A Risk/Benefit Appraisal for the Application of Nano-Scale Zero Valent Iron (nZVI)
NanoRem (Taking Nanotechnological Remediation Processes from Lab Scale to End User Applications for the Restoration of a Clean Environment) is a research project, funded through the European Commission’s Framework 7 research programme. NanoRem focuses on facilitating practical, safe, economic and exploitable nanotechnology for in situ remediation. This is being undertaken in parallel with ...

Full-scale application of nZVI: remediation of deep contamination plume close to source of drinking water
Treatment of an old disposal site proved to be a challenging task due to its improper placement and insufficient ensuring. The site is located in a very complex geological environment and in imminence of the source of drinking water. Therefore, the soluble in-situ reagents cannot be applied here. NANOFER slurry was chosen by the remediation company AQUATEST for removal of chlorinated hydrocarbons ...

Transport of sucrose-modified nanoscale zero-valent iron in saturated porous media: role of media size, injection rate and input concentration
The growing use of nanoscale zero-valent iron (NZVI) in the remediation of contaminated groundwater raises concerns regarding its transport in aquifers. Laboratory-scale sand-packed column experiments were conducted with bare and sucrose-modified NZVI (SM-NZVI) to improve our understanding of the transport of the nanoparticles in saturated porous media, as well as the role of media size, ...

Reclamation of unconventional water using nano zero–valent iron particles: an application for groundwater
Nano zero–valent iron (nZVI) is one of the most prominent examples of a rapidly emerging technology for the treatment of contaminated soil and groundwater. These particles were used successfully to absorb various heavy metals (e.g., Pb2+, Ba2+, As5+, As3+, Cr6+, Co2+, Cd2+, Cu2+), chlorinated organic contaminants (e.g., solvents, pesticides), nitrate and so on. nZVI particles have a large ...

Former Dry Cleaning Site Contaminated with PCE - Case Study
In-Situ® Inc. TROLL® 9500 Multiparameter Sonde helps resolve treatment challenges and saves $200,000 in drilling, reagents, and consulting. A former dry-cleaning site in the Pacific Northwest, Ultra Custom Care Cleaners, was found to be contaminated with PCE (perchloroethylene). According to the U.S. Geological Survey (USGS), PCE was widely used in the dry cleaning of fabrics since the ...
