Swimming pool or drinking water is chlorinated by the use of an intermittent spray-type chlorinator assembly. The chlorinator assembly includes a chamber for holding a quantity of solid dry chlorinating chemical, typically in the form of briquettes or pellets.The water spray impacts, abrades, and dissolves the briquettes to a degree, and at a rate which is controlled by the velocity of the spray; the diameter of the support grid; the percentage of open space in, and the thickness of the support grid; and the cyclic timing of the spray. The chemical-water mixture falls into a chamber below the spray and is evacuated therefrom through discharge/check valve assembly to a return line that leads back to the source of the water being chlorinated. The spray duration times and the intervals therebetween can be selectively changed by an attendant. By using a water spray technique for periodically abrading and dissolving the chemical briquettes, a highly soluble solid chemical such as calcium hypochlorite can be used as the water treatment chemical. Additionally, intermittent spraying limits the buildup of scale in the system.
