Abstract
A solid chemical feed system, preferably including two feed bowls, comprises a quantity of solid chemicals that dissolve upon immersion in water to form a liquid solution. A sump is provided to receive liquid solution from the feed bowls, the liquid solution with additive chemicals being used as a treatment for cooling towers, boilers, or other industrial processes to inhibit corrosion and rust. The feed system comprises a valve system that is controlled by a sensor that detects the conductivity of the liquid solution to alternatingly switch the introduction of liquid solution from one feed bowl to the other feed bowl. As such, upon depletion of chemical feed in one bowl, desired treatment will continue and the empty bowl may be replaced without disruption of liquid solution supply.
