BASIC OPERATION
The AP Unit is designed to circulate water by bringing
water from below and sending it out across the top in a
thin layer causing a mixing effect.
The air diffuser creates thousands of tiny bubbles which
produces a "Low Pressure Zone" that creates an uplift
suction flow through the intake draft tube, and a slight
mound at the water surface, producing gentle flow
radially outward from the AP Unit.
The water layers flow outward radially, in diverging
“stream lines” from the unit. As it does, vertical flow is
induced in between the water being drawn below and
the water above. At the level of the flow intake, water is
drawn from all corners of the pond. As this lower layer of
fluid makes its way inward with converging streamlines
to the AP Unit, the water is forced upward, toward the
surface, providing gentle mixing, de-stratification, and
surface renewal.
The AP Unit requires a minimal amount of supplied air.
The air is supplied to the AP Unit with the optional air
feed hose that connects to air manifold.
It is acceptable to use the AP Unit on an as needed
or required basis. This will allow for reduced power
consumption and will benefit in energy savings. This will
require the AP Unit to run on a timer or local SCADA
system.
Refer to air supply manufacturer for recommended
duty cycle and other operational recommendations and
constraints.
