  • Patent number: 10099942
    Abstract: Systems and methods of eliminate filter air locks by maintaining a constant water table at the water head layer of the filter. The constant water table eliminates air locks in the filter as the filter drains. Water flows from the water head layer through a filtration medium in a filter cartridge, and the filtered water is output from a water outlet at the top of the cartridge. For a water table retention filter, where the water (or other liquid) being filtered, is re-directed to the top of the filter to the water head layer to avoid drawing air into the filter. Unfiltered water drains down the center of the filter to the water head layer and then flows up through the filter and is directed out near or at the top of the filter.

  • Patent number: 9993745
    Abstract: Wastesolution treatment systems and methods are provided which may remove particulates and hydrocarbons from wastesolution. Embodiments may be used to treat scrubber wastesolution from exhaust gas cleaning (“EGC”) systems. Some embodiments may be used with terrestrial EGC systems and others may be used for maritime ship EGC systems. Certain embodiments remove free phase oil and particulates from the wastesolution. Some embodiments may utilize a fixed film biogenerator cultured with hydrocarbon degrading microorganisms to reduce the concentration of oils in the water. Certain embodiments may utilize a biofilter with granulated activated carbon (“GAC”) to adsorb contaminants in the water. Other embodiments may utilize GAC cultured with hydrocarbon degrading microorganisms to reduce oil concentration in the water. The wastesolution may be recirculated through the system until the measured contaminant concentration drops below a threshold value.

  • Patent number: 9993096
    Abstract: The present invention relates generally to a treatment for hiccups. A device for treating hiccups utilizes a replaceable filter through which liquid must be manually drawn by a vacuum force created with the user's mouth and through which liquid will not naturally flow due to the effects of gravity. The user's draws the liquid through the filter in this manner and swallows, which eliminates the user's hiccups.

  • Patent number: 9969624
    Abstract: A simple to operate personal water purification device using membrane type filtration with almost constant pressure exerted to the membrane filter during the operation. The water inlet is connected to the high pressure chamber via a non-return valve. The water from the chamber is injected via the piston into the already pressurized circuit which maintenance filter working pressure. A pressurized circuit is formed in the concentrate cylinder and the filtration unit. The fluid circulation within the pressurized circuit is enabled via motion of a circulation piston. The permeate outlet produces potable water while the remaining concentrate is returned to the return chamber. The circulation piston and high pressure piston are connected via piston coupling and operated, preferably, by hand activating reciprocal motion of the piston rod. The membrane type filtration can be a ultra-filtration membrane, a nano-filtration membrane or a reverse osmosis membrane.

  • Patent number: 9943787
    Abstract: An oil filter assembly is disclosed for a machine, such as an internal combustion engine, that has an oil output port and an oil input port. A mounting plate may be fixed with an outer enclosure and may be adapted for securing to the machine. The mounting plate may be further adapted to conduct oil from the machine into a peripheral portion of the outer enclosure, and then returning oil from a central portion of the outer enclosure back to the machine. Oil may pass from the peripheral portion to the central portion through a primary filter having a first porosity. A pressure-actuated valve may be fixed fluidly between the peripheral portion and central portion of the outer enclosure. Oil may pass through the pressure-actuated valve only when an oil pressure differential between the peripheral portion and the central portion of the outer enclosure exceeds a predetermined threshold pressure.
