contaminant transport Applications

Temperature is an important factor in streams ecosystems. Heat tracers have been used to characterize contaminant transport, infiltration rates and energy exchange with groundwater, the atmosphere and radiation. The dynamics of these complicated water bodies is also affected by seasonal and diurnal patterns making characterization particularly challenging. Utilizing temperature measurements that capture spatial and temporal variations at stream ecosystem interfaces provides a mechanism for detailed characterization...

When concrete is contaminated with PCBs, radiation or other hazards, scabbling is often the only means of remediation. By removing a thin outer layer from a concrete surface, our shrouded power tools can make a structure safer for occupancy or demolition. Our powerful VAC-PAC® HEPA vacuum captures all dust, debris, and air-borne contaminants for easy transportation and disposal in standard 55-gallon (200L) drums. Whether you’re applying a new coating system or a concrete overlay, a Concrete Surface...

Mechanical treatment as the foundation for recycling: The reuse of materials and energy from waste is central to modern waste management. The foundation for it is laid by mechanical preparation in the form of waste splitting. In it, recyclables are recovered from the waste stream and high-yield combustibles are separated out for further processing as refusederived fuels (RDF). The remaining residue fraction can be stabilized and then landfilled.

ISTD (In Situ Thermal Desorption) = no excavation needed. It often occurs that real estate companies are confronted with contaminated soil in a property, creating a legal and financial problem for transfer of ownership.

Subsurface environments are critical not only as water resources but also for energy use including geothermal, CO2 sequestration and oil & gas operations. These sensitive environments are directly affected by anthropogenic activities, hence monitoring is essential. Temperature offers insight into a variety of physical properties and can be used for flow monitoring and flux quantification in the subsurface. Traditionally, point sensors have been used to collect temperature data; however, significant limitations...

Dewatering rejects to maximum dry contents represents an essential process step both from an economical and ecological viewpoint, especially in waste paper based paper mills but also in pulp mills. The following goals shall be achieved: high heating value for stable and ecological incineration without co-firing, reduction of landfill and transport charges.
