Evaluation of the Partial Ozonation and Partial Hydrogen Peroxide Oxidation Process for the Removal of COD and Estrogenic Activity from a Tank Truck Cleaning Generated Concentrate

摘要

The internal cleaning of tank trucks gives rise to a highly variable and complex wastewater often containing significant amounts of persistent organics and toxic micro-pollutants. This paper evaluates the use of partial chemical oxidation to remove COD and estrogenic activity from a tank truck cleaning generated wastewater concentrate. Following ranking of processes regarding removal efficiency was established: direct partial ozonation (pH 7.5) advanced partial ozonation (pH 11.5) partial hydrogen peroxide oxidation. Wastewater estrogenic activity (1.78 ng/L 17β-estradiol equivalents) is effectively lowered below the detection limit of the applied MCF-7 cell proliferation assay by all studied oxidation processes.View full textDownload full textKeywordsOzone, Hydrogen Peroxide, MCF-7, Endocrine Disruption, Wastewater Concentrate, Estrogenic Activity, Tank truck CleaningRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/01919512.2012.639663
