Abstract
An apparatus and method for dissolving a chlorine containing treating material such as calcium hypochlorite in which water is fed to a container preferably in the form of a column containing the treating material. The water is caused to cyclically rise in the container to a predetermined height to dissolve a portion of the material and then discharge to a storage container to empty the material containing container. The height at which the water rises within the container, the cross-sectional area of the container and the length of time the liquid is in contact with the material during the cycle is set to produce a solution having a concentration of from between about 2 to about 18% available chlorine at a feed rate of at least about 2 lbs/hr available chlorine. The cyclical action is preferably achieved through the use of a siphon tube connected to the material holding container and through which the fluid in the container is discharged. The ratio of the internal cross-section area of the column to the internal cross-sectional area of the siphon tube is less than 700 and preferably in the range of 500 to 100.
