The present invention relates to a device for filtering for treating ballast water by means of a filtering method, and to a method for controlling same, and more particularly, to a multicage-type device for filtering ballast water which automatically controls sequential backwashing and a method for same. In the multicage-type device for filtering ballast water, an automatic cleaning portion in each filtering device, in which differential pressure of at least a specific range with respect to pressure inside a body is generated, from a plurality of filtering units in the device for filtering, is sequentially actuated under the control of a control portion, thereby allowing smooth backwashing by preventing increase of back pressure during backwashing of foreign substances, and increasing repair/maintenance efficiency by installing a second pressure sensor for measuring pressure inside a filter in each of the filtering units via a pressure measurement aperture that penetrates an upper portion cover plate that covers a filter inlet aperture on an upper portion of the body.
