methods for dissolving solid chemical feed unit, for enclosing carrier in dissolution vessel, processes for producing chemical solution and for feeding process dissolved solid chemical and equipment for dissolving a chemical unit for dissolving The solid chemical feeder 18 has an upper feeder unit chamber 26, with an inwardly tapered sealing surface 20 at its lower end and against which a lower feeder unit seals, retaining the upper chamber 26 in a dry condition, preventing wetting and agglomerating solid chemical feed units behind the dissolving and sealing face of the solid chemical feed unit 18. a solid chemical feed unit carrier 16 is slotted to allow smooth feeding of a pluralid A solid chemical feeder unit 10 is provided, and a sight slit, defined on the lid, guides and visually observes the remaining solid chemical feeder units in the carrier. carrier 16 preferably but not necessarily defines the tapered sealing surface 20. distinctly shaped solid chemical feed units 10 are disclosed. dissolution can handle large loads of solid chemical feed units up to forty-five kilograms (100 pounds) or more and in a stable, small print configuration. methods are disclosed.
