SUBMERGED HOLLOW FIBER MEMBRANE MODULE AND SUBMERGED FILTERING APPARATUS

摘要

PURPOSE: A submerged hollow fiber membrane module and a submerged filtering apparatus including the same are provided to prevent the deposition of suspended materials on the surface of membranes and the reduction of flux at the upper side of the module. CONSTITUTION: A plurality of submerged hollow fiber membranes(30) is fixed to a housing in a submerged hollow fiber membrane module. The submerged hollow fiber membrane module includes an upper header(10), a lower header(20), the hollow fiber membranes, and central protrusions. The upper header and the lower header are parallelly arranged. The hollow fiber membranes are vertically arranged between the headers. The central protrusions are conically formed at the upper center of the submerged hollow fiber membrane module and are integrated with the upper header.
