A built-in zero valent iron anaerobic reactor to enhance …

The ZVI acted as a reductant to decrease ORP in the reactor by more than 40 mv and functioned as an acid buffer to increase the pH in the reactor from 5.44 to 6.29, both of which improved the performance of the anaerobic reactor. As a result, the removal of color and COD in this reactor was 91.7% and 53%, respectively, which was significantly ...

Synergistic Zerovalent Iron (Fe0) and Microbiological …

Trichloroethene (TCE) and perchlorate (ClO4–) are cocontaminants at multiple Superfund sites. Fe0 is often used during TCE bioremediation with Dehalococcoides mccartyi to establish anoxic conditions in the aquifer. However, the synergy between Fe0 abiotic reactions and microbiological TCE and ClO4– reductions is poorly understood and seldom addressed in the literature. Here, …

What is Zero Valent Iron?

Zero Valent Iron (ZVI), elemental metallic iron, reduces waterborne inorganic ions, releasing soluble Fe (ll) in their place, which oxidizes further into Fe (III). Coal mining drainage is an example where ZVI has treated contaminated water safely, effectively and economically. In chemical terms, ZVI describes the elemental form of iron, and ...
