to cure our reverse osmosis system and how?

Chelate is a complex one, in the chelate structure, must have one or more multidentate ligands provide electron and the center of the coordination bond formation.

Chelate complex than is usually to stabilize their structures often have five or six-membered ring structure is more
enhanced stability. Because of this, stability constants of
chelates are very high, many of the chelation reactions are quantitative, and can be used to titration.
