Hollow fiber membrane module, filtration apparatus using the same, and method for manufacturing the filtration apparatus

A filtration apparatus comprising:

• a hollow fiber membrane module including a header having a projecting port for discharging out permeate water in a permeate collecting unit and a bundle of hollow fiber membranes of which ends are potted in potting surface of the header so that the hollow fiber membranes are in fluid communication with the permeate collecting unit;
• and
• a unit pipe providing a pathway for the permeate water discharged from the projecting port, the projecting port being inserted into the unit pipe,
• wherein the header has first and second sides adjacent to the potting surface and opposite to each other, and
• wherein grooves extended in a length direction of the hollow fiber membranes are formed on the first and second sides.

A filtration apparatus comprising:

• a first hollow fiber membrane module having a first header provided with a first groove;
• a second hollow fiber membrane module having a second header provided with a second groove;
• and
• a slide rod,
• wherein the slide rod includes a first main body inserted into the first groove, a second main body inserted into the second groove, and a link unit positioned between the first and second main bodies.
