The filtering vessel (1) holding cartridge filter (16) is connected to a receiver (3) through a quick-opening valve. There is generated an underpressure in (3) for separating the filter cake built up on the cartridges, said underpressure being lower than the evaporation pressure of the liquid contained in the filter cake. Accordingly, there is built up an overpressure in the filtering vessel (1). An immediate opening of the valve (2) and a proportionate temperature in system (1) and (2) results in a spontaneous bursting off of the filter cake from the cartridge surface, which bursting off, in consequence of the pressure compensation between (1) and (3) still will be increased by means of the liquid contained in the filter cake evaporating in the course of a flash procedure. The relatively dry filter cake is collected in the receiver (3). The next filtration process can be started after closing valve (2).
