Low cost UVA-LED as a radiation source for the photo-Fenton process: a new approach for micropollutant removal from urban wastewater

A UVA-LED driven photo-Fenton process is shown as a feasible technology for micropollutant removal. The photoreactor design, which strongly depends on the energy efficiency and LED wavelength, needs to be carried out using parameters such as Electrical-Energy-per-Order (EEO).
