ABSTRACT:
In addition to health implications, trihalomethanes (THMs) poses a challenge to the electronic industry where such impurities cannot be tolerated. A process is provided for removing THMs from high-purity water used in the electronic industry. The method of the invention comprises contacting the high-purity water with a membrane degassifier, preferably operating at a temperature exceeding 45° C.
