This study evaluated the effectiveness of sequential anaerobic/aerobic biodegradation of
tetrachloroethene (PCE) and its intermediates, cis-1, 2-dichloroethene (cDCE) and vinyl …

A novel aerobic/anaerobic/aerobic treatment was implemented in batch reactors containing
aquifer materials from a site contaminated by tetrachloroethylene (PCE), trichloroethylene …

Chlorinated aliphatic hydrocarbons generally cannot be used as the carbon source or
energy source for microorganism growth; these compounds are more difficult to be …

Chlorinated ethene (CE) groundwater contamination is commonly treated through anaerobic
biodegradation (ie, reductive dechlorination) either as part of an engineered system or …

Trichloroethylene (TCE) and perchloroethylene (PCE) are two of the most frequently
detected chlorinated organics found in groundwater. Biodegradation with a new aerobic …

Degradation of the lower chlorinated ethenes is crucial to the application of natural
attenuation or in situ bioremediation on chlorinated ethene contaminated sites. Recently …

Chlorinated ethenes (such as tetrachloroethylene, trichloroethylene, etc.) are volatile
organic solvents widely used as cleaning agents, have biological toxicity (Spencer et al …

Intrinsic biodegradation of trichloroethene and 1, 1, 1-trichloroethane in groundwater at a
Superfund site in California has been observed. An anaerobic zone exists in the area …

Chlorinated ethenes have been widely used as solvents and agents in dry cleaning,
degreasing, and various manufacturing processes. Before the 1980's, little control on the …

This study is aimed at investigating the performance of the continuous-flow, two-stage
anaerobic column for the reductive dechlorination of perchloroethene (PCE) in a …
