The results of the water stabilization treatment studies to feed the cooling water circulation systems by ion exchange method are reported. The processes of the water softener on strongly and weakly acidic cation resins in the presence of copper ions are studied. The relation of the water purification efficiency from copper and its softening depending on the form of the ion-exchanger and water consumption was determined. It is shown that the use of weakly acidic cation resin in the acid form provides nearly complete decarbonization of water by partial acidification. The use of ion exchangers in salt form allowsto neutralize the waterwith effective mitigation and clean-up of the copper ions. The processes of cation resin regeneration by acidic and saline solutions were analyzed. It is shown that the make-up cooling systems by softened water will introduce stagnant circulation cooling system that will provide reliable protection of waters from pollution by power plan wastewater copper ions.

Keywords: cation resin, heavy metals, ion exchange,ion-exchanger regeneration, water circulating systems.
