Title (EN) METHOD OF CLEANING CIRCULATORY WATER TANK SYSTEM AND DETERGENT COMPOSITIONS FOR CIRCULATORY WATER TANK SYSTEM
(FR) PROCEDE DE NETTOYAGE DE SYSTEME DE RESERVOIR D'EAU EN CIRCULATION ET COMPOSITIONS DETERGENTES PREVUES POUR CE SYSTEME
Abstract: front page image
(EN)A method of cleaning a circulatory water tank system whereby biofilms with the inhabitation of legionella, etc. can be effectively removed while scarcely damaging human bodies or the system. This method involves, in the circulatory water tank system, the step of circulating at least once water containing a quaternary ammonium salt and 2-phenoxyethanol at a total concentration of 150 to 5000 ppm and the step of discharging the water having been circulated.
(FR)L'invention concerne un procédé de nettoyage d'un système de réservoir d'eau en circulation dans lequel on peut éliminer de façon efficace les films biologiques composés de $m(f)i$m(g)legionella$m(f)/i$m(g), par exemple, en ne portant pratiquement pas atteinte au corps humain ou au système. Ce procédé consiste à faire circuler au moins une fois l'eau chargée de sel d'ammonium quaternaire et de 2-phénoxyéthanol selon une concentration totale se situant entre 150 et 5000 ppm, puis à décharger l'eau circulée.
