Abstract
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.
