Title:
CROSS-LINKED CATALASE IMMOBILIZED FIBER AND ULTRAPURE WATER PRODUCING APPARATUS
Document Type and Number:
Japanese Patent JP2013237944
Kind Code:
A
Abstract:

To provide new hydrogen peroxide decomposition means that can be inexpensively obtained, and to provide an ultrapure water producing apparatus provide with the new hydrogen peroxide decomposition means.

The ultrapure water producing apparatus comprises: a pretreatment device (A) of raw water; a primary purified water producing device (B); a secondary purified water producing device (C) including a low-pressure ultraviolet oxidation device; and further a hydrogen peroxide decomposition device arranged after the low-pressure ultraviolet oxidation device, and uses a cross-linked catalase immobilized fiber as a decomposition catalyst in the hydrogen peroxide decomposition device.
