PURPOSE:To prevent corrosion of metals in aq. system and to prevent simultaneously generation of scale, dirts, and troubles due to microorganisms without causing contamination of water, by using the title water treating agent comprising a combination of glutaric dialdehyde and a specified polymer. CONSTITUTION:(a) At least one kind of polymer (including homopolymer and copolymer) comprising as essential monomer at least one kind of monomer selected from a group of acrylic acid, acrylic acid derivs., maleic acid, and maleic acid derivs., and (b) glutaric dialdehyde and/or its deriv., are incorporated as effective components. The mol.wt. of the above described polymer is regulated to be in a range of 500-1,000 weight average mol.wt., and the proportion by weight of the polymer to glutaric dialdehyde is regulated to be in a range from 10:1 to 1:10. By using the water treating agent, the corrosion of metals in the aq. system and generation of scale, dirts, and troubles due to microorganisms, are all prevented simultaneously by the use of a one-component liquid agent and a single injection device. |
