Abstract

PURPOSE: To effectively suppress the production of scale which would be separated and deposited in the concentration or heat exchange of fresh water, sea water or the like, by using a polycarboxylic acid (salt) and a surface active agent together.
CONSTITUTION: The production of scale is suppressed by a scale suppressing agent, which jointly employs a polycarboxylic acid such as polyacrylic acid, polymaleic acid, polymethacrylic acid or their copolymer with a polymerization degree of about 5W500 and a surface active agent, particularly a nonionic surface active agent having an alcoholic hydroxyl group. The suppressing agent completely prevents the deposition of hard scale. The agent not only facilitates the removal of scale but also produces a greatly improved scale suppression effect.
