Abstract: Powdered polyelectrolytes are wetted and mixed with water in a cone-shaped member to form solutions which are useful, for example, in promoting floc formation for removal of suspended particulate matter. Improperly wetted and/or mixed powders tend to form lumps to periodically clog the throat of an eductor conventionally employed in the formation of such solutions. The present invention employs an orificed disc to form multiple jets of high velocity water to impact any lumps exiting from the lower portion of the cone-shaped member for break-up of said lumps to thereby provide a lump-free solution which does not clog the throat of an eductor disposed downstream of the orificed disc, the eductor educing the lump-free solution into an aging and/or storage tank.
