Abstract
A filter vessel is partitioned into a first, second and third compartments with upper and lower watertight partitions. A plurality of hollow fiber modules each having upper and lower filtrate outlet ports are vertically disposed in the second compartment, and upward-detachably fixed in the filter vessel. Each hollow fiber module is watertightly joined with a lower water collection tube communicating with the third compartment by means of a jointing means capable of vertical elastic movement. Feed water fed into the second compartment is filtered through walls of porous hollow fibers in the hollow fiber modules into the bores of the porous hollow fibers, through which the filtrate is conducted into the first compartment via the upper filtrate outlet ports of the hollow fiber modules as well as into the third compartment via the lower filtrate outlet ports of the hollow fiber modules and lower water collection tubes joined with the respective hollow fiber modules. The filtrate collected in the first and third compartments is then discharged therefrom out of the filter column.
