The article presents research results on carbonate system components of cooling water, which has previously undergone water treatment by liming, depends on the cycle of concentration and absorption of carbon dioxide, which simulate the processes of evaporation and aeration in circulation cooling systems (CCS) of power plants. pH was an indicator chosen to identify components of carbonate system components of the given research. Were carried out experimental studies, control data were analyzed regarding pH and carbonate system component changes of technological and circulating water of the CCS during water treatment by liming according to the stabilization treatment method, namely the use of mineral – sulphuric acid. It was shown that during cooling water aeration in the cooling tower the absorption of carbon dioxide from the air occurs, which causes a shift in the equilibrium of the carbonate system with a decrease or increase of carbonate alkalinity, bicarbonate content, carbonate ions and pH with or without applying stabilization treatment by sulphuric acid.
