Abstract
A novel briquet is comprised of compressed hydrated calcium hypochlorite particles having a calcium hypochlorite content in the range from about 55 to about 75 percent by weight, a water content in the range from about 4 to about 10 percent by weight and a compression strength of from about 2 to about 95 kilograms. The briquets may be used in sanitizing water supplies as they dissolve slowly to release available chlorine at a controlled rate.
