Abstract: An amperometric bromine control system accurately maintains a desired concentration of bromine within a home spa or in other water features. The control system employs amperometric sensing to measure the bromine concentration in the spa water and uses this measurement to control the electrochemical production of bromine through the oxidation of aqueous bromide. The level of bromide in the spa water desirably is greater than 50 ppm in order to obtain a linear relationship between the current level sensed through the amperometric measurement and the concentration level of bromine in the water. In this manner, the control system can accurately measure the bromine concentration in the spa water and precisely maintain the bromine concentration within a desired range between about 2 ppm and 6 ppm.

The level of bromide in the spa water desirably is greater than 50 ppm in order to obtain a linear relationship between the current level sensed through the amperometic measurement and the concentration level of bromine in the water. In this manner, the control system can accurately measure the bromine concentration in the spa water and precisely maintain the bromine concentration within a desired range between about 2 ppm and 6 ppm.

Abstract: A halogen generator produces a halogen sanitizing agent to sanitize water in a spa or other water feature. A coaxial wall fitting desirably couples the halogen generator to the water feature. The halogen generator desirably includes a bipolar electrolytic cell in which a center electrode plate rotates between stationary anode and cathode plates. The bipolar electrode includes a plurality of vanes which motivate water flow between the anode and the cathode. The vanes on the rotating electrode also produce a flow of water through the generator. In this manner, the bipolar electrode functions as a impeller to pump water through the halogen generator. The vanes are positioned between the electrode and cathode, and are sufficiently spaced from the cathode to inhibit scale formation on the cathode. The vanes, however, generally do not contact the cathode when rotating.
