Summary
The solar chloro-photo-Fenton process has recently been proposed as a new photo-Fenton strategy, combining the high bacterial inactivation efficiency of sodium hypochlorite (NaClO) with the micropollutant removal capacity of the photo-Fenton process. In this way, both treatment objectives could be achieved in a shorter time than other solar processes, obtaining reclaimed water free of NaClO disinfection by-products (DBPs), which could be used for agricultural irrigation, reducing operating costs and the environmental risk associated with its reuse. In order to facilitate the commercial application of the chloro-photo-Fenton process, it is essential to investigate its operational feasibility in continuous flow. Furthermore, the study of disinfection and micropollutant removal mechanisms is essential for the development of models to design and optimise the operation of photoreactors. In this context, as an initial hypothesis of the NEREIDAS project, the possibility of using and optimising the operation of continuous solar chloro-photo-Fenton reactors for the regeneration of wastewater for reuse in agricultural irrigation in accordance with Regulation (EU) 2020/741 is proposed.
The general objective of the project is the development of a mechanistic model of the solar chloro-photo-Fenton process to optimise the continuous flow operation of raceway reactors for the regeneration of wastewater in compliance with the new European regulations, from an economic-environmental sustainability perspective. To this end, the following specific objectives will be addressed:
- Develop a mechanistic model of the solar chloro-photo-Fenton process to predict the removal of micropollutants and the inactivation of indicator microorganisms included in Regulation (EU) 2020/741.
- Evaluate and optimise the continuous flow operation of the solar chloro-photo-Fenton process for wastewater reclamation on a pilot scale.
