Abstract

A chemical feeder that produces a solution of a chemical treating agent, e.g., calcium hypochlorite, is described. The chemical feeder comprises a housing (22) having a base (36), side wall (20) extending upwardly from the base, and a closed upper end (28), all of which define a cavity (2). An elongated substantially vertical hollow container (10) is centrally located within the cavity. The bottom of the side wall (12) of the container is adjacent to the base, and contains a plurality of perforations 14 in the lower portion of the side wall, which is spaced from the inside side wall of the housing. At least one hollow canister (40) having a plurality of perforations (47, 49) in its base and the lower portion of its side wall is interposed, e.g., slidably received, within the container. Conduits for delivering liquid (32) in which the chemical treating agent is soluble to a chamber (5) below the perforations in the canister and for removing a liquid stream (30) containing the chemical treating agent from the feeder are also provided.
