Abstract
A water treatment apparatus for removing dissolved oxygen contained in water to be treated includes: an anode; a cathode; and a dissolved oxygen removal chamber which is located between the anode and the cathode and filled with an ion exchanger. At least a portion of the ion exchanger filled in the dissolved oxygen removal chamber is an ion exchanger on which a metal catalyst is supported. The ion exchanger on which the metal catalyst is supported is filled in a single bed configuration in at least a portion of the dissolved oxygen removal chamber. A DC current is applied between the anode and the cathode.
Claims20
A water treatment method for removing at least dissolved oxygen contained in water to be treated, comprising:
- applying a DC current between an anode and a cathode;
- and
- passing the water to be treated through a dissolved oxygen removal chamber, which is located between the anode and the cathode and filled with an ion exchanger,
- wherein at least a portion of the ion exchanger filled in the dissolved oxygen removal chamber is an ion exchanger on which a metal catalyst is supported, and
- wherein the ion exchanger on which the metal catalyst is supported is filled in a single bed configuration in at least a portion of the dissolved oxygen removal chamber.
A water treatment method for removing at least dissolved oxygen contained in water to be treated, comprising:
- applying a DC current between an anode provided in an anode chamber and a cathode provided in a cathode chamber which is filled with an ion exchanger;
- and
- passing the water to be treated through the cathode chamber,
- wherein at least a portion of the ion exchanger filled in the cathode chamber is an ion exchanger on which a metal catalyst is supported.
A water treatment apparatus for removing at least dissolved oxygen contained in water to be treated, comprising:
- an anode and a cathode;
- and
- a dissolved oxygen removal chamber which is located between the anode and the cathode and filled with an ion exchanger, and through which the water to be treated passes,
- wherein at least a portion of the ion exchanger filled in the dissolved oxygen removal chamber is an ion exchanger on which a metal catalyst is supported,
- wherein the ion exchanger on which the metal catalyst is supported is filled in a single bed configuration in at least a portion of the dissolved oxygen removal chamber, and
- wherein a DC current is applied between the anode and the cathode.
A water treatment apparatus comprising:
- an anode chamber equipped with an anode;
- and
- a cathode chamber equipped with a cathode, filled with ion exchanger, and supplied with water to be treated,
- wherein at least a portion of the ion exchanger filled in the cathode chamber is an ion exchanger on which a metal catalyst is supported, and
- wherein a DC current is applied between the anode and the cathode.
