A study of Ballast water Treatment using a Disk filter
디스크 여과장치를 이용한 선박 밸러스트수 전처리 연구
Abstract
Displayed result that handle particle contaminant and hydrospace organism included in number of ballast that is happened in ship using automatic back washing filter. Reason that remove first contaminant that is included in number of ballast is that heighten processing effect of after processing process. of the filter. Another advantage is to drop oft 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 at 1.0rpm is filter resistance 3.0bar and 3.0rpm is filter resistance 2.8bar. Filter out impurities from ballast water over 6.0rpm is filter resistance 2.6bar and 10rpm is filter resistance 2.5bar. Filtration system removal aquatic organism over
