The wastewater
inflow enters the Vortex Channel having a slope and a decreasing radius. The flow is
therefore accelerated.
2.
The accelerated flow
is directed into a vertical shaft of a relatively smaller diameter. The entrance to the
Vortex Shaft is through a special Top Cut, profiled to maintain stable, smooth
vortex flow for changing flow volumes.
3.
The wastewater
spirals down along the wall of the shaft. In the center of the spiral is a stable air
core. Air from the surrounding atmosphere is dragged down by the falling wastewater,
resulting in a slightly negative air pressure above the Vortex Form. This is the mechanism
by which odor emissions are eliminated.
4.
The spiraling flow
continues downward inside the shaft into an Energy-Dissipating Pool. At this point is the greatest
energy dissipation and intensive air-flow mixing. The
mixing provides a means for flow aeration and hydrogen sulfide
oxidation.
5.
As the
air-flow
mix exits the submerged part of the shaft, the remaining flow energy is
dissipated through internal friction.
6.
Tranquil flow exits
the drop structure through its effluent line. The processes of sulfide oxidation continue
down the line.
7.
Throughout the
process, there is no abrasive wear of the drop structure because there is
no direct contact between energetic flow and the structure walls.
8.
There is
practically no
corrosion of the drop structure because the corrosive hydrogen sulfides
are not emitted and are effectively oxidized.
