Abstract
A module for ultrafiltration or microfiltration of water includes hollow fibers, of the type of filtration from outside inwards of the fibers, the water to be treated being introduced at the top of the module and the treated water being collected at the bottom of the module. The fibers are arranged inside a housing in multiple U-shaped bundles, the module being vertically arranged in use with the U-shape in the top part of the module. At the bottom of the module, each bundle is arranged in a sheath and individually potted. The sheaths are then urged to be housed in a distribution plate, and all the sheaths are interconnected by pouring (in reverse vertical position relative to that of the filtering mode) a potting resin.
