ABSTRACT:
Chlorine dioxide is transferred by membrane pervaporation from one chamber filled with aqueous chlorine dioxide-generating reactants or other chlorine dioxide donor medium across a gas-permeable hydrophobic membrane to a recipient aqueous medium filling a second chamber. The recipient medium may be water, pulp suspension or sodium chlorite solution. The membrane typically is expanded polytetrafluoroethylene.
