<p>The present invention relates to a chemical feeder that includes a support plate that is positioned within the housing chamber of the chemical feeder, in which one or more extensions extend upward from an upper surface of the base plate of the support plate. The extensions can, with some embodiments, be in the form of peg extensions, arcuate extensions that can together define an impeller pattern, or a spiral extension. A distributor head having a plurality of distributor head apertures and at least one dome hole extends up through a support plate aperture in the base plate of the support plate, and distributes liquid horizontally and vertically relative to the base plate. The horizontally and vertically distributed liquid contacts a solid chemical material that is supported above the support plate, so as to form a treated liquid that includes dissolved chemical material.</p> |
