摘要

An apparatus for preparing a chemical solution includes a lower housing and an upper housing. The lower housing has a base, an upper plate having a central opening, and a side wall. A grid mounted on the upper plate covers the opening. A wall within the lower housing divides the interior of the lower housing into a central inner chamber and an annular outer chamber; this wall extends into an upper portion of the lower housing. One portion of the wall has a reduced height to permit fluid flow from the inner chamber to the outer chamber. A nozzle is mounted in the inner chamber for discharging fluid into the inner chamber, and causes local elevation of a portion of the fluid surface above the grid. The nozzle may be an eductor creating a venturi effect to draw fluid into the eductor.
