Abstract: The noxious element arsenic may be removed with high efficiency from iron hydroxide sludge by first subjecting that sludge first to a thermal treatment in the presence of air or oxygen and of an alkaline reagent and next extracting the treated material with water. The arsenic present in the extract is thereupon adsorbed to an anion exchanger, eluted with an alkaline aqueous liquid and precipitated in salt form from it. The residual sludge is better suitable for re-use or for another useful application. The method may also be used for removing other amphoteric elements such as P, Cr, Al, Mn, Zn and the like and is not only applicable to iron hydroxide sludge but also to other sludge types and several types of solid waste materials.

Abstract: An advancing freeze front is established in a porous region (16) adjacent to or within contaminated earth (12). A flow of contaminated liquid phase water migrates toward the freeze front and a concentration of impurities is established in front of the advancing freeze front. When the freeze front reaches a collection zone, at least a portion is melted and the resultant water bearing concentrated impurities is collected and removed. This process may be repetitively performed.

Abstract: Environmentally harmful waste is hard to handle and the capacity for an economical handling is not sufficient. According to the invention such waste can now be worked up to a full worth fuel which can replace conventional fuels, which can be stored and has a specific composition and which gives little harmful air pollution, and a solid residue which can be deposited cheap and safe. According to the invention the waste is fractionated in centrifuges or cyclones (5, 10) into a solid part, in which the main part of the heavy metals in the waste are enriched and a liquid part containing oils, solvents and dissolved substances. The solid part containing plastics, pigments, insoluble oil residues, organometallic compounds, etc. is mixed, after drying (12) and optional grinding with other wastes, such as Cefyll with which it can form a very sparingly soluble, monolithic compound and be deposited. The liquid part is used as a fuel.

Abstract: Process and device for treating contaminated soil and similar materials by the removal, decontamination and possible refilling of the place concerned with cleansed soil. The soil removed is dried and crushed in a mill (2, 29, 57) through which passes a stream of hot gases, and the solid-gas mixture thus formed is taken to a cyclone separator (4, 31, 58) and separated there into gaseous and solid components. The solids are heat treated at high temperature (6, 32, 60) in an initial decontamination process. Following a further separation of the solid and gaseous phases in a further cyclone (8, 34, 62), the solids which are still at least partly contaminated are taken to an intermediate storage area (9, 35, 63) in the form of a transit region and further treated there at temperatures essentially corresponding to the decontamination temperature. The exhaust gases from the drying of the crushed material are after-burnt (16, 42, 75) and, for energy-saving reasons, at least partly re-used in the decontamination process.

Abstract: A method and apparatus for decontaminating ground areas where toxic chemicals are buried comprises disposition of a plurality of spaced electrodes (13, 14, 21, 22) in the ground to be treated and application of a voltage across the electrodes for bringing about current flow through the ground. Power delivered to the ground volatilizes the chemicals which are collected and directed to a gas treatment system. The preferred form of the invention employs high voltage arc discharge between the electrodes for heating a ground region to relatively high temperatures at relatively low power levels.
