A variety of column experiments have been completed for the purpose of selecting and evaluating suitable surfactants for remediation of nonaqueous phase liquids (NAPLs).
Besides the metal extraction, Salix caprea represents a suitable candidate for remediation because of fast colonization of mineral substrates, high biomass production and landscape restoration.
The properties making Fe0 suitable for environmental remediation include: (1) its readily availability and (2) its environmental friendliness implying the generation of non-toxic hydroxides and oxides.
Finally, it can be concluded that the configuration of this reactor is suitable for the remediation of this type of effluents.
It should be noted, however, that not all sites have conditions suitable for nanoscale remediation methods.
The study demonstrated that CW seems suitable eco-technology for remediation of urban wastes containing trace elements and high nutrients, before entering into Ganga River.
This paper aims to propose a reactor design suitable for in situ groundwater remediation and characterise it with respect to the surface area to volume ratio, aeration, flow and reliability.
There are many specialty carbons available in the market, but those most suitable for use in sediment remediation will have good sorption properties for the target contaminant (PCBs or Hg for example), will need to have no inherent toxicity, and will need to be low-cost.
Environmental isotopes can be used to know the contaminant pathways and thereby assist in predicting the spatial distribution and temporal variations in contamination levels for planning suitable aquifer remediation measures.
