STACK TYPE MEMBRANE MODULE

摘要

An improved membrane module is provided to apply the membrane module to sewage or wastewater with a high silt density index and improve the treatment efficiency of the sewage or wastewater. A stack type membrane module(100) comprises: a housing(110); a plurality of spacers(120) which are stacked in the housing, and each of which has a hollow hole formed in a central portion thereof and a plurality of slits formed in an outer face of the hollow hole; membranes(130) which are interposed between the spacers, and each of which has a hollow hole formed in a central portion thereof such that the hollow hole of the membrane communicates with the hollow hole of the spacers; an inflow pipe(150) connected to a lower part of the housing to provide a path for flowing sewage or wastewater into the housing; a collector(140) connected to the lower part of the housing to collect treated water filtered by the membranes in the sewage or wastewater; a treated water discharge pipe(160) connected to the collector to discharge the collected treated water; and a concentrate discharge pipe(170) connected to the spacers to discharge concentrate discharged through the slits. Further, the housing is made of a GRP(glass reinforce plastic).
