| Disclosed is a clarifier for use in treating a liquid containing non-soluble particles in suspension in order to separate these particles from the liquid. It comprises a tank, a liquid supply duct opening into the bottom portion of the tank and an injector for injecting a gas under pressure into at least part of liquid supplied to the supply duct in order to saturate this liquid with said gas and thus to generate gas bubbles as the saturated liquid is subject to depressurization within the tank. The gas bubbles that are so-generated adhere to the particles in suspension in the liquid and lift them up to form a floating layer of sludge in the top portion of the tank. A scraper is provided in the top portion of the tank for skimming off the layer of sludge while it is formed. A plurality of plates extend at an angle within the tank above the supply duct. These plates define a set of upwardly inclined channels each having an upper end that is opened and through which the liquid fed into the tank may enter the channel. A liquid outlet mounted within the lower end of each channel to collect and remove from the tank the liquid that has been treated within the same. Thanks to its shape and structure, this clarifier occupies a surface area on the ground that is 50% or less smaller than any known clarifier of the same capacity. Its structure also permits to maintain much more microbubbles of requested size for a same amount of injected air in order to increase the probability of contact between the particles and the air bubbles. | ||||||

| A dissolved air flotation (DAF) system and method for gas-liquid contacting operations. A mixture of untreated liquid and liquid saturated with dissolved air is passed through a series of upward deflecting screens placed across the flowpath in a rectangular tank. Microbubbles of air released from the mixture produce a buoyant force which carries contacted particles to the surface. Floated particles released from the microbubbles form a sludge which is supported above the surface of the mixture by a layer of air derived from the microbubbles. A top layer of the sludge is skimmed off according to a predetermined residence time of sludge at the surface. Liquid containing dissolved air is also introduced downstream of each deflecting screen to enhance flotation and clarification. | ||||||

| An aeration/flotation reactor, of particular usefulness in the treatment of biomass-containing liquids, comprises a foam tube which terminates at the top in a collecting vessel and overlaps, or is inverted over, an inner rising tube which is preferably coaxial. The latter tube delimits an inlet chamber positioned, at the bottom of the foam tube, to receive liquid and finely divided gas bubbles. The lower end of the foam tube is enlarged, preferably into a funnel-shape, and runs into the lower region of an outer tube, the upper end of which is connected, via a return tube, to the inlet chamber below the axial rising tube. The outer tube, which is open at the top, is provided with a T-shaped liquid outlet having a dip connector, which extends below the liquid level, and with an outlet level immediately above the junction of the return tube, The upper end of the foam tube can be extended telescopically, thus permitting adaptation of the device to liquid/gas systems characterized by different foam properties. | ||||||

| Components, usually but not exclusively gaseous components, are removed in a liquid medium from gas streams and chemically converted into an insoluble phase or physically removed. Specifically, hydrogen sulfide may be removed from gas streams by oxidation in aqueous chelated transition metal solution in a modified agitated flotation cell. A gas-liquid contact apparatus, generally a combined chemical reactor and solid product separation device, comprising such modified agitated flotation cell also is described. In order to effect efficient mass transfer and rapid reaction, gas bubbles containing hydrogen sulfide and oxygen are formed by rotating an impeller at a blade tip velocity of at least about 350 in/sec. to achieve the required shear. To assist in the reaction, a surrounding shroud has a plurality of openings, generally of aspect ratio of approximately 1, of equal diameter and arranged in uniform pattern, such as to provide a gas flow therethrough less than about 0.02 lb/min/opening in the shroud. In general, the gas velocity index is at least about 18 per second per opening, preferably at least about 24 per second per opening. Each of the openings has an area corresponding to an equivalent diameter less than about one inch. | ||||||
