  • Patent number: 6221321
    Abstract: A chemical feeder for use in a water circulation system includes a body, a head attached to the top of the body, and a flow passage extending through the head. A portion of the water flowing through the flow passage is diverted into the body, where the water mixes with chemical tablets contained therein. A strainer is positioned inside the body and a stand pipe connects the strainer to the flow passage. Venturi forces within the flow passage draw the chemical solution from the body and into the flow passage, where the chemical solution mixes with the water flowing therethrough. It is possible to control the concentration of the chemical solution by controlling the flow of fluid from the flow passage into the body.
