Abstract
A membrane filtration module having a plurality of permeable, hollow membranes is disclosed. In use, a pressure differential is applied across the walls of the permeable, hollow membranes when immersed in a liquid suspension containing suspended solids. Some of the liquid suspension passes through the walls of the membranes to be drawn off as clarified liquid or permeate, and at least some of the solids are retained on or in the permeable, hollow membranes or otherwise as suspended solids within the liquid suspension. The module has a shell or similar structure that at least partially surrounds the membrane module and substantially effects retaining at least portion of fluid flowed into the membrane module.
