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 deep water circulates 

with high-temperature water at the top and prevents stratification of reservoir water from preventing 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.
