Abstract
Способ предотвращения солеотложений, коррозии и биообрастаний в системах водоснабжения путем введения в обрабатываемую воду гексаметилендиаминтетраметиленфосфоновой кислоты и ее металлсодержащего комплексоната при мольном соотношении 3:1-2:1, отличающийся тем, что металлсодержащие комплексонаты в качестве металла содержат цинк и медь при их мольном соотношении 0,75:0,25÷0,5:0,5 соответственно. A method for preventing scaling, corrosion and biofouling in water supply systems by introducing hexamethylene diamine tetramethylene phosphonic acid and its metal-containing complexonate into the treated water at a molar ratio of 3: 1-2: 1, characterized in that the metal-containing complexonates contain zinc and copper as their metal at a molar ratio of 0 , 75: 0.25 ÷ 0.5: 0.5, respectively.
