G06F017/00

US Classification:

705/412000

Abstract:

Methods and systems are disclosed for determining water usage for industrial facilities and residences. One method communicates with a communications network and acquires water usage information. The water usage information is acquired in real time. The method reports water usage based upon the acquired water usage information. Another embodiment acquires water usage information over a communications network. This embodiment acquires real time water usage information over the communications network at a computer. The water usage information is associated with water use of an industrial facility. The embodiment may then display the real time water usage information via a user interface on the computer.

Assignee:

General Electric Company - Niskayuna NY

International Classification:

C02F001/42

US Classification:

210/662000

Abstract:

Regeneration controller and method for controlling regeneration of a water softener are provided. The controller includes a water meter configured to output a signal indicative of the volume of influent water received by the water softener. A water-hardness indicator, such as a conductivity meter or ion-selective electrode, is configured to output a signal indicative of a degree of hardness of the influent water. A processor is coupled to receive the respective signals from the water meter and the hardness indicator. The processor is further configured to calculate a value indicative of the total level of hardness removed by the water softener. A comparator is coupled to receive a signal indicative of the quantity of resin capacity of the water softener. The comparator is further configured to receive the value indicative of total hardness to issue a regeneration command based on comparing the resin capacity relative to the value of total hardness.

Abstract:

A unitary water filter assembly and method for removing all microbiological and multiple types of chemical contaminants from water used in an appliance for human consumption are provided. The filter assembly includes a first filter stage fluidly coupled to receive influent water for filtering chemical contaminants therein. A second filter stage is fluidly coupled to the first filter stage for filtering microbiological organisms therein. The filter assembly allows removal of all microorganisms such as cysts, bacteria, bacterial spores and viruses, from the drinking water. The filter assembly may also be configured to remove chemicals, such as chlorine, including associated taste and odor with such chemicals, particulates, and metal contaminants from drinking water. The filter assembly may be further configured to remove volatile organic compounds (VOCs), and other organic and inorganic contaminants from drinking water.

Abstract:

System and method for purifying and recycling spent brine in a water softener are provided. The system may be made up of a cation exchange resin tank fluidly coupled for passing spent brine comprising monovalent and divalent ions. A fluid mixer valve is coupled to the resin tank and to a water tank to dilute the spent brine to a desired concentration of a regenerant salt, e.g., NaCl. An ion-separation device is fluidly coupled to the fluid mixer valve to receive the diluted spent brine and separate the diluted spent brine into first and second streams. The first of the streams comprises monovalent ions and the second of the streams comprises divalent ions.
