| A gas flotation separator for use in horizontal tanks, such as those used for oil storage on board Floating Production Storage and Off-loading (FPSQ) vessels, includes dividing the tank into a plurality of chambers operating in series. Prior to entering each chamber, the contaminated aqueous phase is mixed with a stream containing gas bubbles to aid in flocculation and flotation of the immiscible phase contaminant. The gas bubble recycle stream can be generated by injecting a controlled rate of a pressurized gas into a liquid stream of the clean produced water in a process external to the tank or by induction of a gas phase internal to the tank. The mixture flows into the first chamber and impinges on an angled inlet water weir. A portion of the immiscible phase and the gas phase rises to the top of the chamber while the remaining immiscible contaminants flow downward with the aqueous phase to the bottom of the chamber. The aqueous phase makes a 180°turn upward by entering a plurality of parallel flow conduits formed into the wall of the baffle that separates the each series chamber. In each parallel duct a second gas bubble stream is injected to further aid in flocculation and flotation of the immiscible contaminants. The aqueous phase remixes at the top of the second chamber where it impinges on a second angled weir. This process is repeated in each series chamber until the last chamber where the cleaned water is pumped out of the chamber via a liquid pump. Varying the rate of water removal there from controls the water level in last chamber. The flocculated and floating oil contaminant can be removed by either 1) periodic skimming into an over-flow weir by raising the water level in the chamber, or 2) a continuously rotating paddle or brush object that lifts or carries the floating oil layer away from the water surface and transfers it to a collector system. | ||||||

| The de-inking procedure consists of circulating the pulp in a flotation cell comprising a chamber (2) with a vertical axis in which the pulp can move downwards from top to bottom, passing through a series of stages (E1...En), in each of which bubbles (13) introduced in the lower part of the chamber pass through it. The bubbles reach the top of the chamber in the form of a foam (5) carrying particles of non-soluble materials, the foam being removed at the top while the de-inked pulp is drawn off at the bottom. In each of the aforementioned stages the rising bubbles follow the under-surface of a spiral guide (12) to reach the passages taking them to the higher levels. In addition, the speed of the pulp is accelerated at the passage entrances by a progressive reduction in the passages' cross-section to draw the bubbles through and mix them with the pulp. | ||||||

| 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. | ||||||

| The DC supply to the electrodes of the reactor, is pushed at up to 800 Hz. At the same time, the inlet flow is accelerated in a short pulse, and constrained to flow with elevated velocity over the electrodes. The electrical conductivity of the flow is measured between the electrode cross sections. From this result, the applied DC current is controlled to maintain optimal current density corresponding to the complete, original electrode cross section. Equipment to carry out the above procedure is also claimed. | ||||||

| 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. | ||||||

| 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. | ||||||

| 1,241,051. Flotation apparatus. BERGWERKSVERBAND G.m.b.H. 2 Aug., 1968 [5 Aug., 1967], No. 37079/68. Heading B2H. Apparatus for effecting the classification of particles by flotation comprises a cell a containing a series of zig-zag guide walls 21 to form a number of zig-zag ducts, diffusers 17 arranged below the cell a to conduct a suspension of solid concentrated particles in a finely dispersed mixture of air bubbles to the ducts and to reduce the entry speed of the suspension into the ducts and irregularly arcuate guide wall portions 45 arranged to produce eddy zones at the bends in the zig-zag ducts. As shown in Fig. 1b an aqueous suspension of a material passes from a rod mill to a stirring mixer where reagents are added and then to a pre-mixing chamber 4 which is provided with internal fittings 5 which distribute air into the suspension, a supply duct 6 opening into the chamber 4 and serving for the introduction of air and a mist of a foaming reagent formed by an atomising device 7. The suspension passes to a stirring device which includes an annular space 10 from which the suspension passes through a number of outlet openings 11. Coarse particles coming against the wall of the space 10 are passed by centrifugal force through ducts 12 for repeated treatment. The suspension passes through flexible ducts 16 to the diffusers 17, oversize particles being separated and fed back through hoses 18 into a dock 19 for further treatment. Each of the diffusers opens into the zig-zag ducts the zigzag walls 21 ending in the upper part of cell a at different levels so that the suspension is directed at right angles and moves over a sedimentation device 22 the tapering outlet ducts of which are connected by means of flexible pipes to an overflow 25 the height of which can be adjusted by a handwheel 21. Above the foam bed runs an endless band provided with blades 30 which remove the foam to a gutter 29. | ||||||
