Abstract

In accordance with aspects and embodiments, a filtration system is provided comprising a membrane module comprising an upper header and a lower header, a plurality of hollow fiber membranes having an upper end potted in the upper header and a lower end potted in the lower head, a cage at least partially surrounding the plurality of hollow fiber membranes, and a screen in contact with and surrounding the cage, the filtration system further comprising an aeration cap coupled to the lower header of the membrane module. The screen may protect the hollow fiber membranes from damage from coarse contaminants contained in the feed liquid, may improve module integrity, and may improve the efficiency of the filtration system.
