METHOD AND APPARATUS FOR TREATING WATER CONTAINING ORGANIC MATTER

摘要

A method and apparatus for treating water containing organic matter that would inhibit any microbial multiplication in active carbon column and reverse osmosis membrane separator and attain stable treatment over a prolonged period of time in the flow including active carbon treatment and post-stage RO membrane separation treatment of an ultrapure water production system for use in electronic device manufacturing plants. The method for treating water containing organic matter comprises the oxidizer addition step of adding an oxidizer to water containing organic matter; the active carbon treatment step of treating the water containing organic matter having undergone the oxidizer addition step with active carbon; and the reverse osmosis membrane separation step of passing the water containing organic matter having undergone the active carbon treatment step through reverse osmosis membrane separating means, wherein a chlorinated oxidizer is used as the oxidizer.
