Bioremediation of tce
WebMar 20, 2024 · 1. Introduction. Chlorinated solvents are commonly found organic pollutants in contaminated groundwater. Trichloroethylene (TCE), a dense non-aqueous-phase liquid (DNAPL) pollutant, is one of the chlorinated organic compounds among the soil and groundwater pollutants (Moccia et al., 2016).In situ bioremediation meets the … WebDuring the experiments, 85-101% of the degraded TCE chlorine was recovered as chloride. Overall, the results suggest that the FEBR can be a very effective system to treat TCE vapors cometabolically.
