ABSTRACT:
An apparatus for producing a purified aqueous hydrogen peroxide solution. The apparatus includes at least one purifier tower packed with an ion exchange resin, a chelate resin or an adsorption resin for receiving a charged aqueous hydrogen peroxide solution containing impurities so as to effect contact thereof with the ion exchange resin, chelate resin or adsorption resin, thereby purifying the charged aqueous hydrogen peroxide solution, which apparatus further comprises a feed pump of given output capable of causing the charged aqueous hydrogen peroxide solution to flow to the purifier tower, a flow sensor capable of sensing a flow rate of charged aqueous hydrogen peroxide solution being fed to the purifier tower by means of the feed pump, and a flow control unit capable of controlling the output of the feed pump on the basis of a detection result of the flow sensor so as to maintain the flow of charged aqueous hydrogen peroxide solution being fed to the purifier tower at a constant rate.
