  • Patent number: 10118115
    Abstract: Some embodiments provide a centripetal air or gas cleaning apparatus for removing particulates from air or gas. The apparatus comprises an inlet, housing, impeller, a clean air outlet, and a particulate outlet. The housing has an inner conical surface. The impeller's rotation creates negative pressure towards the inlet that intakes particulate-pervaded air or gas into the housing. The rotation also induces an accelerating force that throws the particulate-pervaded air or gas against the outer walls of the housing. Here, the particulates separate from the air or gas, penetrate a high-pressure zone, and are ejected through the particulate outlet located in the high-pressure zone. The air or gas, having less inertia, deflects away from the high-pressure zone where it is then subjected to a centripetal force that drives the air or gas towards the center of the housing behind the impeller where it is ejected through the clean air outlet.

  • Publication number: 20150041380
    Abstract: A liquid recovery filter assembly for recovering filtered liquid trapped within a core or downstream side of a filter element. Multiple embodiments each include a recovery port and a recovery filter in fluid communication with the core or downstream side of the filter element. The recovery port is opened following filtration operations to permit and to facilitate filtered liquid to flow from a downstream or outlet port, thus allowing recovery of liquid remaining in the filter core or downstream side following filtering operations. The recovery filter permits the introduction of pressurized gas to force the filtered liquids from the filter assembly without compromising the sterility and/or non-contaminant condition of the liquid.

  • Publication number: 20150031124
    Abstract: The present invention concerns in one aspect a separator for separating the gas and liquid phases of a foam and, in another aspect, a foam reducing apparatus. The separator comprises a first side and a second side and having through-flow means provided therein for permitting a foam or a foam phase to pass from the first side to the second side, the separator further comprising at least one foam contacting surface having a low surface energy, and means for recovering at least one separated foam phase from the foam. The foam reducing apparatus comprises a low surface energy material and means for contacting foam, when said foam is input to the foam reduction apparatus, along a surface of said low surface energy material. The separator and the foam reducing apparatus may be used independently or in combination to good effect to more efficiently disrupt foam to provide separate gas and liquid phases.

  • Patent number: 8940159
    Abstract: The invention includes a method for the optimization of the soluble CO2 concentration in the aeration basin of an activated sludge system, which significantly improves the specific growth rate of the nitrifying bacteria. The result is a reduction in capital and energy costs for municipalities. The rate of nitrification is a product of the nitrifying bacteria biomass concentration and the specific growth rate of the bacteria. In the activated sludge system, the biomass concentration is maintained at high concentrations by reducing the wasting rate. The specific growth rate is a function of the ammonium concentration and the environmental conditions. Here, the inventors show that growth of nitrifying bacteria is inhibited when the soluble CO2 concentration is elevated beyond certain parameters. Elevated soluble CO2 concentration also reduces the pH, which also impacts the rate of growth of nitrifying bacteria.

  • Patent number: 8920658
    Abstract: Methods and apparatus for desolvating flowing liquid streams while retaining temporal resolution of dissolved substrates are disclosed. A novel small-scale self-regulating spray dryer preserves temporal resolution while desolvating a liquid chromatography eluent stream and depositing the solute onto an optical surface for infrared spectrographic analysis. The liquid eluent is pumped through a heated nebulizer to create a high-speed jet of solute containing liquid and solvent vapor. This jet is directed circumferentially inside a hot cylindrical cavity. Centrifugal force causes the larger liquid droplets to travel along the outer diameter of the cavity. The cavity surface is heated to cause the droplets to film boil. Film boiling reduces droplet contact with the cavity surface thereby retaining the solute in the droplets. The solute temperature is limited by controlling the pressure into which the solvent evaporates from the droplets.

    Abstract: A reduced air hydrocyclone unit includes a hydrocyclone having a cylindrical section, a conical base having an underflow outlet formed in its apex, and an overflow outlet on an upper end of the cylindrical section. An underflow basin collects underflow material. Overflow material flows through an overflow line. An exhaust fan of the reduced air hydrocyclone unit withdraws from the overflow material in the overflow line a portion of an amount of air introduced through the apex of the hydrocyclone. A reduced air fluid system includes the reduced air hydrocyclone unit, a fluid tank in fluid communication with the overflow line of the reduced air hydrocyclone unit, and a reduced air hopper for mixing a solid material with a fluid contained in the fluid tank to form a slurry. A liquid barrier inlet of the reduced air hopper creates a liquid barrier to prevent air introduction into the slurry.
