摘要： A device for co-mingling fluids from separate sources comprises a jet pump having high and low pressure fluid inlets, and a main outlet for discharging a mixture of the two fluids. A phase separator, receiving fluid from another source of fluid, has a fluid-rich outlet connected to the high pressure inlet of the jet pump, and a gas-rich outlet connected to the main outlet of the jet pump. Fluids from the gas-rich outlet of the separator are mixed with fluids discharged by the jet pump.

摘要： A device for mixing two fluids, of which at least one is a liquid, which has a tubular vessel open on both axial ends for receiving the fluids, at least two nozzles which are separated from one another in space for supplying the fluids and a guide device one end of which communicates with the nozzles. At a location approximately in the middle of the guide device, it discharges into the vessel, the vessel surrounding at this point an impact zone in which fluid streams emerging from the guide device impact each other. The guide device is joined securely to the vessel and, one of the walls of the guide device defining a closed passage is the wall of the vessel.

摘要： A sewage purification method which includes a first step in which at least two kinds of flocculants are introduced in sewage for stirring and mixing therewith so as to float and settle inorganic and organic materials. The first step is sequentially repeated more than one time. Next, at least three kinds of flocculants are introduced into the supernatant obtained in the first step for stirring and mixing therewith so as to further float and settle remaining inorganic and organic materials. At least one of the first and second steps is sequentially repeated more than one time. In the above way, middle water, drinking water and super-pure water can be obtained from sewage. Purification of exhaust gas is also possible by introducing such exhaust gas in one of the above steps.

摘要： Apparatus and methods for mixing a liquid and a flowable treating agent wherein liquid from a body thereof is pumped through a conduit submerged in the body of liquid and having a constricting nozzle therein which produces low pressure zone downstream of the nozzle. A draft tube communicates with the conduit in the vicinity of the low pressure zone and directs the flowable treating agent into the conduit by suction for mixing with the liquid. The nozzle outlet has a plurality of radially spaced slots separated by solid land portions which together interact with the fluid discharged from the nozzle to produce multiple, axially spaced venae contractae in the fluid downstream of the nozzle to effect mixing of the liquid and treating agent.

摘要： A process and system for enhancing the oxygen uptake by a liquid being aerated in a basin or tank with the aid of an aerator which can only aerate the liquid over a cross-sectional zone smaller than the total floor surface of the basin or tank. To achieve the enhancement, there is provided vertically above the aerator but at the surface of the body of liquid an enclosure which is open at its top and bottom and has a cross-sectional size sufficient to surround approximately the entire region where the rising directly aerated quantity of liquid reaches the surface of the body liquid. The enclosure, which when installed has its top edge arranged above and its bottom edge below the surface of the body of liquid, is constructed and arranged to either entirely or partly inhibit flow of the upwardly displaced aerated liquid laterally outwardly from the region of its arrival at the surface of the body of liquid, thereby to control the "airlift effect" and the resultant liquid circulation which tends to reduce oxygen uptake.

摘要： An aeration and mixing apparatus for use in a wastewater treatment facility is mounted on a float and includes an axial-flow mixer having a stem that extends through a flow channel in the float, a diffuser cone slidingly mounted on the mixer stem and a diffuser hood fixedly attached to the diffuser cone and located below the float. A diffuser-drive mechanism mounted on the float transfers the diffuser cone and attached diffuser hood between a first, aeration position and a second, anoxic-mixing position. In the first position, the cone is spaced above the channel of the float and the diffuser hood abuts a bottom surface of the float with wastewater being propelled by the mixer upwardly through the hood and flow channel onto the diffuser cone where it is dispersed outwardly in the air above the float. In the second position, the cone is seated on the float in the channel, blocking flow of fluid through the flow channel, and the diffuser hood is spaced from the bottom of the float with the mixer propelling water downwardly through the hood.

摘要： A centrifugal oxygenator pump includes a bottom inlet into an impeller chamber, the bottom inlet having a venturi gas inlet for mixing gas with the in flowing liquid. The impeller chamber is of a frusto-conical shape within which is rotatably mounted a similarly shaped mismatched impeller, the impeller driving the liquid and gas mixture toward a toroidal outlet chamber and through an outlet to an outlet nozzle. The motor drives the impeller to attain a high specific speed so that an increased capacity and larger size oxygenator is provided with maximum efficiency and effectiveness.

摘要： Improved methods apparatus are provided for introducing and entraining air into a waste liquid, thereby increasing the quantity of dissolved oxygen in the liquid to enhance the aerobic treatment process. A power driven propeller is preferably positioned at the discharge end of conical-shaped transition housing, and draws in air while waste water is controllably introduced to the transition housing from below the surface of the water. The housing upstream from the propeller is primarily an air chamber with incoming streams of water, while the housing downstream from the propeller is filled with waste water having minute entrained air bubbles. The water and entrained air are thus discharged downwardly, and the axis of the equipment preferably inclined to increase circulation in the waste water pond or tank. The techniques of the present invention have relatively low power requirements while substantially increasing gas concentration in the liquid.
