There are a number of techniques to eliminate organisms in ballast water: physical, mechanical and chemical. Electrochemical generation of disinfectants, especially oxidants as HOC1, is an emerging technique. In situ electrochemical generation of chlorine onboard would have many advantages like eliminating storage and handling of chlorine gas or HOC1 solutions. Sea water contains a wide range of salts at various concentrations and combinations having a direct effect on the capability of an Electro Chemical system to function successfully. The aim of this study is to optimize onboard chlorine generation to disinfect ballast water organisms. A laboratory system "test bed" is used to test assumptions and proposals for cell design. Chlorine generation by electrolysis of saline water and seawater by special types of electrochemical cells is investigated. © 2010 The Royal Institution of Naval Architects.
