In the last decades, the great industrial and demographic development has led to an
unsustainable increase in the consumption of energy and raw materials that negatively affects the
environment. This entails an increase in waste and generated contamination, especially organic
micropollutants that require specific treatments in addition to a high operating cost. Therefore,
alternatives and low cost treatments are studied these days in order to eliminate them effectively
and avoid potential risks to the environment and human health.
Advanced Oxidation Processes (AOPs) are based on their ability to generate hydroxyl
radicals (HO·). The combination of an oxidizing agent (e.g. H2O2), a catalyst (e.g. Fe (ll)) and
energy (e.g., UV radiation) produce this species with a high oxidation potential, which is capable
of oxidizing most compounds in a non-selectively way. In this project, we used metal-based
catalysts for promoting Fenton-like reaction in acidic or neutral pH to wastewater treatment. It is
used to complete mineralization of the pollutants or their degradation in more easily biodegradable
substances. The intention is to develop an effective alternative for elimination of the organic
contaminant of the effluents and to test the use of a low-cost abundant product (waste metal
shavings from metalworking industry) from an economic and environmental point of view.
Zero Valent Iron (ZVI) and waste metal shavings (WMS) from metalworking industry are used
as a catalysts and Sulfamethoxazole (SMX) was selected as model emerging pollutant in
synthetic water. It is studied the different variables to optimize this Fenton-like process as the
conditions of the catalysts and their most optimal concentration.
Fenton oxidation as a combination of waste metal shavings with H2O2 at acid pH to generate
hydroxyl radicals is a potential alternative or a complementary solution to conventional
wastewater treatment processes for industrial wastewater treatment. An advantage it is that the
waste metal shaving can be used over without requiring regeneration or replacement and can be
removed from the treated water by sedimentation or filtration.
