PRESSURIZED-TYPE HOLLOW FIBER MEMBRANE MODULE AND FILTRATION SYSTEM COMPRISING THE SAME

摘要

Disclosed are a pressurized-type hollow fiber membrane module having a pressure resistance higher than 3 kgf/cm2 and a filtration system comprising the same. The pressurized-type hollow fiber membrane module comprises: a body case having an open end; a fixing member disposed in the body case at the open end; a hollow fiber membrane potted in the fixing member; and a cap on the open end of the body case, the cap and fixing member forming a filtrate-collecting space, wherein a lumen of the hollow fiber membrane is in fluid communication with the filtrate-collecting space, the fixing member has a step so that an upper side surface of the fixing member is not in contact with an inner surface of the body case, and a portion of the cap is inserted in a groove defined by the step of the fixing member and the inner surface of the body case.
