Title
(EN) COMPOSITION, SYSTEM, AND METHOD FOR TREATING WATER SYSTEMS
(FR) COMPOSITION, SYSTÈME, ET PROCÉDÉ DE TRAITEMENT DE CIRCUITS D'EAU
Abstract
(EN)
A composition for treating a water system to remove scale, microorganisms and brofilm, and corrosion by-products. The composition comprises chelating agents and a surfactant. Depending on the water system being treated, the composition may be a solid dissolved by water in the system being treated or may be a pre-mixed foam or aerosol. A treatment system particularly suitable for flowing water systems comprises a container for holding such a treatment composition and mixing it with a portion of water from the water system, a filter for removing solids dislodged during treatment, and a corrosion monitor. A method for using such a treatment composition comprises draining substantially all existing water in the water system, filling or rinsing the system with fresh water, contacting the treatment composition with substantially all parts of the water system, and draining the treatment composition from the system before resuming norma! operations.
(FR)
La présente invention concerne une composition pour le traitement d'un circuit d'eau afin d'éliminer le tartre, les micro-organismes et le biofilm, ainsi que les sous-produits de corrosion. La composition comprend des agents chélatants et un tensioactif. En fonction du circuit d'eau traité, la composition peut être un solide dissous par l'eau dans le circuit traité ou peut être une mousse ou un aérosol pré-mélangé. Un système de traitement particulièrement adapté à des circuits de circulation d'eau comprend un récipient pour la rétention de ladite composition de traitement et son mélange avec une partie de l'eau provenant du circuit d'eau, un filtre pour l'élimination des solides délogés durant le traitement et un dispositif de surveillance de la corrosion. Un procédé pour l'utilisation d'une telle composition de traitement comprend le drainage de sensiblement toute l'eau présente dans le circuit d'eau, le remplissage ou le rinçage du circuit avec de l'eau fraîche, la mise en contact de la composition de traitement avec sensiblement toutes les parties du circuit d'eau, et le drainage de la composition de traitement du circuit avant la reprise des opérations normales.
