Installing a floating U-tube air lift aerator costs less and
uses less energy than placing an air diffuser on the bottom
of your pond or floating a fountain spray on top of the pond.
Air Lift Reactors (ALRs) are well documented. Our 4" solar
powered draft tubes can turn 5 lpm of fine bubble aeration
into 50 lpm of top to bottom pond destratification mixing.
All while providing a zero carbon footprint and twice the
oxygen transfer efficiency, at a fraction of the cost of
maintenance of high pressure grid powered bubblers or
high speed mechanical aerators.
Powered by our solar aerators you will never pay a power
bill for aeration again!!!
Bottom mounted air diffusers are undesireable
from every standpoint because they make:
HIGH ENERGY USE: Every foot of diffuser depth or
fountain spray height increases the cost of the aerator
operation. Draft tubes can use less than 10% of the energy
while supplying the same oxygen transfer and mixing as
fountains or bottom mounted diffusers.
MAINTENANCE A NIGHTMARE: Every foot of depth
doubles the pump mechanical stress and maintenance
costs. (ask them about the pump warranty!)
MUCK & BOTTOM SLUDGE REDUCTION: Fixed
position bottom mounted diffusers have limited use for pond
solids reduction. Bottom mounted solids mixing "zone of
influence" is tiny compared to PEC floating draft tube
technology. In comparison our PEC DT solids mixing
"zone of influence" can be than 1000 times greater than
any fixed position bottom diffuser. The PEC DT forced
discharge vertical flow drives the unit throughout the
anchored zone. When desired, the PEC DT inlet can be
extended into the bottom solids or sludge zone. In this
manner, solids are constantly recirculated and distributed
throughout the anchored zone of influence. This enhances
the aerobic solids reduction process similar to the
"activated sludge" process and reduces the sludge volume
in your pond or lagoon more than 10 times faster than the
anaerobic solids digestion process alone.

Air is pumped deep inside a downward
hanging tube, the air mixes with the water
making it lighter and lifting it to the top of
the tube. The upward flowing air then
forces it vertically out annular openings
near the top of the tube.
