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 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 کاملinvestigation 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...
متن کاملحذف تتراسایکلین از محلول های آبی طی فرآیند Nano Zero Valent Iron/UV/H2O2
زمینه و هدف: حضور باقیمانده آنتی بیوتیک ها در محیط زیست امروزه به عنوان یکی از نگرانی های جهانی مطرح شده است و لزوم کنترل تخلیه آنها نیز بعنوان امری اجتناب ناپذیر مطرح شده است. این تحقیق، با هدف بررسی کارایی فرآیند تلفیقی شبه فنتون (UV/H2O2/nZVI) جهت تجزیه آنتی بیوتیک تتراسایکلین از محیط های آبی صورت گرفت. مواد و روشها: این تحقیق یک مطالعه تجربی بود که در مقیاس آزمایشگاهی و در دمای محیط انجام ...
