Abstract
A device for filtering ballast water which performs filtering by installing a filter element having a conical shape in a concentric circle direction inside the device for filtering ballast water that accommodates a filter portion, and introducing ballast water from a lower end of the device for filtering and passing same through the filter element inside the device for filtering, and for discharging backwash water containing foreign substances that are inside a filter by way of differential pressure, which is created by a driving portion communicating with a filter element by rotating a suction portion that is located on a lower end of the device for filtering. Particularly, the present invention relates to a high-efficiency candle-type device for filtering ballast water having a high-density filter structure, wherein the driving portion is positioned on a lower portion of a housing so that more filter elements can be accommodated inside the housing.
