Publication number: 20190177184Abstract: A contact chamber in which a bed of fluid treatment media is fully fluidized by using a fluidizer. The fluidizer may be, for example, an internal or external eductor that acts as a pump for a media and fluid mixture to boost fluid flow and generate recirculation that keeps the media suspended in the fluid or an arrangement of nozzles, mixing blades, pumps, baffles, or irregular cross-sectional shapes (or combinations of any of these) to promote fully fluidizing the media in the chamber and causing the media to recirculate within the chamber.Type: ApplicationFiled: July 13, 2017Publication date: June 13, 2019Inventors: David J.

Patent number: 9695070Abstract: Embodiments of the invention provide a method of regenerating a capacity of a flow-through capacitor. A target value for a water property concentration in a discharge water stream exiting the flow-through capacitor is established. A feed value for the water property concentration in a feed water stream entering the flow-through capacitor is measured. An amount of the water property concentration to be added to the feed water stream is calculated based on the feed value to achieve the target value for the water property concentration in the discharge water stream. An amperage of the flow-through capacitor and a flow rate through the flow-through capacitor is controlled to add ions to the feed water stream to achieve the target value for the water property concentration in the discharge water stream. In some embodiments, the amperage can be set and the flow rate controlled to achieve the target concentration.Type: GrantFiled: October 27, 2011Date of Patent: July 4, 2017Assignee: Pentair Residential Filtration, LLCInventors: David J. Averbeck, Rebecca M. Tallon, Brett A. Boedeker

Patent number: 9637397Abstract: Embodiments of the invention provide methods of removing ions from a feed water stream using a flow-through capacitor and a controller for performing the methods. A target value for a water property concentration or a fixed percent removal of a water property concentration to be removed is established for a treated water stream exiting the flow-through capacitor. A feed value for the water property concentration is measured in a feed water stream entering the flow-through capacitor. An amperage of the flow-through capacitor and a flow rate through the flow-through capacitor is controlled to remove ions from the feed water stream to achieve the desired removal of the water property.Type: GrantFiled: October 27, 2011Date of Patent: May 2, 2017Assignee: Pentair Residential Filtration, LLCInventors: David J.

Patent number: 9302920Abstract: Integrated controller and method for a water filtration system. The system can include a membrane filter, a valve coupled to the membrane filter, and a water softener and/or a media filter. The filtration system can include a controller coupled to membrane filter and coupled to the water softener and/or the media filter. The controller can include a flow meter and a switch. The flow meter can be coupled to the membrane filter and the water softener and/or the media filter. The switch can be electrically connected to the valve.

Patent number: 8961770Abstract: Embodiments of the invention provide a method of operating a flow-through capacitor and a related controller for performing the method. The method includes establishing a summed-current capacity of the flow-through capacitor. In an operational cycle, the flow-through capacitor is operated to transfer ions between the pair of electrodes and water. A current is monitored during operation of the flow-through capacitor. This current is integrated over time to calculate a monitored-current value. To determine an end of the operational cycle, the monitored-current value is compared to the summed-current capacity.Type: GrantFiled: October 27, 2011Date of Patent: February 24, 2015Assignee: Pentair Residential Filtration, LLCInventors: David J.
