ABSTRACT:
Inhibition of sulfate scale precipitation in a water system is accomplished by adding to said water system an effective threshold inhibition amount of a polyacrylic acid, phytic acid, and a phosphonocarboxylic acid containing at least one phosphono group, at least two carboxylic groups, and a hydrocarbon chain of at least two carbon atoms. The active materials are used in the ratio of 0.1 to 30 parts polyacrylic acid and 0.1 to 30 parts phosphonocarboxylic acid per one weight part of phytic acid.
