Abstract

Chemical and mineralogical compositions of mineral deposits and acidic precipitations have been studied, and synergistically effective compositions of inhibitors of salt deposits have been selected based on -PO3H2 and COOH containing organic compounds. The article proposes a formulation of a mineral salts deposit inhibitor corresponding to regulatory indicators (not less than 90%) for the protection of municipal boiler houses and industrial equipment, comparative results of the industrial preparation Komperex-710. The obtained compositions were found to be effective inhibitors in concentrations of 8-12 mg/l in waters with calcium and magnesium chlorides Chimbaia, Turtkulia and Biruni with hardness of 7.9-9.6 mg.eq/l and in concentrations of 10-14 mg/l in waters with calcium and magnesium carbonates Nukus and Shukmanay
