A chemical feeder includes a housing having a housing chamber, a sieve plate within the housing chamber, and a cartridge on an upper surface of the sieve plate. The cartridge includes a tubular member with a sidewall outer surface and a plurality of partitions extending from the sidewall outer surface to define a plurality of pockets, at least one of which contains a solid chemical material. The sieve plate includes a plurality of sieve plate inlet apertures, at least a portion of which are in fluid communication with at least one of the plurality of pockets. During operation, a feed liquid passes up through at least a portion of the sieve inlet plate apertures and into at least one pocket where it contacts a solid chemical material, so as to form a treated liquid that includes dissolved chemical material, at least a portion of which is removed through an outlet.

Chemical feeder

The present invention relates to a chemical feeder that includes a housing having a housing chamber, a sieve plate residing within the housing chamber, and a funnel residing on an upper surface of the sieve plate. The funnel includes upper and lower openings, an interior funnel space, and at least one funnel sidewall aperture. The sieve plate includes a plurality of sieve plate apertures at least a portion of which are in fluid communication with the interior funnel space via the lower funnel opening. During operation, a feed liquid passes up through at least a portion of the sieve plate apertures and into the interior funnel space where it contacts a solid chemical material, so as to form a treated liquid that includes dissolved chemical material, at least a portion of which passes out through the funnel sidewall aperture(s) and exits the chemical feed through an outlet.
