Publication number: 20020014410Abstract: 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.Type: ApplicationFiled: July 16, 2001Publication date: February 7, 2002Inventors: Michael A. Silveri, Caba Calic

Patent number: 6007693Abstract: 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.Type: GrantFiled: March 10, 1998Date of Patent: December 28, 1999Assignee: BioquestInventor: Michael A. Silveri

Patent number: 5580438Abstract: A water purifier comprising an electrolytic cell housed in an enclosure and an attaching apparatus. The enclosure attaches over an outlet fitting of a water circulation line in a swimming pool by the attaching apparatus. The attaching apparatus and the enclosure define apertures and outlet openings, respectively, having increasing areas in the direction of the water flow. This configuration increases flow rates through the apertures and outlet openings; the increased flow rates break off scale formations extending into the center of the apertures and outlet openings and thereby prevent scale from clogging the purifier. The attaching apparatus also can be coupled directly to the water circulation line and can be adjusted to accommodate fittings and circulation lines of various sizes.Type: GrantFiled: March 27, 1995Date of Patent: December 3, 1996Inventor: Michael A.

Patent number: 5359769Abstract: A method of installing a pool purifier is provided in which an existing water pipe in communication with the pool is used as a conduit for an electrical wire. The wire connects the pool purifier to a source of electricity located outside the pool to energize the pool purifier. A reel for installing the electrical wire through the water circulation line is also provided. The reel comprises a central housing and a tubular junction fitted to the housing. A spool of line is contained within a water tight chamber defined by the central housing. The other end of the tubular junction is fitted to a hole drilled in the water circulation line of a pool, and water from the circulation line is allowed to fill the chamber of the reel. The spool floats freely within the chamber as line unwinds from it and passes through the tubular junction to the water circulation line and out into the pool. The electrical wire is then fastened to the end of the line and pulled back through the water circulation line.Type: GrantFiled: July 2, 1993Date of Patent: November 1, 1994Inventor: Michael A.

Patent number: 5221444Abstract: An electrolytic pool purifier system for purifying water in a swimming pool. The system includes an electrolytic cell, located at the discharge end of a water circulation line, and a control circuit The control circuit includes a pump sense circuit for sensing the initiation of the pool pump cycle so as to maximize concurrent operation of the pump and the cell. The control circuit further includes a low current shutdown circuit for terminating operation of the system when a fault in the cell causes a reduction in control circuit current. The low current shutdown circuit includes a current monitor circuit that permits the indirect measurement of current with a voltmeter.Type: GrantFiled: November 15, 1991Date of Patent: June 22, 1993Inventor: Michael A.

Patent number: 4992156Abstract: A submerged pool purifier which has a cell including an immersed enclosure (20) to which a number of electrodes (28) are disposed in parallel array along with a masking grid (29) on each electrode. Wires (30) are routed inside existing pool piping connected to opposed electrodes on one end and a power supply (58) to the other. The wires immerge from the pool piping at a convenient location and the egress is interfaced with a compression fitting (36) making the connection watertight. The power supply changes AC electrical power to DC and a polarity reversing timer (60) reverses the polarity at regular intervals to the cell eliminating scale deposits. The DC current to the electrodes that are submerged in pool water containing dilute halite salt cause an electrolytic action ultimately producing nascent oxygen and sodium hypochlorite. In a second embodiment, the electrodes utilize a copper-silver alloy creating copper and silver ions for pool purification.Type: GrantFiled: August 18, 1989Date of Patent: February 12, 1991Inventor: Michael A.
