Abstract:
The present invention relates to a method and system for controlling the correct operation of a salt water chlorinator and determining if the flow and salinity parameters thereof are suitable, where said method includes the steps of providing a constant current to the electrodes, measuring the value of the voltage in the electrodes and storing said value, subsequently measuring the value of the voltage in the electrodes, comparing the stored value of the voltage with the value of the voltage taken periodically, and where appropriate, notifying the user that there is a problem in the flow or with the salt, as well as calculating the salt input needed to be input by the user or by automatic means so that the chlorinator goes back to operating in an optimal manner.
Abstract:
A robotic pool cleaner (10) having an exterior housing and an electrochemical chlorine generator assembly mounted inside the housing. The electrochemical chlorine generator assembly comprises a plurality of conductive electrodes operatively connected to generator terminals for receiving power from a power source, a case (30) constructed of a non-conductive material in which the plurality of electrodes are mounted. The case (30) has passages for the movement of pool water across the chlorine·generating surfaces of the electrodes. The case (30) further comprises mounting means (124,126) on the case (30) for securely engaging corresponding receiving means (140, 142, 144, 146) on a structural member (150) of the pool cleaner housing for securing said electrochemical chlorine generator assembly in an operable position in which said generator terminals are in mating contact with power conductors mounted in said pool cleaner (10). The case (30) also comprises manually releasable engagement surfaces for separating said mounting (124,126) and receiving means (140, 142, 144, 146) to thereby permit removal of the electrochemical chlorine generator assembly from the interior of the pool cleaner housing.
Abstract:
Provided are electrochemical devices that are rechargeable, where an electrolyte stream whose electrolyte is electro-chemically inert is supplied to an ion concentrate compartment between a bipolar membrane and an electrode, thereby eliminating a potential for scale build-up. When strong or weak cation resins are used in a product compartment of an electrochemical device, acid water produced can be used to soak and clean an ion concentrate compartment next to an electrode, such as the cathode.

Abstract:
A water treatment method for improving the water quality of a body of water is disclosed. A water treatment mineral is also disclosed, The water treatment mineral includes a third period electrolyte component comprising magnesium chloride and sodium chloride. The magnesium chloride is more than about 15% by weight of the third period electrolyte. The water treatment mineral may be used with existing water treatment equipment by adjusting the concentration to a level suited to the effective production of hypochlorite anions at a concentration sufficient to sanitize the water, The method includes adding the water treatment mineral to the body of water at a concentration of about 1200 ppm to about 9600 ppm. The water is passed through an electrolytic cell and an electrical potential is applied, sufficient to produce a predetermined concentration of hypochlorite anions in the mineralized water passing through the electrolytic cell to produce chlorinated water, The chlorinated water is then returned to the body of mineralized water.
