Backwash tanks (42) having upstream backwash valves (38) and downstream backwash valves (40) are installed in backwash pipes (32) through which the high-pressure gas is guided from high-pressure-gas supply equipment (30) to backwash nozzles (34) for ejecting the backwash high-pressure gas toward the filter group to form a backwash high-pressure-medium supply line. The outlet pressure of the high-pressure-gas supply equipment (30) is set to "1 / critical pressure ratio" or more times a filter inlet gas pressure so that the flow speed of the high-pressure gas ejected from the backwash nozzle (34) is the speed of sound or higher.
