A process for decontaminating a medium polluted with metals and hydrophobic organic compounds (HOC) includes providing an acidic slurry of water, acid, chloride salt, surfactant, and the polluted medium. Flotation is preformed on the acidic slurry to form a HOC-rich froth and an HOC-depleted slurry and the froth is recovered. The slurry is separated to obtain a treated solid and a liquid effluent rich in metallic ions. Preferably, the process also includes recuperating the metals by chemical precipitation and/or electrodeposition to produce a treated solution. Also provided are a decontaminant having an acid, a chloride salt, and a surfactant as well as a chemical kit for decontaminating the polluted medium including the decontaminant in which the acid, chloride salt and surfactant can be mixed with polluted medium in the presence of water before removing at least a portion of the metals and HOC from the polluted medium.

A froth flotation process typically used to separate particulate materials such as coal, has a mixed size feed ( 1 ) separated in a sieve bend ( 2 ) into a stream of relatively fine particles ( 3 ) and a stream of relatively coarse particles ( 14 ). The fine particles are fed to a flotation cell ( 7 ) in the normal manner, while the coarse particles are mixed with wash water ( 16 ) and distributed onto or into the froth layer ( 10 ) by wash water distribution apparatus ( 19, 20 ). Alternative variations of wash water distribution apparatus able to handle coarse particles are also described.

272	IMPROVEMENTS IN OR RELATING TO SEPARATION PROCESSES	EP99919396.4	1999-04-28	EP1073716B1	2004-04-28	CUTHBERTSON, Alan,Amersham Health AS; RONGVED, Pal; L VHAUG, Dagfinn,Amersham Health AS; FJERDINGSTAD, Hege,Amersham Health AS; SOLBAKKEN, Magne,Amersham Health AS; GODAL, Aslak
Separation of target material from a liquid sample is achieved by coupling the target to targetable encapsulated gas microbubbles, allowing the microbubbles and coupled target to float to the surface of the sample to form a floating microbubble/target layer, and separating this layer from the sample. In a positive separation process the microbubbles are then removed from the target, e.g. by bursting. In a negative separation process target-free sample material is recovered following separation of the floating layer. The method may also be used diagnostically to detect the presence of a disease marker in a sample. Novel separation apparatus is also described.
273	PROCESS AND DEVICE FOR FAT SEPARATION	EP01975131.2	2001-10-10	EP1332113A1	2003-08-06	AXELSSON, Niklas, Wihelm
Process and equipment for separating fat from waste water and reducing the amount of fat that has to be taken care of from restaurants, bakeries, food industries etc. While wastewater is added the equipment functions as a conventional fat separator, i.e. collects and accumulates fat. When the daily shutdown begins the equipment is converted to a bioreactor. In this bioreactor the accumulated fat is remixed with water and broken down biologically with the aid of microorganisms, which break down fat, proteins, starch etc. The microorganisms are added as a liquid culture of living organisms. Co-ordination of air injection and addition of the liquid culture achieve even distribution of microorganisms. The bioreactor function is sustained by air injection and ceases when the air injection is shut off. Equipment for converting a conventional fat separator to a fat separator/bio-reactor is described.
274	METHOD AND APPARATUS FOR MONITORING AND ANALYZING THE SURFACE OF FLOATED MATERIAL	EP00927265.9	2000-05-05	EP1190237A1	2002-03-27	NIEMI, Antti Johannes
At the separation of different minerals from the ores by means of flotation, it belongs to known art to monitor a larger part of the uppermost froth layer in the flotation cell by means of a video camera whose signals are analyzed in a digital computer, in order to detect the structure and color of the froth. The new method and apparatus direct and limit the monitoring and analysis to the surface of the floated material within a fixed, narrow strip which is parallel to the overflow edge of the cell and within which the material surface passing it is homogeneous in the stationary state. The said strip thus presents a renewing sample of the surface at the location in question, which sample represents the stationary state in the average sense. The strip is subjected to homogeneous illumination, which may meet the strip at different angles depending on the primary object, i.e. whether the color or structure is being determined. By means of a repeatedly reading semiconductor line array camera, the image of the strip is formed and converted to electric black/white or multicolor signals from which the structure or color quantities are determined in digital computer. The monitoring and analysis can be directed to both the surface of the froth layer and the surface of the froth slurry flowing down from the overflow edge.

A combination of raw coal and water is introduced as a slurry (23) into a vessel (12). Chemicals are introduced at a feed inlet. The mixture is reduced by interaction with a bed of agitated (15,16) grinding balls (14). Air is introduced into the lower portion of the vessel and forced upwardly through the circuitous passages among and between the grinding balls. The rising air bubbles carry the more hydrophobic product upwardly into a froth compartment (34) of the vessel (12) and through a discharge outlet (36) of the vessel. Wash water (37) is introduced into the upper portion of the vessel and descends through the froth and the ball passages carrying entrained and less hydrophobic particles into the grinding chamber (40). The non-floatable material flows downwardly from the grinding chamber (40) to a refuse zone (42) for discharge (45) as refuse from the vessel.

A separation system is presented that partitions a slurry containing a plurality of particles that are influenced by a fluidization flow (which comprises teeter water and gas bubbles) and a fluidized bed. The separation system comprises a separation tank, a slurry feed distributor, a fluidization flow manifold and a gas introduction system. All of these components are arranged to create the fluidized bed in the separation tank by introducing the slurry through the slurry feed distributor and allowing the slurry to interact with the fluidization flow that enters the separation tank from the fluidization flow manifold. The gas introduction system is configured to optimize the gas bubble size distribution in the fluidization flow. The gas introduction system comprises a gas introduction conduit and a bypass conduit. The gas introduction system can be adjusted by modulating the flow of teeter water through the gas introduction conduit.
