APPARATUS AND METHOD FOR CONTROLLING CONCENTRATION GRADIENTS

摘要

The present invention discloses and claims a fill system and method for reducing the chemical concentration gradient in absorbent materials. The fil l system includes a source of liquid connected to a nozzle for dispensing the liquid into a container. The nozzle includes a dispersal face that defines primary apertures approximately equidistant from the outer perimeter and center poin t on the dispersal face. The nozzle may also include secondary apertures proximat e to the outer perimeter and one or more tertiary apertures proximate to the cent er point. The dispersal of fluid through the secondary or tertiary apertures ma y be less approximately one-half of the dispersal of fluid through the primary apertures.
