Abstract

Une composition d'hypochlorite de calcium solide contient de l'hypochlorite de calcium hydraté et un sel de métal alcalin d'un acide polycarboxylique de phosphonobutane ayant une concentration en chlore disponible d'au moins 50 p. 100 en poids et une teneur en eau d'au moins 4 p. 100 en poids. On a découvert que l'utilisation des compositions nouvelles dévoilées peut réduire significativement l'entartrage des distributeurs d'hypochlorite de calcium, en particulier dans les endroits où l'alcalinité totale de l'eau est élevée. On réussit donc à prévenir ou à inhiber l'entartrage sans nuire aux autres propriétés de l'eau de la piscine comme le pH.
