GESAMP invites MEPC 59 to:

agree that Final Approval is given to RWO Ballast Water Management System CleanBallast submitted by Germany comprising:

• Disc Filter unit
• Advanced EctoSys electrolysis
• Neutralization (thiosulphate)

Therefore the CleanBallast system will be submitted for approval to the MEPC 59 , July 2009. It is expected that CleanBallast will receive type approval from the German Administration BSH after MEPC 59.

RWO comments additionally: The RWO CleanBallast uses extremely short lived OH-radicals when operating in fresh water. Therefore the system is capable of operating efficiently in fresh water; the system was successfully tested with river water in the port of Bremen.
