Abstract
A continuous method is provided for dissolving a solid oxidizer into an aqueous solution which yields a stream of the aqueous solution having a constant or near constant concentration of solid oxidizer. The method of the present invention includes (a) disposing a bed of solid oxidizer into a container; (b) introducing an aqueous solution below the top surface of the bed; and (c) removing any solution above the top surface of the bed while maintaining a constant or near constant level of aqueous solution above the bed. Preferably, step (c) is performed at about atmospheric pressure. This method can be achieved with a feeder that includes a tank for containing a bed of solid oxidizer and a disperser for introducing the aqueous solution into the tank. A sensor/control unit is provided for sensing a combined bed and aqueous solution volume within the tank and maintaining the combined volume within a predetermined range.
