Abstract

A membrane module has a first solid body having a plurality of passages extending through it and a second solid body. Hollow fiber membranes extend between the solid bodies. A permeate manifold communicates with the lumens of the membranes through their ends. The membranes are arranged into a plurality of spaced bundles in the first solid body. A passage is located between adjacent bundles. An apparatus for withdrawing permeate from a substrate has a membrane module immersed in a tank containing a substrate at ambient pressure. The module is oriented such that the solid bodies are generally vertically aligned with the second solid body above the first solid body. A source of suction is connected to the permeate manifold for withdrawing permeate. A gas distribution system supplies a gas to the passages through the first solid body. The gas may be provided continuously or intermittently during permeation.
