Full-lift hypolimnetic aerators — airlift columns that raise cold bottom water, aerate it at the surface and return it to depth without breaking stratification.
Hypolimnetic Oxygenation — in depth
Full-lift aerators oxygenate the hypolimnion while preserving the cold, stratified bottom layer that fisheries and water quality depend on. An airlift draws hypolimnetic water up a column, releases gas at the surface and returns the re-oxygenated, still-cold water to depth — adding oxygen without warming or mixing the lake.
What matters in practice
Rising bubbles lift bottom water up the riser.
Water aerates and degasses at the top.
Cold, oxygenated water returns below the thermocline.
No warming or destratification of the lake.
