  • Patent number: 11103816
    Abstract: A potable water filter for an aircraft galley plumbing system is disclosed. In embodiments, the filter includes a body attachable to a mount via a central threaded attachment stud. The stud is surrounded by a filter mount chamber and encloses a central flow channel allowing outflow from the filter body to an outlet port. Potable water enters the mount through an inlet port including a barrel valve that opens to allow water flow when the filter body is screwed onto the stud, and seals off the filter mount chamber when the filter body is absent. The outlet port includes a check valve to prevent backflow into the filter. The filter body houses a solid block of sintered carbon with a hollow core. Water enters the filter chamber and flows around and through the carbon filter before flowing down to the outlet port. The filter body self-vents at its top.

  • Patent number: 8974677
    Abstract: Fluid processing apparatuses and systems are disclosed. In some embodiments the fluid processing apparatuses include a movable enclosure, a plurality of filter housings disposed substantially within the movable enclosure, and a stand disposed within the enclosure. The filter housings are in fluid communication with one another. Each filter housing defines an elongate path and is configured to support a respective filter along the elongate flow path to filter a substantially continuous flow of fluid. The stand supports each filter housing such that the elongate flow path of each filter housing is substantially parallel to a vertical axis, wherein each filter housing is independently rotatable, relative to the stand.

  • Patent number: 8968568
    Abstract: A water or liquid substance filtration device is disclosed which removes microorganisms and organic contamination and sterilizes the containers and water lines after the unit. The unit is portable, or can be mounted stationary. The unit has a five-stage filtration and sterilization system controlled by an independent onboard computer system that can link to a central computer system to keep track of all independent units. The unit will physically filter out of the water contaminants that can be reused, destroyed, or flushed down a safe drain. It can also be modified to filter for a certain size of particulate, making recovery of certain substances possible. The unit has a self-diagnostic system that can determine if the unit is operating properly and can shut down a part thereof if one of the capillary units fails. The unit uses ozone to disinfect containers and water lines.

  • Publication number: 20150048033
    Abstract: There is disclosed a liquid filter system that includes a liquid filter apparatus configured to self-clean without removal of the filter apparatus from the filter system. The filter apparatus uses both a filter media for filtering solids as well as a spin motion imparted to fluid being filtered so that centrifugal force can remove solids from the liquid being filtered. The liquid filter system also includes a gas pulse nozzle in fluid communication with the liquid filter apparatus and is configured to flow gas into the filter media to expel water and debris trapped in the filter media without removing the filter media from the filter system.

  • Patent number: 8951418
    Abstract: A method of operating hydrocyclone comprising a separation chamber which in use is arranged to generate an internal air core for affecting a material separation process, comprises measuring both a vibrational parameter of the separation chamber and a stability parameter of the internal air core during operation of the hydrocyclone. The measurements are compared against predefined corresponding parameters which are indicative of a stable operation of the hydrocyclone and an operational parameter of the hydrocyclone is adjusted dependent on the comparison.

  • Publication number: 20140346120
    Abstract: Disclosed is an operating logic of an organic material thermal hydrolysis system. One or at least two reactors are used and controlled according to a control program based on an operating logic stored in a PLC or a micro-computer to improve digestion efficiency and to minimize an amount of a sludge dehydrated cake in a dehydration process after the digestion process has been performed. Waste heat generated from a reactor is used to preheat the conditioning tank to save operating energy, and continuously generated waste heat is continuously used.

  • Publication number: 20140342397
    Abstract: The invention relates to a device and a method for detecting particles, in particular parasites, in drinking water adapted to on-line application. In particular, the invention b) relates to a method for detecting parasites in water, said method comprising: Passing at least a part of the water through a filter; Applying indirect sonication with ultrasound to said filter to release parasites which have been collected in said filter without disrupting said parasites; Collecting parasites for detection; and Detecting the collected parasites. This serves to collect parasites in the filter and/or increase the concentration of parasites before the filter and/or disrupt aggregates without disrupting the parasites per se. The invention further relates to a concentration device for filter filtration concentration of particles from a volume of a fluid. The concentration device comprises an ultrasonic transducer that is configured to clean the filter.
