WebApr 1, 2016 · Remediation of TCE-contaminated sites is not an easy task because of the complex distribution of TCE throughout the subsurface. Bioremediation has been applied as a remedial strategy to clean up TCE-contaminated aquifers. In situ reductive dechlorination of TCE operates under anaerobic conditions, which results in the … WebAbstract The use of colloidal biliquid aphron (CBLA) as density modifier to reduce the density of dense nonaqueous phase liquids (DNAPLs) irreversibly is an efficient strategy to control the migration of DNAPLs in contaminated aquifers. However, the process and mechanism of the density regulation using CBLA is still not clear and there is still a big … WebThe bioremediation project is a bench-scale microcosm study to determine if biodegradation of tetrachloroethylene (PCE) is possible using native bacteria from a … theos offenbar
