Journal ArticleDOI
Removal of arsenic from contaminated water sources by sorption onto iron-oxide-coated polymeric materials.
TL;DR: Though, among the examined materials, polyHIPE was found to be more effective in the removal of arsenic, as far as it concerns the maximum sorptive capacity before the filtration bed reaches the respective breakthrough point.
Journal ArticleDOI
pH Dependence of Fenton Reagent Generation and As(III) Oxidation and Removal by Corrosion of Zero Valent Iron in Aerated Water
TL;DR: Experimental data and kinetic modeling suggest that As(III) was oxidized mainly in solution by the Fenton reaction and removed by sorption on newly formed hydrous ferric oxides, whereas a more selective oxidant oxidizes As( III) at circumneutral pH.
Journal ArticleDOI
Application of biological processes for the removal of arsenic from groundwaters.
TL;DR: The results showed that both inorganic forms of arsenic could be efficiently treated, for the concentration range of interest in drinking water (50-200microg/L), and the oxidation of trivalent arsenic was found to be catalyzed by bacteria, leading to enhanced overall arsenic removal.
Journal ArticleDOI
Efficiency and energy requirements for the transformation of organic micropollutants by ozone, O3/H2O2 and UV/H2O2.
TL;DR: In this article, the authors compared the energy consumption of conventional ozonation and the AOPs O(3)/H(2)O(2), and UV/H( 2)O (2) for transformation of organic micropollutants, namely atrazine (ATR), sulfamethoxazole (SMX) and N-nitrosodimethylamine (NDMA), in three lakes and a wastewater.
Journal ArticleDOI
Biological treatment of Mn(II) and Fe(II) containing groundwater: kinetic considerations and product characterization.
TL;DR: The kinetic results indicated that the rates of manganese and iron oxidation were several orders of magnitude greater than the respective for abiotic oxidation.
