FIELD: construction.
SUBSTANCE: composition comprises, by wt %: sodium tripolyphosphate and/or sodium dihydrogen phosphate (in sodium oxide equivalent) 53.00-73.00; dihydrogen calcium (in calcium oxide equivalent) 26.65-44.00; zinc nitrate (in zinc oxide equivalent) 0.35-3.00.
EFFECT: comprehensive protection against corrosion, scaling, formation of biofilm made of highly toxic microorganisms, as well as improvement of the quality of treated water by saturating it with physiologic zinc cations, phosphate anions and prevention of formation of toxic phenols, highly toxic chlorophenol compounds in water during chlorination of water while maintaining the mineral composition of the source water.
