Abstract: 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.

Abstract: Disclosed are an extendable pressurized-type hollow fiber membrane module which facilitates improvement of filtrate quality through a multistep-filtration, enhanced easiness of installation and maintenance, decrease of footprint, and/or enlargement of filtration apparatus (without causing decrease of permeate flux of a unit hollow fiber membrane), and a filtration apparatus manufactured using the same. The filtration apparatus of the present invention comprises first and second pressurized-type hollow fiber membrane modules, wherein an inlet port of the first pressurized-type hollow fiber membrane module for introducing feed water and an outlet port of the second pressurized-type hollow fiber membrane module for discharging filtrate or air are coupled to each other.
