PURPOSE: A water treatment apparatus using a submerged hollow fiber membrane module is provided to prevent hollow fiber membrane pollution by freely moving air bubbles ascending from the lower part, and passing between a membrane module head and a module head. CONSTITUTION: A water treatment apparatus using a submerged hollow fiber membrane module comprises a suction pump(44), a hollow fiber membrane module, upper and lower guide rails(42,43), a frame(21), and a processed water channel(12). The suction pump is connected to a collector connection part(22) and a coupling hose(27) to intake processed water through the hollow fiber membrane(15). The hollow fiber membrane module comprises the hollow fiber membrane filtering processed water between the upper and lower module head. The upper and lower guide rails fix the hollow fiber membrane module. The frame is comprised with pipe manufactured for air to move, and comprises the diffuser on the lower part to generate air bubbles. The processed water channel transfers collected filtered processed water at the upper and lower part of hollow fiber membrane module head by suction of the suction pump. The air bubble transfer space is formed in the center of the upper and lower hollow fiber membrane module head. The air bubble generated from the diffuser passes through the hollow fiber membrane to prevent the pollution of the hollow fiber membrane.
