Abstract
The present invention provides a gas/liquid contactor module having hollow fiber membranes and a process for controlling dissolved gases in liquids such as water, beer and the like, by passing the liquid through the shell side of the contactor module to allow addition or removal of dissolved gases by the diffusion of the gases through the membranes into or from the hollow fiber bores. The process permits control of the quantity of such dissolved gases as carbon dioxide and nitrogen.
