GEA Westfalia aims to clean up

摘要

Nowadays, more than 10 billion tonnes of ballast water are estimated to be travelling at any time with ships on the world's oceans. Including the stowaway microorganisms and life forms which, in this way, easily overcome the normally insurmountable obstacles posed by the oceans.The IMO has, for this purpose, set up clear rules stating how ballast water has to be treated in order to prevent this risk to the aquatic ecosystems world-wide. Probably by no later than 2017 (assuming that the convention is ratified), a regulation will come into force for all vessels specifying that ballast water may be discharged in ports only if specific threshold values according to the D2 standard are complied with.
