Abstract
Displayed result that handle particle contaminant and hydrospace organism included a number of ballast that is happened in ship using automatic back washing filter. Reason that removes first contaminant that is included in number of ballast is that heighten processing effectof after processing processof the filter. Another advantage is to drop off the solids with controlling revolution of drum screen in pretreatment filtration process. The fact that it is easy to attach and detach a several type of screen for getting the expected water quality is another advantage. Filter rotation speed of filtration filter could be expose by 35mmHg more than 60 rpm and filter consecutively filtration pressure is 40.5mmHg in 20 rpm and 40 rpm are 36.6mmHg. Filtration system removal aquatic organism over $70{\mu}min$ ballast water. This study shows that the filtration treatment system has a potential for the treatment of ballast water.
