Electrochlorination systems are widely used in ballast water treatment because they are more cost-effective than other disinfection techniques. Furthermore, the on-board generation of hypochlorous acid from electrochlorination systems has advantages in terms of footprint size and safety as there is no need to store highly concentrated hypochlorite solutions. Recently, several studies focused on the injection of carbon dioxide into an electrochlorination system to enhance disinfection efficacy. However, the treatment efficacy of injecting exhaust gas into an electrochlorination system remains understudied. In this study, the disinfection efficacy of Artemia sp. was investigated based on the holding time when carbon dioxide was injected into the electrochlorination system. Disinfection efficacy significantly improved as the pH decreased to 5.5. Additionally, the pH inside the ballast water tank adjusted based on ballast water flow capacity when the carbon dioxide from combustion engine was fully dissolved. Our results showed that the pH suitable for eliminating microorganisms was achieved using only the auxiliary engine without any acid additives. This study provides a promising conceptual design for ballast water treatment.
