Large Laboratory-Plant application for the treatment of a Tannerywastewater by Fenton oxidation: Fe(II) and nZVI catalysts comparisonand kinetic modelling
This study reports a comparison among Conventional Fenton oxidation (CF) and Heterogeneous Fenton oxidation (HF) processes performed at large lab-scale on a Tannery Wastewater (TW). The heterogeneous Fenton process was carried out by using self lab-prepared nano zero-valent iron particles as solid catalyst. Two different catalyst/oxidant (Cat/Ox) (w/w) ratio were examined: a study on the pH solution influence on the process efficiency, monitoring the COD, TP, H2O2 and Cr(VI) variation over the reaction time was carried out.
