The Aeration technology device is designed to run on solar power and is equipped with a heat collector unit and a pipe that transfers heat to the oxygen depleted bottom, inducing convective water circulation. The heated water sides and mixes the pond, spreading oxygen-rich water from the top through the entire depth of the pond. It is integrated with a smart device allowing farmers to monitor oxygen condition in order to perform the needed intervention.
The product is designed by students at the Water and Energy Research Laboratory (WERL).
