  • Patent number: 10214931
    Abstract: A pre-filter skimmer system that reduces the amount of debris and particles entering the water filter in order to increase the longevity of the water filter is disclosed. The pre-filter skimmer system includes a chamber including an inlet and an outlet, wherein the water enters via the inlet and exits via the outlet. The water enters a first collector that is positioned at least partially within the chamber, the first collector configured to capture particles of a first size carried by the water. From here, the water enters a second collector that is positioned downstream of the first collector, wherein the second collector is configured to capture particles of a second size smaller than the first size that passed through the first collector.

  • Patent number: 9856160
    Abstract: The systems may be used for treatment of water that contains contaminants. Water containing at least one of a nitrate, percholate, chromate, selenate and a volatile organic chemical is combined with nutrients and then is processed in an anoxic-anaerobic bioreactor. The combined effluent may also be oxygenated by dosing with hydrogen peroxide or liquid oxygen. The combined effluent of the bioreactor is dosed with a particle conditioning agent. The combined effluent treated water of the bioreactor is then filtered in a biofilter to produce a treated effluent stream. The influent water and combined effluent of the anoxic-anaerobic bioreactor may also be dosed with hydrogen peroxide to control biomass content in the system.

  • Patent number: 9737834
    Abstract: A water filter cartridge has an end cap with separate inlet and outlet nozzles connected to the end of a cylindrical tube that extends from the end cap. The nozzles are slanted and laterally offset from the cylindrical tube. A cam surface on the outer side of the nozzles actuates valves in a mating manifold. The passage in the nozzles is conical, expanding toward the nozzle end and opening onto a portion of the nozzle side to form a sharper tip. Expanding ice pushes itself out of the conical passage and facilitates ice removal. The narrow end of the conical passage facilitates breakage and removal of ice from the nozzle.
