Abstract: An apparatus for determining total hardness in a fluid stream utilizing a first and second sodium ion selective electrode (ISE). The ion selective electrodes are in electrical communication with one another, having first and second reference electrodes, respectively, with a salt bridge therebetween, where the first ISE receives hard water and the second ISE receives soft water. A least one drain receives outflow from effluent fluid from the first and second sodium ISE sensors.

Abstract: An apparatus for determining total hardness in a fluid stream utilizing an ion exchange column in a monovalent cationic form having an inlet and an outlet, where one or more monovalent ion selective electrodes are positioned either at an inlet, outlet, or at both locations simultaneously. The monovalent cation selective electrodes are in electrical communication with one another, and in fluid communication with one or more valves incorporated within a fluid path in order to introduce feed water/softened water to the monovalent cation selective electrodes. Additionally, one blending valve may be incorporated in the ion exchange column to allow a fraction of the feed (hard) water to mix with a fraction of the softened water. In this manner, the blending valve may be utilized to adjust the hardness of the water at the output.

Abstract: A method of application to provide a workable solution for tracking the hardness of water utilizing an ion selective electrode by tracking the relative hardness of water at the outflow or egress of an ion exchange column. A monovalent cation exchange membrane (ion selective electrode) distinguishes hard water and softened water in a water flow stream. A voltage is applied across the membrane, facilitating the movement of sodium though the membrane (such that anions and divalent ions are excluded), and the current is measured. The change in current (delta current) is used to determine the hard water concentration or level of hardness in an influent stream. A second application estimates or detects the exhaustion of an ion exchanger, and/or determines the regeneration time/cycle of the ion exchanger through the use of an ion selective membrane. Blending of the influent hard water and effluent soft water allows a user to control hardness levels of the effluent.

Abstract: An electrolytic zinc dosing device that regulates the amount of zinc delivered or dosed into a flowing stream of water as a function, in part, of the current applied to an electrolytic cell and the flow rate of the flowing water. A replaceable electrolytic cell having an anode and a cathode connected to a power supply, and at least one bipolar electrode in aqueous solution between the anode and cathode. Flow rate information and/or total current information are used to determine the dosing quantity of zinc delivered.
