Kinetic and modeling investigations of the anaerobic reductive dechlorination of chlorinated ethylenes using single and binary mixed cultures and silicon-based organic compounds as slow-release substrates

Creator:

Yu, Seungho

Abstract:

This study investigated complete reductive dechlorination of chlorinated aliphatic hydrocarbons (CAHs) over a broad range of concentrations. Tetrabutoxysilane (TBOS), as a slow-release anaerobic substrate, was studied for enhanced reductive dechlorination of tetrachioroethylene (PCE) present as a dense non-aqueous liquid (DNAPL). Four different site-mixed cultures were used in the study: Site-300...

Inhibition, kinetic and modeling studies of acetylene and 1-chloro-1-fluoroethene on reductive dechlorination of TCE and vinyl chloride

Creator:

Pon, George

Abstract:

Laboratory and modeling studies were performed with a mixed-anaerobic-culture obtained from the Evanite site in Corvallis, Oregon. The culture completely transforms trichloroethene (TCE) to cis-dichloroethene (c-DCE), vinyl chloride (VC), and finally to ethene. Acetylene inhibition studies were used to examine the culture's microbial activities. Kinetic studies determined the half-saturated constant...
