Abstract
A dispenser system for treating water containing systems in place with a dry chemical substance. The dispenser has a water soluble pouch housing a dry form of a chemical material to be used in treating the system. The pouch is positioned in a make down unit so that the chemical is dissolved to form a liquid concentrate which is then introduced into a water containing system. A controller is attached to the make down unit to regulate the flow of water into the apparatus and the flow of liquid concentrate out of the apparatus and into the water containing system.
