Treatment of real wastewater from the graphic industry using advanced oxidation technologies: Degradation models and feasibility analysis

Many organic contaminants present in industrial effluents are resistant to conventional treatments. The application of Advanced Oxidation Technologies (AOT's) to a system of great complexity and unknown composition was studied. The proposed AOT's arise from the combination of UV light irra...

description Many organic contaminants present in industrial effluents are resistant to conventional treatments. The application of Advanced Oxidation Technologies (AOT's) to a system of great complexity and unknown composition was studied. The proposed AOT's arise from the combination of UV light irradiation (254 nm) in the presence of commercial steel wool (CSW - zerovalent iron) and H2O2 as an oxidant, resulting in degradation processes by UV photolysis, UV/H2O2, Fe°/H2O2 and UV/H2O2/Fe°. The system used was an effluent from a graphic industry. High organic load and low biodegradability are characteristics of these wastewaters. The CSW was characterized by SEM/EDS. The effect of pH, H2O2 concentration, mass of CSW, intensity of UV light and temperature on the reduction of chemical oxygen demand (COD) of the effluent was evaluated employing a screening design. Afterwards, significant factors ([H2O2], light intensity and temperature) were selected to study their effect on COD reduction employing a central composite design. Optimum operating conditions predicted (0.06 mol L− 1 of H2O2, UV254 nm of 1.6 × 10− 5 E s− 1 and 44 °C at pH ca. 6.5.) generated an experimental COD reduction of 98.22% at lab scale. These conditions were also tested at pilot scale. Furthermore, phytotoxicity of treated effluents was analyzed.
