A water treatment method for inhibiting the formation of scale in a cooling water system is provided to offer a superior scale suppression effect though a small quantity of jetting concentration. A water treatment compound consists of organic phosphate compound of 0.1-40 weight %, acrylate co-polymer of 0.1-30 weight % and water of 30-99.8 weight %. The organic phosphate compound is the mixture including two selected from hydroxy ethylidine diphosphonic acid, hydroxy phosphono carboxyl acid, amino trimethylene phosphonic acid, phosphono butane tri carboxyl acid and ethylene diamine tetra methylidine phosphonic acid. Preferably, in the water treatment compound, the organic phosphate compound of 1.0-35 weight % is used. |
