The present invention relates to an a multi-cage type ballast water filtering apparatus having a function of automatically controlling simultaneous backwashing, and a method of automatically controlling the simultaneous backwashing. The apparatus includes a body, and filtering units connected to each other to form a packaged structure in the body. Each filtering unit includes a filter filtering ballast water, and an automatic washing unit backwashing the filter. The apparatus further includes a first pressure sensor measuring the pressure in space between the body and the filters, and a second pressure sensor installed on each of some of the filtering units to measure the pressure in the filter of the corresponding filtering unit. When a difference between pressures measured by the first and second pressure sensors exceeds a predetermined range, the automatic washing units of all of the filtering units are simultaneously operated.
