Abstract
Describes a method for dissolving a solid chemical material, such as calcium hypochlorite, with a solvating liquid, e.g., water, in a chemical feeder operating under positive pressure wherein an inert gas, e.g., air, is injected into the solvating liquid, e.g., by use of an injector nozzle, and the resultant mixture of inert gas and solvating liquid is forwarded to the chemical feeder. Sufficient air is charged to the chemical feeder to limit the level of solvating liquid in the feeder and thereby limit the amount of solid chemical material contacted by the solvating liquid.
