Abstract
The instant invention is directed toward an improved calcium hypochlorite feeder for water treatment applications. Tablets of calcium hypochlorite are diluted in an erosion feeder and the high pH effluent is then directed to a precipitation basin where a precipitation enhancing combination of calcium hypochlorite solution and precipitate act to initiate precipitation within the newly formed solution such that calcium carbonate scaling at the injection point and within the associated feed lines and equipment is substantially eliminated.
