Convergence Study on Hypochlorous Acid Sterilization Water Supply Device

ABSTRACT

As the COVID-19 situation continues for a long time, interest in sterilization has increased. For this purpose, a hypochlorous acid sterilizing water supply device using a metal electrode capable of making sterile water was developed. As for the metal electrode, the anode and the cathode were made of the same material, and when foreign substances were caught on the metal surface, the opposite electrode was hung to keep the surface clean. For the electrode material, a method of plating a platinum group on a metal was used to reduce the cost while maintaining the performance. It was prepared to prevent as much as possible the risk that may occur when operating the hypochlorous acid sterilization water supply device. The sterilization water had an acidity of 8.23pH, and was found to have excellent bacterial sterilization power. Even if it is used as drinking water, there is no shortage and it meets the US FDA standards. It was difficult to get data from the hospital. It is expected that it can be a way to prevent virus infection at a time when COVID-19 is not ending. © 2022 IJETAE Publication House. All Rights Reserved.
