PROBLEM TO BE SOLVED: To provide a water treatment agent composition in which an inorganic-type slime control agent of hypobromite, and at least one of metal corrosion preventing agent and scale dispersing agent are formed into a one-pack type agent, that suppresses the conspicuous reduction in slime control performance (the conspicuous reduction in oxidizing power) of the inorganic-type slime control agent.SOLUTION: Provided is a water treatment agent composition in which a bromine-type oxidizing agent or a reaction product between bromine compound and chlorine-type oxidizing agent, a sulfamic acid compound, and a polymer comprising a monomer unit represented by the following formula are blended under a pH of 13 or more.COPYRIGHT: (C)2015,JPO&INPIT【課題】無機系スライムコントロール剤のスライムコントロール性能の著しい低下(酸化力の著しい低下)を抑制し、無機系スライムコントロール剤である次亜臭素酸塩と、金属防食剤およびスケール分散剤のうち少なくとも1つとを一剤化した水処理剤組成物を提供する。【解決手段】臭素系酸化剤、または臭素化合物と塩素系酸化剤との反応物と、スルファミン酸化合物と、下式の単量体単位を含む重合体と、がpH13以上で配合されている水処理剤組成物である。【選択図】なし
