A water screen comprises a revolving screen member, e.g., a band screen or a drum screen, and a washing device. The washing device, comprises a sprayer on one side of the downstream run of the screen member and a recovery channel on the opposite side of the downstream run of the screen member. On the same side as the recovery channel and between it and the sprayer is a mobile trough member. The trough transversely and obliquely from its leading edge adjacent the recovery channel, e.g. a band screen or a drum screen. The leading edge of the trough is maintained continuously in contact with the screen member which may be exclusively by the effect of gravitational force on the trough member.
