Hydrogen Equivalents: Comparison of Simple Electron Donors To EHC ISCR Reagent

Biodegradation via reductive dechlorination processes occurs when microbes directly remove chlorine atoms from a chemical in order to derive energy from other organic compounds. This occurs under reducing, anaerobic conditions. A more effective remedial strategy, however, entails in situ chemical reduction (ISCR) using EHC as the reductant. EHC is the patented combination of controlled-release carbon plus micro-scale zero valent iron particles used for stimulating in situ chemical reduction...

ISCR -- Technology Overview
Biodegradation via reductive dechlorination processes occurs when microbes directly remove chlorine atoms from a chemical in order to derive energy from other organic compounds. This occurs under reducing, anaerobic conditions. A more effective remedial strategy, however, entails in situ chemical reduction (ISCR) using EHC™ as the reductant. As described herein, EHC™ is the patented combination of controlled-release carbon plus micro-scale zero valent iron (ZVI) particles used for stimulating in situ chemical reduction of otherwise persistent organic compounds in groundwater...
