PURPOSE:To efficiently perform water-intake with an apparatus having a simple structure by operating a pump and a motor simultaneously and performing water-intake operation, scouring of the filter face of an element, transfer and discharge of solid matters in a parallel and continuous manner. CONSTITUTION:When starting a pump 3 and a motor 8, solid matter having comparatively large particle diameter contained in raw water is trapped with a guard 7 and thereafter raw water is introduced into an element 3 via a water- passing aperture part of the guard 7 and an inflow port 10 for raw water of the element 3 and passed through the water-passing holes of the elements 3 and made into clean water, and this is sucked into a pump 41 via an outflow port 11 of filtrate and a suction pipeline 44 and fed to be used for prescribed applications. Meanwhile a part of the solid contained in raw water is once trapped with the element 3 but peeled off with brushes of a sweeping member 4, and also the filter face of the element 3 is scoured with the brushes. The above trapped and peeled solid matter and the other solid matter are successively transferred with screw blades 6 and discharged to the outside of the element 3 through a discharge port 12.
