BALLAST WATER DE-TOXIFICATION TREATMENT SYSTEM FOR SHIPS

摘要

Methods and compositions for reducing the number of viable organisms present in ship ballast water comprising treating the ballast water so as to reduce the concentration of dissolved oxygen and/or carbon dioxide to a level(s) at which a substantial portion of the organisms present cease to remain viable. Preferably, the method involves treating the ballast water with iron powder so as to reduce the level of dissolved oxygen to 5mgl-1.
