PROCESS AND APPARATUS FOR REMOVAL OF HYDROGEN PEROXIDE, PROCESS AND APPARATUS FOR PRODUCTION OF OZONIZED WATER, AND METHOD AND APPARATUS FOR WASHING

摘要

A process for the removal of hydrogen peroxide which comprises passing intermittently hydrogen peroxide-containing water through an ion exchange unit filled with an OH-form anion exchanger. Alternatively, hydrogen peroxide-containing water may be passed by turns through plural ion exchange units arranged in parallel. The ion exchange unit may take the form of a single bed of an OH-form anion exchanger. The OH-form anion exchanger may be a strongly basic anion exchanger.
