Large-scale contaminated sites with multiple contaminants in the groundwater present a challenge to risk assessment (Heidrich et al. 2004; Heidrich 2004) and an economic burden at many industrial as well as urban groundwater monitoring sites (UIZ 2015).
The method is tested on a hypothetical aquifer remediation scenario and an actual large-scale contaminated site, illustrating the cost-effectiveness of the method.
Nanoremediation has the potential to reduce the overall costs of cleaning up large-scale contaminated sites, reduce cleanup time, eliminate the need for treatment and disposal of contaminated dredged soil, and reduce some contaminant concentrations to near zero, and it can be done in situ.
Large-scale contaminated megasites like Bitterfeld in eastern Germany are characterized by a regional contamination of soil, surface water and groundwater as a result of a long and varied history of chemical production.
Radial Basis Functions collocation method is used to simulate different spatial arrangements of the cylinders to understand the behavior of the system and gain insight into designing a remediation strategy for a large-scale contaminated region.
Nanoremediation has the potential not only to reduce the overall costs of cleaning up large-scale contaminated sites but also to reduce cleanup time, eliminate the need for treatment and disposal of contaminated soil, and reduce some contaminant concentrations to near zero all in situ.
For example, Ding et al. (2012) investigated the removal of Cd2+ from large-scale effluent contaminated by heavy metals.
These results should help in determining the best bioremediation method and improving the design and operation of large scale clean up of contaminated sites by bioremediation systems.
The results obtained for the adsorptive removal of As V) by the selected biosorbent suggested its possible application in large scale treatment of As V) contaminated water bodies.
Hence, the designed column reactor could be used successfully at a large scale for treatment of water contaminated with various aromatic compounds.
