Rotational Cleaning Filter for Ballast Water Treatment System

摘要

Our ballast water treatment system, ECOMARINE, has a unique rotational cleaning (RC) filter for pretreatment followed by treatment with ultra-violet or electrolysis chlorine. The RC filter can remove above 99.999% of large plankton from sea water and make constant flow-rate filtration over 100 hours without differential pressure rises. This paper explains the RC mechanism and the effect of cost-cutting for the system.
