Abstract

A dispensing device comprises a body having a chamber sized to accommodate a volume of solid halogen source therein. The chamber comprises an open end and a closed end. A number of apertures extend through the body and into the chamber near the closed end. A control member comprises an open end and a closed end separated by a wall. The open end of the control member is rotatably mounted over the closed end of the chamber. Openings extend through the wall and are positioned at locations that correspond to the apertures so that alignment of the openings with respective apertures form dispensement ports. The ports has a degree of closure that can be precisely controlled by rotation of the control member about the body for dispensing the halogen solution to the water. A cap is releasably attached to the open end of the chamber to form an air and water-tight seal therebetween, creating an air head within the body when placed into the water. The air head controls the amount of solid halogen source wetted to that portion adjacent the apertures. Water is circulated through the apertures to wet the solid source and generate halogen solution. Controlled solid source wetting and variable adjustment of the dispensement ports permits halogen solution to be dispensed to the water in a precisely controlled manner.
