Abstract
A system and method are disclosed for increasing the concentration of hypochlorous acid in a quantity of water. Acid is injected into chlorinated water to decrease the pH of the chlorinated water. By decreasing the pH, the hypochlorite/hypochlorous acid equilibrium of the chlorinated water is shifted to increase the concentration of hypochlorous acid on the treated water.
Claims18
A method for controlling the hypochlorite/hypochlorous acid balance of a fluid, the method comprising the steps of:
- (a) acidifying a first carrier stream to form a first mixed stream;
- (b) introducing a chlorination agent into a control stream, the chlorination agent increasing the concentration of hypochlorous acid and hypochlorite of the control stream;
- (c) combining the first mixed stream with the control stream having the chlorination agent to form a third stream, thereby reducing the pH of the control stream having the chlorination agent and increasing the relative ratio of hypochlorous acid to hypochlorite of the third stream;
- (d) monitoring chlorine levels and pH of the third stream;
- and
- (e) adjusting the first mixed stream and the control stream to maintain a desired hypochlorous acid level in the third stream.

A method for controlling the hypochlorite/hypochlorous acid balance of a control stream, the method comprising the steps of:
- (a) combining carbon dioxide with a pressurized first carrier stream to form a first mixed stream;
- (b) introducing a chlorination agent into the control stream, the chlorination agent increasing the concentration of hypochlorous acid and hypochlorite of the control stream;
- (c) combining the first mixed stream with the control stream having the chlorination agent to form a third stream, thereby reducing the pH of the control stream and increasing the relative ratio of hypochlorous acid to hypochlorite of the third stream;
- (d) monitoring chlorine levels and pH of the third stream;
- (e) adjusting the first mixed stream and the control stream to maintain a desired chlorine level and pH in the third stream.
