  • Patent number: 9101884
    Abstract: Embodiments provide methods and apparatuses for filtering a fluid through a porous membrane, and more particularly, it provides filtration methods and apparatuses for tangential-flow filtration using Vibration Induced Dynamics (VID) with a spiral-wound membrane filter element. Embodiments provided herein induce vibration via rotation of an unbalanced inner tube within a central filtrate drain tube, via axial deformation of a substantially circular-cylindrical outer shell, or a combination thereof. Also disclosed herein are friction-reducing separator fabrics for interleaving with the membrane of a spiral-wound filter element.

  • Patent number: 9096445
    Abstract: A water purification apparatus comprising at least: (a) one or more water purification components in a housing; and (b) a handset integral with the housing, and moveable between a supported position on the housing and a suspended position beyond the housing, the handset including one or more water purification controls thereon. In this way, at least one control of the purification of the water in the housing is operative on the handset, which handset is useable either in its supported position on the housing or in its suspended position beyond the housing, whichever is most convenient to the user. More convenience is therefore provided to a user by the present invention compared with conventional purification apparatus.

  • Patent number: 9074355
    Abstract: A domestic water recycling system using a combination of an optical detector to detect certain smaller sized (non-filtered) contaminants and a filter to remove larger sized (filtered) contaminants provides an efficient wastewater recycling system. Optical detection of contaminants determines whether water is discharged or filtered and recycled. The optical detection system can use several discrete optical wavelengths that are passed through the fluid, and can determine a relative presence of the contaminants based on the resulting wavelength response. A recycling shower using optical detection, an electronically actuated directional device and pump and a controller allows for automatic recycling or discharging of water without requiring user input. The system may include a turbulence reduction baffle in a collection chamber, and a disinfection unit for the recycled water.

  • Patent number: 9072992
    Abstract: A modification of a fuel filter for use with an internal combustion engine is described. The modification provides a switch element that, in conjunction with the water level sensor conventionally provided in the filter, enables detection of the presence or absence of a filter insert or whether an improper insert has been installed in the filter housing. When the filter insert is inserted or removed, the switch element makes or breaks an electrical circuit that is part of the water level sensor. The control unit is thus able to detect switch states of three different variables in the filter: the water level is/is not too high; the filter insert is/is not installed; or the correct filter is/is not installed. The control unit accordingly allows or prevents operation of the motor, depending on the detected switch state.

  • Patent number: 9004292
    Abstract: Embodiments of the present disclosure could generally provide a relatively easily squeezable beverage bottle that allows control of the flow rate of the liquid being dispensed to the user. The bottle could provide sufficient radial rigidity—or resistance to squeezing—to return to its original shape (or “bounce back”) at a suitable rate without experiencing permanent deformation or denting and to withstand the rigors of filling, shipping, transporting, dispensing, etc. The present disclosure generally provides a beverage bottle filtering system that provides adequate filtering of water taken from the bottle at a suitable rate. In one embodiment, the present disclosure could include a support system to adequately secure the filter media within a filter housing while ensuring a sufficient compression fit and seal of filter media within filter system to eliminate “bypass flow” (i.e., water that might leak past filter system) and prevent consumption of unfiltered water.
