  • Evolution of the sewage treatment plant model SimpleTreat: Applicability domain and data requirements

    SimpleTreat 3.1 is the sewage treatment plant (STP) model implemented in the EU framework for the environmental risk assessment of chemicals. The model was originally designed for neutral hydrophobic chemicals, while many substances currently under regulatory scrutiny, are ionisable at environmental pH. Although the model has been adapted to describe ionisation (SimpleTreat 3.1), the fate of ...

  • Restoration of high zinc and lead tailings with municipal biosolids and lime: a field study

    Received for publication February 26, 2008. A field study was conducted to test the ability of biosolids (BS) and different types of lime to increase soil pH, neutralize subsoil acidity, and restore a vegetative cover to alluvial mine tailings in Leadville, CO. The tailings had soil pH of 5.2 and total Cd, Pb, and Zn of 75 ± 20, 2600 ± 1100, and 6700 ± 1900 mg kg–1. Types of lime included ...

  • Comparison of Fenton and Fenton-like oxidation for the treatment of cosmetic wastewater

    The treatment of cosmetic wastewaters by Fenton (Fe2+/H2O2) and Fenton-like (Fe3+/H2O2) oxidation has been studied. From batch and continuous experiments it has been proved that both versions of the Fenton process lead to quite similar results in terms of chemical oxygen demand (COD) and total organic carbon reduction although ...
