  • Patent number: 8434744
    Abstract: A stirring device for activated sludges contained in a basin includes a stirring body having a hyperboloidal wall with a lower circumferential surface, and a funnel-shaped recess underside the hyperboloidal wall; a shaft attached to the stirring body; an air supply line adapted to extend along a bottom of the basin and having a vertical section to supply air into the recess of the stirring body; a disk arranged underside the stirring body and spaced away from the lower circumferential surface to form an annular gap therewith; and shear ribs formed under the lower circumferential surface to extend along the lower circumferential surface and surround the annular gap. The vertical section of the air supply line extends coaxially through the disk in relation to the shaft so that when the stirring body is rotating, the shear ribs distribute air bubbles through the annular gap.

  • Publication number: 20130020400
    Abstract: A rotor for use in a slurry separation flotation cell having a tank within which the rotor is contained. The rotor has a shaft that has a conduit adapted to communicate a fluid, preferably a gas such as air, therethrough. The rotor also has impeller blades extending radially from the shaft and a baffle adjacent the bottom of the impeller blades. The baffle extends from an end of the shaft to at or near an outer edge of the impeller blades, directing the gas to the outer edges of the impeller blades for dispersion into the slurry. The rotor is located adjacent a floor of the tank and, in use, draws slurry downwards into the impeller portion and forces it outwards with the gas being mixed therein.

  • Patent number: 8297599
    Abstract: A submersible aerator has an impeller which includes blades having partition walls which separate liquid passages and air passages and which is accommodated within a guide casing for rotation between a lower surface of an intermediate plate having an air suction opening and an upper surface of a suction cover having a liquid suction opening. The liquid passages and the air passages meet through communication portions at radially outer ends of rear-side blade partition walls. Intermediate blades are provided at radially outer ends of the liquid passages. A conical space is defined between the blade lower end surfaces and the suction cover upper surface such that the space, which is wide at a portion adjacent to the liquid suction opening, becomes narrower toward a radially outward region including guide vane tongues. A plurality of support legs and a plurality of straining projections are integrally formed on the lower surface of a peripheral portion of a bottom wall of the guide casing.

    Abstract: An apparatus for mixing gas and liquid is disclosed. The apparatus can comprise a draft tube having a gas conduit, a liquid inlet and a gas-liquid outlet, an impeller rotatably mounted within the draft tube. The gas can be entrained into the liquid by rotation of an impeller having relatively high angular velocity, which generates relatively low axial velocity of the liquid and relatively low angular velocity of the liquid. Floats may support the impeller and the impeller may have means for maximizing aeration of the liquid.

  • Patent number: 8216456
    Abstract: A water treatment apparatus includes a first fluid channel that can circulate contaminated water in the water body, a first inlet that draws the contaminated water into the first fluid channel, and an outlet that allows the contaminated water to exit the first fluid channel. A second fluid channel installed with a filter therein can filter contaminated water in the water body to produce a filtered water flow. A fluid transport apparatus can draw the contaminated water through the first fluid channel and the second fluid channel. A flow control system allows water to flow in a predetermined angular range while blocking at least a portion of the remaining angular range in at least one of the first inlet and the outlet to achieve mixing coverage with different aspect ratio. The position of the outlet can be adjusted to optimize the flow rate and pattern.
