Hollow fiber filter device

摘要

A hollow fiber filter device has a plurality of fiber filter modules suspended therein, the filter module being improved in rigidity and arranged to be easily handled while minimizing the risk of being damaged by securing the opposite ends of hollow fibers of the hollow fiber bundle to two bundle plates and by extending a central pipe from one of the bundle plates through the other of the bundle plates, the module being encased within a protecting hollow cylinder with perforated walls.
