Conventional and Alternative Technologies for the Treatment of Infectious Waste

Abstract The limited scientific information about infectious waste, and the heightened public awareness of this special component of the waste stream, have contributed to the implementation or strengthening of the regulations in this area. This paper proposes a general working definition of infectious waste, and describes the systems used to limit its potential occupational and public health ...

Thermal Treatment Technologies

Hot gas decontamination: Hot gas decontamination is a technology still in the pilot-scale of development that can be used for decontamination of explosives-contaminated masonry or metallic structures. The method involves sealing and insulating the structures, heating with hot gas stream to 260 °C (500 °F) for a prescribed period of time, volatilizing the explosive contaminants, and destroying ...

Biological Treatment Technologies

Decontamination companies and researchers in France are working to restore polluted soil using treatments that range from biological methods to soil washing and incineration. The problem of polluted soil was dramatically illustrated prior to construction of the Stade de France soccer stadium built for the 1998 World Cup. The location of the site, on industrial wasteland just north of Paris, ...

Other Treatment Technologies

Reuse/Recycle: Recovery and reuse technologies for energetic materials, including both explosives and propellants, should be considered at explosives waste sites for several reasons. First, new recovery methods and potential uses for reclaimed explosive materials are rapidly developing. Second, recovery/reuse options reduce overall remediation costs by eliminating destruction costs and allowing ...

Sludge Treatment and Disposal Technologies

Most wastewater treatment processes produce a by-product that purifies wastewater before it is released into local waterways. This by-product is named as sludge. Typically in solid, semi-solid or liquid state, it is in fact an amalgamation of all the liquid wastes that are discharged by domestic houses, commercial properties, industry, and/or agriculture after aerobic biological treatment. ...

Efficient Waste Water Treatment

Clean drinking water is an essential need of mankind. Often surface water like rivers or lakes is used as drinking water source. To prevent these resources from pollution the effective treatment of waste water is a must. For example in China 75% of discharged waste water is coming from pulp and paper, textile and dyeing industries. To run a waste water treatment plant in the most efficient way ...

Waste water treatment technology selection using FAHP and GRA approaches

This paper describes an application of hybrid multi–criteria decision–making (MCDM) technique for the selection of waste water treatment (WWT) technology for treating wastewater. The proposed approach is based on fuzzy analytical hierarchy process (FAHP) and hierarchy grey relation analysis (GRA) technique. The FAHP is used to determine the weights of criteria and then ranking of the WWT ...

econ VacuDry® technology proves successful for the treatment of NORM wastes

Large amounts of drilling sludge containing low levels of natural radioactivity is a resultant by-product of the oil and gas production process. These so-called NORM-sludges (Naturally Occurring Radioactive Material) are often contaminated with both mercury and hydrocarbons. The econ industries VacuDry® technology is recognized in Germany as the first choice for the extraction of the mercury ...

Common Treatment Technologies for Nonhalogenated VOCs

Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

Common Treatment Technologies for Radionuclides in Soil, Sediment, and Sludge

Unlike organic contaminants (and similar to metals), radionuclides cannot be destroyed or degraded; therefore, remediation technologies applicable to radionuclides involve separation, concentration/volume reduction, and/or immobilization. The most commonly used treatment technology for radionuclides in soil, sediment, and sludge is solidification/stabilization (S/S). This treatment technology is ...

Wastewater Treatment Using Crossflow Filtration Technology

Introduction It does not take a great deal of effort these days to recognize the attention being given to water availability and purity. If in a position of consumption, obtaining just a minimum supply is a struggle in some geographical areas. In other areas available water is tainted with contaminants making it unsuitable for use. Further, those fortunate enough to have ample supply in the ...
