摘要：PURPOSE:To reduce a volume per unit capacity by enhancing filtering efficiency and to make a filter compact by always using the entire surface of a screen in solid-liquid paration or the movement of a solid in a lumpy state. CONSTITUTION:Liquid sump parts 6 are provided on both left and right sides of a filtering screen 10 depresd in a circular cross-ctional shape at the central part thereof and having a shape opened in an oblique upward direction on both left and right sides. Overflow weirs 12 are formed to the upper ends of the screen 10 on both left and right sides thereof over the almost total length thereof so as to allow raw water W to be treated to overflow from the liquid sump part 6 to the filtering screen 10. Further, a continuous spiral blade type feed apparatus 8 is arranged to the upper surface of the central part of the screen 10 along the longitudinal direction thereof and, furthermore, a filtrate receiving part 8 is formed under the screen 10. As a result, this filter becomes highly efficient and can be made compact and the maintenance and inspection thereof become easy.户太八号
