摘要： A bubble injection system for forming and distributing micron size gas bubbles in a body of liquid at the point of use of the bubble distribution comprising an axially extending inner fluid conduit forming an axially extending liquid flow channel and a concentric outer fluid conduit extending axially along the inner conduit and spaced therefrom. An outer gas channel is defined by the conduits and includes a plurality of porous outlets extending thereacross from the inner conduit to the outer conduit. The porous outlets terminate in outlet jet ports spaced along the outer conduit whereby gas flowing through the gas channel will penetrate the porous tubular outlets to form gas bubbles and liquid floring through the liquid conduit and outlets will sweep the gas bubbles from the surface of the outlets toward and out of said jet ports for immediate dispersion of the body of liquid.

摘要： A static oxygenator for oxygenating a liquid, particularly a suspension culture of animal cells in a liquid culture medium, comprised of a bottom gassing portion comprised of generally concentric vertically oriented hollow cylinders of porous gas-permeable, liquid-impermeable material, and an upper degassing section comprised of vertical extensions of the concentric cylinders such that at least one liquid overflow weir is provided at the juncture between the bottom and upper sections. Gas directed into the bottom of the annular space between the concentric cylinders rises therein and, across the porous material, oxygenates liquid in contact therewith or in proximity thereto up to the point where the liquid overflows the weir, and the gas then continues up the annular space in the vertical extensions for degassing through the porous material above the liquid level.

摘要： A froth flotation system for separating a mineral fraction from an aqueous pulp containing a mixture of mineral and gangue particles. The aqueous pulp is supplied to a pulp-filled vessel (or column) wherein a froth is formed on the surface of the pulp and collected in a launder. Gas bubbles are introduced into the pulp in the vessel by two different means to generate the froth. In accordance with one means, water is aspirated into a stream of pressurized gas (air) to form a stream of aerated water which is injected into the lower portion of the pulp-filled vessel. In accordance, the other means, a second stream of pressurized gas (air), is sparged through a porous wall of one or more micro-diffusers located within the vessel. The dual means for generating bubbles produces a significantly higher level of mineral separation than can be achieved from either means separately.

摘要： A fluid supply pipe has uniformly spaced diffuser location holes arranged in a line along its length at each of which a saddle is secured to the pipe which includes changeable means for controlling the desired flowrate of fluid from the pipe to a diffuser. The saddle has a threaded connection with the diffuser so that the diffuser can be readily screwed onto or unscrewed from the saddle by hand. The plenum below the diffuser element has a self-draining feature.

摘要： A plurality of aerators are arranged in a preselected pattern on the floor of a basin or lagoon containing waste water. Compressed air is supplied to the aerators by aeration pipes anchored by hanger brackets to the floor of the basin. Each aerator has a porous diffuser plate through which the air is passed and released into the waste water in the form of ultra fine air bubbles less than 60 microns in diameter. The air bubbles are generated in an intense manner with a high rate of air flow to increase the mixing action and liquid circulation pattern, and to create turbulent boils at the surface which provide surface aeration from atmospheric air and re-entrainment of air from eddy current circulation.
