SDGs

The solar water circulation system installed on the site of Kyungpook National University can smoothly continue water at the bottom of the reservoir in a vertical and horizontal direction using an impeller to reduce water temperature as low-temperature deepwater circulates with high-temperature water at the top and prevents stratification of reservoir water to prevent algae from growing. It also attaches underwater amplifiers to increase the concentration and limit the depth of dissolved oxygen in deepwater, thereby improving water quality and contributing to supplying clean and safe water.
