Abstract: Apparatus and method for dissolving chemical tablets for creating a variable rate of chemical dissolution in a stream of constant flow rate of untreated liquid, especially water. The apparatus includes a housing in which a container is placed. The container includes a sieve plate or perforated grid which separates the container into an upper chamber in which chemical tablets are stored and a lower mixing chamber. A collection reservoir is defined in an annular outside the container wall and inside of the housing. Several arrangements are illustrated by which a vortex of liquid is generated of controllable variable intensity in the lower or mixing chamber thereby creating uneven liquid pressure beneath the perforated grid as a function of radial distance. As a result, fluid passes aggressively through outer radial perforations or holes in the grid and which impinge on the chemical tablets stacked on the grid.
