The present invention relates to a multicage-type apparatus for filtering ballast water in which a plurality of filtering units are packetized and connected inside a body from which ballast water is introduced or discharged, and to a method for same, and more specifically, to a multicage-type apparatus for filtering ballast water for automatically controlling simultaneous reverse-washing and to a method for same, the multicage-type apparatus for filtering ballast water comprising filters for filtering the ballast water that flows inside the body, and an automatic cleaning portion for reverse-washing foreign substances which adhere to the filter. The multicage-type apparatus for filtering ballast water further comprises on the exterior of the filters a first pressure sensor for measuring the pressure inside of the body, and a second pressure sensor, which is installed on a portion of the filtering units from among the plurality of filtering units, for measuring the pressure inside the filter of each of the filtering units, wherein all of the automatic cleaning portions of the plurality of filtering units are driven to reverse-clean the foreign substances that adhere to the filter, when the difference in a value measured by the second pressure sensor and the value measured by the first pressure sensor exceeds a predetermined range, thereby improving the efficiency of removing the foreign substances.
