| 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. | ||||||

| Hydrogen sulfide or other gaseous component is removed from a gas stream containing the same by distribution of the gas stream in the form of fine bubbles by a rotary impeller and stationary shroud arrangement at a submerged location in an aqueous iron or other transition metal chelate solution, or other suitable catalyst, contained in an enclosed reaction vessel. Sulfur particles, or other insoluble phase product, of narrow particle size range formed in the reaction are floated off from the iron chelate solution. An oxygen-containing gas stream also is distributed in the form of fine bubbles by a separate rotary impeller and stationary shroud arrangement at a separate submerged location in the iron chelate solution. The second submerged location is separated from the first by a bafle extending downwardly in the reaction vessel from a top closure towards a bottom closure. | ||||||

| A process for the purification of soil contaminated with organic material is provided. The preferred process generally involves superposed attrition (35) and classification (40) processes, which lead to removal and concentration of highly comtaminated fractions. The process may also include a step of flotation (60) whereby hydrophobic materials in the soil are released to an interface with air bubbles, and are floated to the top of a flotation cell. In preferred processes according to the present invention, soil to be treated is extracted from a contaminated site, and is broken into relatively small particles. These particles are preferably treated in attrition and classification steps, to remove fine, slow settling, contaminated materials such as wood and fine soil materials. The resulting isolated coarser materials are then treated by flotation for a final polishing step. The process is particularly well adapted for use in treating soil contaminated with oil and grease materials containing PCP therein, from wood treatment plants or the like. | ||||||

| PURPOSE: To perform stable operation of a flotation system while suppressing the disturbance of the operation state with foam by measuring the amount of foam defined by the height of foam in a foam-collecting groove of a flotation cell, relative air content, content of precipitated slurry, etc., with a sensor and controlling a specific parameter by the measured data. CONSTITUTION: The generation of foam in a flotation cell or a flotation apparatus is controlled by introducing a paper fiber suspension from a supplying line 2 into a cell 1, introducing air into the supplying line 2 through a control valve 4 and a metering line 3, mixing the air into the suspension by the sucking action and turbulent action to generate fine foam and clean the suspension, measuring the quantity of the foam as the height of foam collected in the foam collection groove 5, relative air content or content of precipitated slurry with a corresponding sensor 7 attached to the foam collection groove 5 and controlling a parameter of the material or process relating to the flotation apparatus affected by the quantity of foam by a controller 8 based on the measured data.

| A defrothing apparatus whose inlet opening of the foamed liquid contained in a foam duct of a primary flotation apparatus is provided in the bottom of the foam duct. Starting from the lower area of the defrothing apparatus, a rotary flow (potential vortex) is generated in the apparatus by a recirculated lqiuid quantity from a secondary flotation apparatus. In the core of the rotary flow the gas quantity (air) is collected and removed through a removal pipe. Consequently, the foamed liquid from the foam duct of the primary flotation stage which is pumped to the secondary flotation stage contains small shares of gas relative to the total quantity of liquid, thereby allowing the pump to be optimally sized of efficiency and better control of the system. | ||||||

| Process and device for the flotation of fibre suspensions in one or more flotation cells. The suspension quantity to be purified is fed without aeration to the respective flotation cell. The fresh air injected in the bottom part by means of at least one aeration apparatus is utilized for the repeated washing out of the rotating pulp suspension, the amount of circulation required for aeration being greater than the new amount of suspension to be cleaned. The washing out in the individual washing stages proceeds in the co-current or counter-current process. In the last stage, the washing out is carried out using fresh air. After each washing stage, a complete degassing of the pulp suspension is carried out. In the case of more than twofold washing out, the circulation is carried out in the central washing out stages by means of weight difference between the aerated and degassed pulp suspension. In the case of plants having more than one flotation cell, the transport of the suspension from one cell to another cell proceeds by free fall. The flotation froth is conducted away at the surface of the cell. | ||||||

| An improved method and apparatus for froth flotation separation of the components of a slurry, having particular utility for the beneficiation of coal by the flotation separation of coal particles from impurities associated therewith, such as ash and sulfur. In this arrangement, a forward product stream is formed in which a mixture of the particulate matter slurry and the chemical reagents is sprayed through a nozzle at a first relatively low pressure onto the surface of water in a forward stream flotation tank to create a floating froth phase containing therein a first quantity of the particulate matter. The remainder of the particulate matter slurry separates from the froth phase by sinking in the water, and the froth phase is separated as a first product. The remainder of the particulate matter slurry is then directed to a scavenger product stream in which the separated slurry is sprayed through a second nozzle at a second higher pressure onto the surface of water in a second scavenger stream flotation tank to create a floating froth phase containing therein a second quantity of the particulate matter. The second froth phase is then separated as a second product. The amounts of the products recovered in the first and second product streams are substantially independently adjustable by controlling the first and second spraying pressures. | ||||||

| A floatation tower for paper recovery has a set of cells one above the other, holding the fibrous paper paste, and into which water and compressed air are injected so that the impurities mix. with the bubbles to form a foam which can be removed separately. Water is admitted as a thin layer at the same time as the air to mix. with the liquid paste as it is circulated in a thin layer in a mixing chamber, passing it through and along the flow, controlling the thickness of the layer. Air is then admitted to skin off the foam and drive it into a collector vessel below, for recycling. By a similar process for each cell, ink, kaolin and fibres can be removed separately. The mixing chamber is conical, with a tangential lop entry. | ||||||

| The injector apparatus is of the kind having a constriction which lies, in the flow direction, immediately before a following adjoining mixing section, in which fibrous stock suspension is mixed with air for the purpose of subjecting the suspension to flotation in a flotation tank. The mixing pipe in which the mixing section is disposed has a radial diffusor at its outlet end, and, for a greater flow rate of air, additional air intake bores are disposed therein a short distance in the flow direction after the constriction. A favorable arrangement is achieved if the injector apparatus with the mixing pipe is arranged perpendicularly in a flotation tank, which may have the form of a reclining cylinder. In this case, the froth, like the cleaned suspension, is drawn off on one long side, i.e., a side which extends parallel to the cylinder axis; the extraction opening for the cleaned suspension being provided preferably immediately below the level of the suspension and/or the froth extraction arrangement. | ||||||
