Electro-Clean 밸러스트수 처리장치의 육상시험

Abstract

This paper considers the matter of safety, environmental acceptability, practicability, and biological effectiveness for the electrochemical disinfection system, Electro-CleanTM system. This electrochemical disinfection system uses various active substances produced from electrolysis of seawater. These active substances attack simultaneously an organism or organisms for disinfection so that synergy effect can be expected. Active substances are not added to the system but produced during electrolysis of seawater. Some of active substances with a lifetime in nanoseconds like as Hydroxyl Radical are not remain until to ballast tank in a ship. The other active substances remain in the ballast tank water and the discharge water but concentration of the active substances are not so high. So treated ballast water can be discharged into the environment without any conditioning. There are no waste streams that have to be disposed of and require special concern during the system operation. Biological efficacy tests are conducted for this electrochemical disinfection system. The biological efficacy of the Electro-CleanTM system was tested using marine organisms which consisted of three groups such as 10-50㎛, ≥50㎛ and bacteria Techcross Inc., developer of Electro-CleanTM system, has started its full-scale land-based test using its own barge and shipboard test with STX Pan Ocean’s containership ever since Electro-CleanTM system was granted the basic approval from IMO in March, 2006. Techcross Inc. like to present its own designed barge for land-based test to maximize the efficiency of the test cost and time especially regarding cultivation and concentration of testing bacterias and microorganisms.
