Filtration equipment for hollow fiber module

Filtration equipment comprising a filter vessel, a number of hollow fiber modules each having upper and lower filtrate outlet ports and vertically disposed and individually upward-detachably fixed in said filter vessel, a common upper filtrate collection compartment provided in an upper part of said filter vessel and communicating with the upper filtrate outlet ports of said number of said hollow fiber modules, a plurality of lower manifolds each fluid-tightly joined with a plurality of hollow fiber modules and set on the lower filtrate outlet ports thereof by means of respective jointing means capable of vertical elastic movement and each provided for one hollow fiber module, each lower manifold being provided with at least one conduit communicating with said common upper filtrate collection compartment for conducting the filtrate outlet ports of said plurality of the hollow fiber modules into said common upper filtrate collection compartment;

• an inlet connected to said filtering vessel, and wherein fluid fed into said filter vessel through said inlet is filtered through the walls of porous hollow fibers in the hollow fiber modules, while the filtrate is conducted into said common upper filtrate collection compartment via said upper filtrate outlet ports of said hollow fiber modules as well as via the lower filtrate outlet ports of said hollow fiber modules, said lower manifolds and conduits thereof, and the filtrate collected in said common upper filtrate collection compartment is then discharged therefrom out of the filter vessel.
