摘要： A system and method for oxygenating an aerobic sludge digester is provided. The disclosed embodiments include an aerobic sludge digester tank or vessel having a mechanically agitated contactor disposed therein, an oxygen injection subsystem adapted to inject oxygen into the digester tank proximate the mechanically agitated contactor. The embodiments of the mechanically agitated contactor include an agitator or impeller disposed within the draft tube which makes the draft tube the primary site for the gas-liquid mixing. In particular, the agitator or impeller is adapted to create gas bubbles having an average diameter between about 0.3 mm and 3.0 mm which are then dispersed into the aerobic digester. The mass transfer efficiency associated with the present system and method is enhanced from the combined effect of oxygen dissolution into the sludge and greater bubble residence time.

摘要： This circulation device is equipped with a water impeller that is larger than and tightly fitted over the top of the draft tube through which the water from the pond or reservoir is drawn. By placing the impeller above and out of the draft tube it enables the present invention to lift water up through the draft tube and imparts a centrifugal force on the water above the impeller which aids in moving the water radially outward from the impeller. The water is then directed outwardly over a large diffuser plate that is centrally located within the invention. The outer edge of the diffuser plate is equipped with a laminar flow diffuser lip which is specifically designed to inhibit the passage of water from the diffuser plate to the open water as little as possible. This design feature ensures that most of the energy imparted to the water by the impeller is retained once it leaves the diffuser plate, making the invention as a whole operate more efficiently.

摘要： Apparatus for mixing air with liquid (aerator or oxygenator) comprises a motor or other power drive generally mounted in vertical position on a float or a fixed structure, the motor having a shaft extending downwards through an opening in the center area of the float or fixed structure and bearing on its lower part a propeller located in a cylindrical volute section just underneath the waterlevel. When the apparatus is operating, the waste-water is sucked by means of the propeller from the bottom of the body of liquid on which the apparatus is floating and pushed upwards in order to be diffused by means of a rotating diffusion head in the shape of a paddle-wheel. This feature increases efficiency of the installation, allowing the velocity of the fluid leaving the propeller to be kept as low as possible and the dimensions of intake volute and propeller to be increased.

摘要： The invention provides an aerator device for dispensing liquid in a gas phase by producing an upwardly-directed spray of the liquid from a tank. The device, which is intended to be submerged in a tank, comprises a motor-pump unit in the vicinity of the tank floor and a primary flared tube and a secondary flared tube coaxial therewith. The secondary flared tube is connected to a delivery nozzle by an intermediate duct, and the delivery nozzle is surmounted by an adjustable needle. The buoyancy of the whole assembly is ensured by a set of variably ballasted buoys which pivot at the end of support arms, and by an upper buoy concentric with the nozzle.
