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...
متن کاملLong-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...
متن کاملCharacterization of zero-valent iron nanoparticles.
The iron nanoparticle technology has received considerable attention for its potential applications in groundwater treatment and site remediation. Recent studies have demonstrated the efficacy of zero-valent iron nanoparticles for the transformation of halogenated organic contaminants and heavy metals. In this work, we present a systematic characterization of the iron nanoparticles prepared wit...
متن کاملMicrobiological 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 ...
متن کاملtreatment of landfill leachate by fenton process with nano sized zero valent iron particles
leachate treatment from municipal landfills has been always a major anxiety in waste management due to its high level of various contaminations. in this paper the effect of nanosized zero valent iron particles (nzvi) in fenton process for the treatment of high cod strength landfill leachate was scrutinized. the results corroborated this procedure was fast and efficient. in fact, about 87% of in...
