11 Capable to generate non selective, highly oxidizing species. Able to degrade organic compounds or mineralize it to CO 2 and water. Some AOPs may use solar radiation as driven force in restoration processes. Solar photocatalysis (SP) is the AOP currently in use for water treatment Advanced Oxidation Processes (AOPs)

19 Conclussions Water decontamination and disinfection is possible using solar driven advanced oxidation processes. Fenton and Fenton like processes demonstrate high efficiency for organic pollutants degradation in short periods of time. Some of these processes are currently on use at industrial application in developed countries. It is interesting assess the feasibility of using experience generate so far for applications in our country.
