Summary:PROBLEM TO BE SOLVED: To keep the treatment performance while reducing attachment of screenings when filtering liquid flows inside a membrane module, as solid-liquid separation is applied by vertically soaking the membrane module formed by bundling hollow fiber membranes into the filtering liquid. SOLUTION: The membrane module 10 includes an upper fixing part 30 holding upper ends of the hollow fiber membranes 20, and a lower fixing part 40 holding lower ends. The upper fixing part 30 is provided with an upper opening 31 vertically penetrating therethrough for passing an upward flow C of the filtering liquid, and the lower fixing part 40 is provided with a lower vent hole 42 vertically penetrating therethrough for passing air jetted from an air feed means, so that an amount of the filtering liquid flowing along the lower face of the upper fixed part 30 is reduced to suppress the attachment of screenings.
