AER-O-MIX
The apparatus known as the Aer-O-Mix was first used in January 1929. The
water flows into the tank surrounding the Aer-o-mix head, enters the head
through the apertures in the perimeter, then passes downward through the
annular throat and past the lower ends of the multiple tubes in the head,
drawing bubbles of of air down through these tubes, by aspiration. The
mixture
of water and bubbles passes downward through the retention pipe,
through the
U turn and up again and through a discharfe plate where the
air is released. A
modification of this design is used where there is
not sufficient head for
the water to flow through the aerator by gravity.
In that case a vertical
motor is mounted above the head, its shaft
extending downward thrugh the center
of the head, being connected to an
impeller in the top of the retention
tube. The action of the impeller
forces the water down through the tube.
