Abstract

Fremgangsmåte for å behandle ballastvann hvor ballastvannet ledes inn i en ballasttank (12) via et fallrør (1) og hvor et undertrykk som dannes ved fallrørets (1) øvre parti (10) bevirker at gassbobler dannes i ballastvannet, og hvor ozon tilsettes ballastvannet før eller idet ballastvannet strømmer inn i fallrøret (1).A method of treating ballast water where the ballast water is fed into a ballast tank (12) via a drop pipe (1) and where a negative pressure formed at the upper portion (10) of the drop pipe (1) causes gas bubbles to form in the ballast water and where ozone is added to the ballast water before or as the ballast water flows into the drop pipe (1).
