Abstract: A water treatment system, such as a water softening system, having a water treatment tank with at least one distributor plate mounted inside to support filter media and/or ion exchange resin. The water treatment system is designed to treat hard water with a packed ion-exchange filter media and has a distributor plate design for facilitating the ion-exchange within a water softener resin bed, as well as facilitating the regeneration of the resin bed. The distributor plate presents cavities to the topside for entrapping filter media, and the cavities have narrow slits located at the base for allowing fluid to pass. A method for assembling the water treatment tank and supporting inserted distributor plate is shown. The distributor plate rest on and is supported by a domed-shaped structure that can be placed in the bottom portion of the water treatment vessel.

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: A fluid treatment system and method of aligning and securing mechanical components within the system. The system comprises a container base with vertically extending sidewalls forming a sump, and a tank retainer disposed on the base within the sump. A system plate encapsulates the sump, and may include a bridge member projecting from the plate's top surface. A media bottle's bottom surface is placed within the tank retainer, and the media bottle's neck is received by an annular collar of the system plate such that the media bottle is secured within the system and movement of the media bottle within the sump is inhibited and/or restricted.

Abstract: A sensor system and process that utilizes impedance/conductivity measurements to track the movement of hardness in an ion exchange media. The impedance/conductivity sensor is a vertical, longitudinally directed, axially lengthwise electrode system having electrodes placed within a bed of ion exchange material and separated by water and the ion exchange material. The electrodes generally run parallel to one another. Hard water is introduced to the water softener and softened by the ion exchange material. A hardness gradient is tracked by the sensor, and regeneration is initiated when it is determined that the ion exchange material is depleted or exhausted.

Abstract: A proportioning valve for a reverse osmosis system that controls the production of product water by the differential pressure across the purification membrane. By sensing increasing tank pressure to actuate the proportioning valve, the flow of waste water is restricted. Placement of seals within the cavity of the valve, as well as placement of waste water inlet and outlet ports, protects tension components that provide reverse tank pressure from waste water exposure. A needle valve assembly responsive to an actuating assembly that senses tank pressure removes the need for an inlet tank water port while restricting water flow.

Abstract: A modular filtration platform having at least one manifold head and at least one respective filter cartridge assembly. Each manifold head is connected to one another to establish a water flow in a series or parallel manner. Each filter cartridge assembly is releasably secured from rotation relative to the manifold head by a locking mechanism. An aperture on the filter cartridge assembly annular collar mates with a protruding resilient extension on either the manifold head or support bracket. Alternatively, an aperture on the filter cartridge assembly annular collar and an aperture on the manifold head annular collar mate with a protruding member from a locking ring extending through both apertures. An integrated sensor package may be integrated with the system for true managed water visible/audible indications and Wi-Fi interface to facilitate virtually instantaneous response times for filtration needs.
