The effect of corrosion inhibitors and microbiocides presented in circulating water supply systems on the corrosion rate of structural materials has been studied. It is shown that using the mixture of zinc phosphonates aqueous solutions, special polymeric dispersants and microbicides based on bromine and quaternary ammonium salts provides dissolution of calcium carbonate deposits and the corrosion rate of steel materials at the lowest level. Rational modes of circulating water chemical treatment are proposed, which increase operational reliability. The electrical conductivity of KU-2 resin, which will be used for intermembrane filling during electrodialysis of makeup water in a circulating water supply system has been determined to prevent the salts concentration.
