Abstract
An improved chemical feeder employing periodic partial immersion in a forced circulation system is provided having a soluble chemical hopper, and a dissolving chamber into which the soluble chemical chamber extends an adjustable distance and a discharge chamber in fluid flow communication with the dissolving chamber to selectively receive chemically treated water from the dissolving chamber and discharge it into a flow loop connected to the forced circulation system. A visual indicator ring is preferably present to show the height of the hopper. The adjustable hopper allows an expanded range of chemical feed rates for the feeder.
