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.

Longitudinal in-situ impedance and resin monitoring sensor, and method of measuring and tracking the movement of hardness in a water softener utilizing the same

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.

Water treatment tank with distributor plate assembly and method of assembly

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.

Electrolytic zinc dosing device and method for reducing scale

A system to increase the water recovery ratio and efficiently save water in a water treatment and delivery system, particularly for a water treatment system that may be used for water softening, and more particularly for a water treatment system that employs capacitive deionization technology. Stored product water is delivered without the implementation of an additional pump, and the stored product water is used to recover water in a storage tank without having to send water to drain.
