ABSTRACT:
A device for adding a solid additive to a liquid has a liquid inlet, a liquid outlet and a receiving container for the solid additive in the form of a tablet or bar. The tablet or bar is hollow, being shaped like a cylindrical ring. The liquid is moved axially past the inner surface and outer surface of the cylindrical ring, and during wearing away of additive material, there is a reduction in the size of the outer surface and a corresponding increase in the size of the inner surface. Therefore, the overall surface area remains constant, which leads to constant admixing. Preferably, an inner tube spaced from the inner surfaces of the additive discharges liquid for flow across the inner and outer surfaces in the same direction.
