i <br /> i <br /> Embedment—the incorporation of waste masses into a solid matrix before disposal. <br /> Emerging Technologies—technologies that are still being designed, modified, and tested in the <br /> laboratory and are not available for full-scale implementation (e.g., plasma-arc ultrahigh-temperature <br /> ! process, or hydrodehalogenation with atomic or molecular hydrogen under the presence of heat, <br /> pressure, and catalyst). <br /> Emulsifier—a substance used to produce an emulsion of two liquids which do not naturally mix. <br /> Emulsion—a colloidal mixture of two immiscible fluids, one being dispersed in the other in the form of <br /> fine droplets. <br /> Equilibrium Leach Test (ELT) —a leaching test in which, under the conditions of the test, an equilibrium <br /> between the specimen and the leachant is attained. <br /> Ettringite—a mineral composed of hydrous basic calcium and aluminum sulfate. The formula for <br /> ettringite is Ca6Al2(SO4)3(OH)12.26 H2O. <br /> Expression—physical removal of liquid from a solid/liquid mixture by application of pressure. <br /> Extender—an additive the primary function of which is to Increase the total bulk of the S/S-treated <br /> waste. <br /> Extraction Procedure Toxicity Test (EP Tox) —a regulatory leaching test used since 1980 to determine <br /> if a waste is toxic (40 CFR Part 261, Appendix 11). <br /> Fate and Transport—analysis of movements and transformations of contaminants through the <br /> environment from a source to a receptor. <br /> Feasibility Study (FS)—a study undertaken to develop and evaluate options for a treatment process. <br /> Filtration— a process that involves passing a slurry through a porous medium in which the solids are <br /> trapped and the liquid passes through. <br /> Flame Reactor—a treatment method developed by the Horsehead Resource Development Company <br /> (HRD) to recover cadmium, lead, and zinc from complex solid materials. The HRD Flame Reactor <br /> technology is'a two-stage treatment method. In the first stage, carbonaceous fuel is combusted with <br /> oxygen-enriched air under fuel-rich conditions (burner section). The combusted waste is pneumatically <br /> injected into the hot (2,200 to 2,500('C) reducing flame in the second stage (reactor section). The <br /> intensive process conditions allow reaction times to be short (less than one-half second) and permit a <br /> high waste throughput. Close control of the operating parameters enables extraction of valuable metals <br /> and destruction of hazardous organic constituents. <br /> Flue Gas Desulfurization (FGD)—a pollution abatement process. <br /> Fly Ash—the finely divided residue from the combustion of ground or powdered coal which is <br /> transported from the firebox through the boiler by flue gas. <br /> Fourier Transform Infrared Spectroscopy (FTIR)—a microcharacterization method. <br /> Free Water—water that is free to move through a soil or rock mass under the influence of gravity. <br /> K-5 <br />
