Abstract
An apparatus for dehalogenating an aqueous salt solution may include a tank, an electrode pair positioned at least partially within the tank, and an aerator positioned at least partially below an anode of the electrode pair. An inlet of the tank may be configured to introduce the aqueous salt solution into the tank, and as the aqueous salt solution contacts the electrode pair that may include a voltage potential between the anode and cathode, electrolysis occurs and the halogens in the aqueous salt solution, e.g. chloride, may be oxidized at the anode. The aerator may be configured to sweep the halogens to the top of the tank.
Claims20
An apparatus for dehalogenating an aqueous salt solution, comprising:
- a tank comprising:
- an inlet configured to introduce the aqueous salt solution into the tank, and
- an outlet configured to remove a dehalogenated aqueous solution from the tank;
- at least one electrode pair positioned at least partially within the tank, wherein each electrode pair comprises an anode and a cathode that are configured to be at least partially submerged in the aqueous salt solution, and wherein each electrode pair is configured to have a voltage potential between the anode and the cathode;
- and
- an aerator positioned at least partially below the anode.
A system for purifying water, comprising:
- a first tank comprising:
- an inlet configured to introduce an aqueous salt solution into the first tank,
- a plurality of electrode pairs positioned at least partially within the first tank and positioned along a length of the first tank, wherein each of the plurality of electrode pairs comprises an anode and a cathode that are configured to be at least partially submerged in the aqueous salt solution, wherein each of the plurality of electrode pairs is configured to have a voltage potential between the anode and the cathode,
- an aerator positioned at least partially below at least one anode, and
- an outlet configured to remove a dehalogenated water from the first tank;
- and
- a second tank comprising:
- an inlet configured to receive the dehalogenated water removed from the first tank,
- an acid dispenser configured to add a mineral acid into the second tank, and
- an outlet configured to remove purified water from the second tank.
A process for dehalogenating an aqueous salt solution, comprising:
- introducing an aqueous salt solution into a first tank that includes an electrode pair comprising an anode and a cathode;
- generating a voltage potential between the anode and the cathode to decompose a salt in the aqueous salt solution to produce a halogen gas;
- and
- bubbling a gas in the aqueous salt solution via an aerator positioned at least partially below an anode of the electrode pair.
