Development of Activity Enhanced Zero Valent Metals for Permeable Reactive Barrier

Microbiological characteristics in a zero-valent iron reactive barrier.

Zero-valent iron (Fe0)-based permeable reactive barrier treatment has been generating great interest for passive groundwater remediation, yet few studies have paid particular attention to the microbial activity and characteristics within and in the vicinity of the Fe0-barrier matrix. The present study was undertaken to evaluate the microbial population and community composition in the reducing ...

Long-Term Performance of Zero-Valent Iron Permeable Reactive Barriers: A Critical Review

Permeable reactive barriers (PRBs) have shown great promise as an alternative to pump and treat for the remediation of groundwater containing a wide array of contaminants including organics, metals, and radionuclides. Analyses to date have focused on individual case studies, rather than considering broad performance issues. In response to this need, this study analyzed data from field installat...

Long-term Performance of Permeable Reactive Barriers Using Zero-valent Iron: An Evaluation at Two Sites

The permeable reactive barrier (PRB) technology is an in-situ approach for remediating groundwater contamination that combines subsurface fluid flow management with a passive chemical treatment zone. Removal of contaminants from a groundwater plume is achieved by altering chemical conditions in the plume as it moves through the reactive barrier. Because the reactive barrier approach is a passiv...

investigation of hexavalent chromium cr (vi) removal from contaminated clayey soil by simultaneous combination of electro kinetics and nano zero-valent iron as a permeable reactive barrier

recently, a variety of soils contaminated with heavy metals e.g. cr (vi), have been found in industrial sites. such soil contamination is widely distributed in the world and has now become a serious issue for environment. hexavalent chromium, cr (vi), which is known to be carcinogenic and mutagenic to living organisms, has been utilized for leather tanning, electroplating and in other industrie...
