The device is designed to improve oxygen supply in fish ponds to boost survivability and yield of the stock.
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).

Design Specifications
The device consists of a solar heat collector and a heat transfer pipe (0.5-1m) and a base flare (length 0.8-1.2m) that heats the oxygen depleted water causing it to rise and mix the pond (1500 L/hr), spreading the oxygen-rich water from the top throughout the entire pond.
Technical Support
The device is easy to manufacture and maintain from locally available materials.
Replacement Components
The system requires basic maintenance of cleaning and paint application.
