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.

Abstract: A system for mixing dry powder and water having a non-pressurized make-up reservoir (10). The make-up water is transferred by a booster pump (14) through a transfer pipe (20) at a predetermined flow rate and pressure for operation of a dry powder eductor (26) fed through powder hopper (28). The educted powder is instantly wetted through an area causing a high shear environment (25). A solution mix tank (32) is placed within the reservoir tank (10) having a turbine mixer (40) for maintaining the polymer solution in a uniform state. The mixed solution is maintained at a predetermined level and is available for transfer through discharge port (50) in batch, upon demand.
