With the so‐called advanced oxidation processes (AOPs) gaining more and more importance, the Fenton process has proven to be a particularly effective method for the treatment of wastewater. 4‐Nitrophenol (4‐NP) was selected as the model pollutant to study the influence of temperature and solar illumination on its degradation rate in batch Fenton and photo‐ Fenton experiments. Based upon these results, the insulated solar Fenton hybrid (ISFH) process was developed, combining solar‐chemical and solar‐thermal processes. With a flat‐plate reactor, it was found to be of particular importance to determine the optimal reactor depth for this continuous process, since excessive reactor depth increased the heat capacity, resulting in an increase of the heating period. Constructive limits were also clearly established.
