Photo-Fenton is one of the most efficient water treatments among the Advanced Oxidation Processes. Complexing the iron with organic ligands allows working at a neutral pH and increases the Photocatalytic activity of the system, expanding the fraction of usable solar radiation. These enhancements eliminate the costs associated with consumption of electricity from the lamps (if natural solar energy is used) and from the pH adjustment before and after the treatment. Then, the oxidizing agent can be considered the main source of costs. An alternative that would reduce its consumption is hydrogen peroxide (HP) dosage during the degradation process.
