Processing Hazardous Waste

AVA is one of the leading suppliers of machines and system solutions having its core competencies in mixing and drying of any kind and in any industry. One of AVA’s vital businesses lies in developing and supplying turn-key (mobile) plants for processing contaminated recyclables and wastes using high vacuum and/or high temperatures. ...

Response of fish tissue mercury in a freshwater lake to local, regional, and global changes in mercury emissions

by John Wiley & Sons, Ltd.  (Mar. 21, 2014)

A suite of mechanistic atmospheric and mercury cycling/bioaccumulation models is applied to simulate atmospheric mercury deposition and mercury concentrations in the water column and fish in a mercury‐impaired freshwater lake located in the northeastern United States that receives its mercury loading primarily through deposition. Two ...

VacuDry Indirect heated vacuum thermal Desorption by econ industries - case study

by econ industries GmbH  (Feb. 6, 2014)

With the VacuDry8 technology the energy-efficient treatment of hazardous and industrial waste as well as contaminated soil, oil sludge and secondary raw material is realized. Controlled vacuum and heat are used to separate minerals from oil, solvents, mercury and other hazardous substances.    At the core of the econ VacuDry8 ...

Remediation of mercury contaminated industrial site for future expansion - case study

by econ industries GmbH  (Feb. 4, 2014)

70,000 tons of mercury contaminated soil and building rubble have to be cleaned in an industrial facility in the south of France until 2013. For the realization of this remediation work, an econ industries VacuDry® 12,000 has been in operation since early 2011. After the treatment the mercury free soils can be re-used on-site as building ...

Recycling plant for multiple types of fluorescent lamps - case study

by econ industries GmbH  (Feb. 4, 2014)

The fluorescent lamps recycling plant was designed for a Taiwanese recycling company. The task was to develop a treatment plant which achieves a high recycling quota while keeping the investment level moderately low. This was achieved by combining several specially developed technologies. These techno- logies include a high efficient ...

Sensitive quantification of trace zinc in water samples by adsorptive stripping voltammetry

by IWA Publishing  (Jan. 29, 2014)

A simple and sensitive adsorptive stripping voltammetry method was developed for determination of Zn using N-nitrozo-N-phenylhydroxylamine (cupferron) as a selective complexing agent. This complex absorbed on the hanging mercury drop electrode and created a sensitive peak current. The peak current and concentration of zinc accorded with a linear ...

Lifelong exposure to methylmercury disrupts stress‐induced corticosterone response in zebra finches (Taeniopygia guttata)

by John Wiley & Sons, Ltd.  (Jan. 16, 2014)

Mercury can disrupt the endocrine systems of mammals and fish, but little is known about its effects on avian hormones. We employed an experimental manipulation to show that methylmercury suppresses the stress‐induced corticosterone response in birds, an effect previously unreported in the literature. Corticosterone regulates many normal ...

Effects of macrophytes on the fate of mercury in aquatic systems

by John Wiley & Sons, Ltd.  (Dec. 24, 2013)

Vegetated and shallow areas such as wetlands and salt marshes but also freshwater lakes and rivers have been identified as hotspots for Hg methylation. The presence of aquatic macrophytes, the predominant primary producers in shallow waters, play an important but still poorly understood role in the fate of Hg in in these environments. The ...

Combating Corrosion within Power Generation Facilities

by Sauereisen Inc  (Dec. 9, 2013)

Just about every utility facility that generates power or engages in some form of incineration must deal with corrosion issues. Since the ac Air Act of 1990, gas-scrubbing technologics have increased the im serving the assets of power plants and othe incineration infrastructure. These demands will increase further with the advent of new mercury ...

Human mercury exposure and effects in Europe

by John Wiley & Sons, Ltd.  (Dec. 4, 2013)

The effects of human exposure to mercury (Hg) and its compounds in Europe have been the focus of numerous studies that differed in their design, including recruiting different population groups at different levels of exposure and by using different protocols and recruitment strategies. The objective of this work was to review current studies of ...
