<p>A solid calcium hypochlorite composition that inhibits the formation of scale deposits, e.g., calcium and magnesium carbonate scale, when dissolved in water is described. The solid composition comprises a mixture of calcium hypochlorite and a scale-inhibiting amount of a solid alkali metal phosphate, e.g., sodium tripolyphosphate, which is commingled with the calcium hypochlorite. Also described are solid shaped articles, e.g., tablets, comprising the solid calcium hypochlorite composition of the present invention. The solid compositions of the present invention, in particular solid shaped articles, e.g., in the form of tablets, can be used in existing chlorination units without any need to structurally modify or augment the units.</p> |
