Koreans confident of success

摘要

Only two Asian ballast water treatment systems have been granted IMO basic approval status: the Japanese Special Pipe system and Electro-Cleen, developed by South Korea's Techcross. The Electro-Cleen system disinfects ballast water using sodium hypochlorite and hydroxyl radicals produced by electrolysis of the ballast water itself, meaning that no chemicals have to be stored onboard. Electrolysis takes place in a module installed in the ballast pipeline and the system needs no additional pre-filter to satisfy IMO's Regulation D-2 regarding biological performance standard.
