Abstract:
A process for feeding calcium hypochlorite pellets to a water conditioning system comprising:providing a dry chemical storage hopper for holding calcium hypochlorite pellets;flowing said calcium hypochlorite pellets downwardly through said hopper;providing a water distribution conduit disposed within said dry chemical storage hopper and constructed and arranged so as to emit water from the perimeter thereof;providing an inlet water feed conduit in fluid communication with said water distribution conduit and providing a supply of water thereto;providing an erosion chamber positioned downstream from said water distribution conduit and in fluid communication therewith, causing water emitted from said conduit to flow over said calcium hypochlorite pellets, forming a calcium hypochlorite solution having a pH in the range of about 8.3-10.5;providing a chlorine feed control valve in fluid communication with said conduit and constructed and arranged such that calcium hypochlorite solution will be formed when demanded by the system;transporting said calcium hypochlorite solution through a solution guide pipe and into a precipitation basin;allowing a precipitate to form and retaining said calcium hypochlorite solution and said precipitate in said precipitation basin; andinjecting the calcium hypochlorite solution and precipitate into said water conditioning system;whereby the calcium hypochlorite solution, in combination with the precipitate formed and retained in said precipitation basin, provide enhanced precipitation of newly formed calcium hypochlorite solution therein, thus retarding the formation of calcium carbonate scale deposits within said system.
