BACKFLUSH FILTER, IN PARTICULAR FOR WATER FILTRATION AND METHOD FOR BACKFLUSHING THEREOF

The invention relate to a backflush filter, in particular for water filtration. The cleaning device for the backflush filter comprises a flushing arm (25), connected to the upper perforated plate (21) of a filter set (20) and a second flushing arm (35), connected to the lower perforated plate (31). The flushing arms (25, 35) each comprise a hollow flushing member (27, 37) and also a sealing member (28, 38). The flushing arms (27, 37) and sealing members (28, 38) are arranged at an offset of 180 DEG to each other so that the cleaning device may be used for time-shifted and counter-flow backflushing. The filter element (22') is connected to ambient pressure by means of the flushing member (27) and the outlet valve (50). The upper input end (24') of the filter element (22') is then sealed by means of the sealing member (28). At a later point in time the upper input end (24') is connected to ambient pressure by means of the flushing member (27). In the case of electrical drive the drive energy may be provided by means of a solar panel (57).
