| titleOfInvention | Concentration management method for water treatment chemicals in cooling water system |
| abstract | PROBLEM TO BE SOLVED: To quickly and accurately measure and monitor the concentration of an active ingredient in circulating water, and to appropriately control the concentration of a chemical for water treatment in a cooling water system. SOLUTION: Isothiazolones and polycarboxylic acids acting as effective components of a chemical for water treatment in a cooling water system having a cooling tower and a heat exchanger are quantified and monitored by a chemiluminescence method. A complex of a transition metal element such as ruthenium and a nitrogen-containing aromatic ligand and / or an ammonium nitrate salt of a rare earth element such as cerium is oxidized to increase the oxidation number of the transition metal element and / or the rare earth element, The oxidant thus obtained is brought into contact with the sample water of circulating water to cause chemiluminescence, the luminescence intensity is measured, and the concentrations of isothiazolones and polycarboxylic acids are quantified. Based on the quantitative value, the required amount of water treatment chemicals such as isothiazolones functioning as fungicides and slime control agents, and polycarboxylic acids functioning as scale inhibitors, dispersants, anticorrosives, flocculants, etc. is cooled. By adding and replenishing the water system, the concentration of the chemical for water treatment in the cooling water system can be controlled. |
