| A plurality of fluent substances are combined in a distributor (11) and caused to flow in a continuous, pressurized stream through a mixing zone (13) wherein the substances are intimately mixed by turbulent dispersion effected by a series of conically shaped surfaces (24,27) and alternate restrictions (25) and expansion chambers (28). While various fluent substances may be advantageously mixed, a typical utility is for effecting a thorough air binding of ink particles to attain efficient foaming in the deinking of reconstituted printed paper slurry. | ||||||

| A compact water treatment plant has at least one vertical stack of dissolved air flotation (DAF) type clarifiers. Raw water is directed first to a single stage clarifier with a shallow tank. Its output is fed to an underlying two stage clarifier, preferably one with tall, mutually isolated cells, inclined baffles over a filtration medium in each cell, a cell-by-cell backwash capability, and an arrangement for isolating the first filtrate from the clarified water. Preferably, there are two such stacks in side-by-side array to provide a peak-load capacity, redundancy, and extreme compactness. Also preferably, clarified water from the single stage clarifier flows to the two stage clarifier via a bioreactor and an associated DAF clarifier. A source of aeration defines an upper, aerobic zone in the reactor where bacteria act on organic contaminants (COD's and BOD's). Strips of a deep pile, woven textile form a biocarrier. The strips oscillate in the tank. A portion of the bioliquor and sludge from the bioreactor-dedicated clarifier recirculate through a lower, anoxic zone of the bioreactor for denitrification. | ||||||

| A two stage raw water clarifier with first stage flotation and second stage filtration divides at least the lower portion of a flotation tank into independent cells. A branched slotted conduit located in a filter medium in each cell collects clarified water. Valves control the flow of clarified water from each branched conduit either to a clarified water ring conduit or to a first filtrate/backwash ring conduit connected to a storage tank. The filter media is preferably a dual media, a layer of anthracite or activated carbon over a layer of sand. High cell walls and inclined baffles in each cell retain the filter media during backwashing. The baffles also slow the flotation process. A decompression valve for pressurized water with dissolved air has a very narrow annular slot in the flow path through the valve to create microscopic air bubbles of optimal size for the flotation. A movable member sets this annular slot at a proper value. A mechanical or pneumatic actuator moves the member periodically to open the slot and flush out trapped particles. | ||||||

| The apparatus includes a powered bowl assembly having a tubular shaft journalled within a base of the apparatus. A pressurized air flow is discharged into slurry in the bowl assembly via a circular array of bubble generators. An impellor discharges the slurry outwardly against an upwardly inclined annular surface of the bowl assembly to cause the slurry to merge upwardly with the streams to promote flotation. Slurry within the bowl assembly forms a vortex with particle flotation forming a froth layer inwardly of a slurry vortex. The froth exits the bowl assembly upwardly past a barrier partially closing the bowl assembly. Heavier gangue particles exit via an outlet about the bowl assembly periphery. A collector shroud is partitioned to receive the froth and the heavier waste material. A modified form of the apparatus includes an independently powered bowl assembly and impellor. | ||||||

| PCT No. PCT/DE79/00090 Sec. 371 Date Apr. 21, 1980 Sec. 102(e) Date Apr. 21, 1980 PCT Filed Aug. 18, 1979 PCT Pub. No. WO80/00423 PCT Pub. Date Mar. 20, 1980. A pulp suspension of waste paper which is laden with air bubbles is introduced into a flotation cell. Fine air bubbles rise through the pulp suspension toward the top. Printing ink and other impurities are deposited on the bubbles which form a foam layer on the surface of the pulp suspension. The foam which is laden with impurities is drawn off from the surface. The fibers which have been subjected to preliminary purification in this manner sink downwardly. For reducing the number of cells connected in series to fewer than a third, while obtaining the same degree of whiteness, the fibers which were subjected to preliminary purification are drawn off and are once again supplied to the flotation cell in the form of an air-laden pulp suspension. Alternatively, instead of the air-laden pulp suspension, a water-air suspension can be injected. The air bubbles which are thus introduced once again rise toward the top and traverse the sinking fibers in a counterflow. As a result, an intensive air-pulp contact is created. | ||||||

| A filter device suitable for use in cleaning dampening water used in an offset press. The filter device has a tank in which are defined three sections: a stirring tank section, a floating tank section and a discharging tank section. The floating tank section and the discharging tank section are communicated with each other through a passage at their lower regions. The passage is adapted to be selectively closed by a shut-off device which is operated periodically under the control of a timer. A floating contaminant removing opening es positioned above the water level in the floating tank section. The contaminated water is poured into the stirring tank section through a bubbling means so that contaminants are adsorbed by the bubbles. The bubbles adsorbing the contaminants are allowed to float in the upper region of water in the floating tank section. When the passage is shut off by the shut-off device, the water level in the floating tank section is raised so that the contaminants are removed together with the bubbles through the floating matter removing opening. On the other hand, the cleaned water free of contaminants flows into the discharging tank section through the passage and discharged outside the tank so as to be recirculated to the offset through a filter. | ||||||

| Device for froth flotation of suspensions, especially of fibre suspension, in which the suspension, laden with air by means of an injector which has an essentially tubular mixing chamber, is supplied from the mixing chamber to the flotation vessel, characterised in that the outlet orifice(s) of the tubular mixing chamber are directed towards the bottom of the flotation vessel and are located at least approximately in the central axis and near the bottom of the flotation vessel, and in that the latter has an annular discharge cross-section for the discharge of the suspension from the flotation vessel, which is arranged so as to encompass the latter on its outside, seen radially. Owing to the flow conditions in the, if possible, at least approximately circular-cylindrical flotation cell, which result from this arrangement, strong infiltration of the suspension with very fine air bubbles is achieved with little energy input. The main field of application is the paper industry. | ||||||

| A vertical column (1), assembled from one or more tubular parts (2), is charged with the liquid to be treated by gases and also with the gases under pressure. Each tubular part (2) of the column (1) contains a hollow spherical funnel (3, 3') which has an electrically conducting surface and an enlarged, rough head area. The sphere (3a) has an inlet opening (4) for the liquid and the gases, which leads into the interior of the sphere (3a). It is positioned approximately tangentially and in a transverse direction relative to the longitudinal axis of the spherical funnel (3, 3'). Its orientation confers the desired flow direction on the liquid entering the sphere (3a). The liquid is split electrolytically-physically or only physically in column (1) and then set in centripetal whirling motion. In this way the liquid is saturated in column (1) with gases to a very high degree, and such saturation to a very high degree persists for several hours. <IMAGE> | ||||||
