SEOUL, Nov. 2 (Korea Bizwire) – The Seoul Metropolitan Government announced on Wednesday the development of innovative technology for efficiently blending carbon dioxide and ozone, essential components for improving the quality of tap water, during the production process of Arisu, Seoul’s tap water brand.
Carbon dioxide plays a crucial role in enhancing water purification efficiency by neutralizing the water. It is introduced into the source water of Arisu from the Han River.
Ozone, on the other hand, is a substance utilized in advanced water purification treatment following the standard purification process. With its potent sterilization effect, ozone is employed to eliminate taste and odor components from the water.
The city government noted that this new technology will significantly contribute to the improvement of tap water quality by efficiently eliminating taste and odor-inducing substances.
To achieve this, the city government upgraded the technology for dissolving carbon dioxide into the water, transitioning from the traditional single-injection method to an evenly distributed spraying method employing six nozzles. The injection point was also relocated from the front to the rear of the receiving well.
According to the Seoul Water Institute, the installation of the carbon dioxide mixing device at the rear of the receiving well resulted in an increase of over 20 percent in dissolution efficiency.
For the efficient blending of ozone, a three-layered mixing grid was installed in front of the ozone contact chamber. This setup significantly alters the water flow’s intensity as it passes through the mixing grids, ensuring the uniform mixing of water and ozone. This method led to an increase in the mixing rate from 65 percent to 71 percent, as reported by researchers.
