Abstract: 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.

Abstract: A fluid filtering apparatus such as for filtering particulates and other materials from treated water includes a tank and a filtering region configured as a plurality of individual effluent regions, defined in part by channel frames, disposed between a plurality of influent regions interposed between the effluent regions. A double sided backwash shoe is scannable in the influent regions, to simultaneously clean opposed filter media exposed thereto. The backwash shoe is free to move inwardly and outwardly of the opposed filter media. Additionally, the backwash shoe includes an end opening, positioned adjacent to the base of the tank, to remove sludge and particulates which have settled to the area near the base of the tank while backwashing a filter media.
