Abstract

In a dewatering system water containing contaminants is removed from a gas or liquid stream and then processed to separate the water from the contaminants. The water is separated using a condenser and a semi-permeable membrane in the form of tubing through which the water permeates so that it is prue enough to be disposed-of in the local environment by evaporation. The contaminants accumulated in the tubing may be removed separately for controlled disposal, and/or reintroduced into the original stream by connection of he tubing to the input end of the dewatering system.
