Summary
The main scope of this project proposal is to develop new technologies for the removal of legacy and emerging contaminants (organochlorine insecticides, brominated flame retardants) from wastewater and contaminated groundwater using advanced oxidation processes (AOPs), iron-based nanoparticles (FeS and Fe0) and anaerobic biodegradation processes. The anaerobic biodegradation, but especially the advanced oxidation processes (AOPs) are very useful techniques in removal of the above-mentioned pollutants from wastewater since, comparing with other treatments techniques, both techniques could effectively eliminate organic compounds in aqueous phase, rather than collecting or transferring pollutants into another phase. A sono-photo-reactor (see figure 1) will be setup up to perform the sono-photo-Fenton processes of the key target organic contaminants compounds (HCHs, PBDE-209, HBCDs, and HCDBCO) as a laboratory technology for the treatment of wastewater and a bioreactor will be setup up to develop advanced laboratory technologies for the biodegradation of the key target compounds. Therefore, this project is aiming to upgrade an experimental laboratory demonstrator (TRL 3) to a laboratory validated technology (TLR4) by validating both the sono-photo-reactor and bioreactor technologies.

Objectives
The project objectives are:
O1. New methodologies for AOPs (photo-Fenton and Son-Fento using new metal catalysts (i.e. Cu), for the advanced treatment of wastewater.
O2. Degradation pathways of target compounds (HCHs, PBDE-209, HBCDs, and HCDBCO) under oxidative conditions (photo-Fenton, sono-Fenton) and reductive conditions (reduction with Fe0 and FeS nanoparticles)
O3. Investigation of biodegradation of FRs (PBDE-209, HBCDs, and HCDBCO).
O4. Setup of a sono-photo reactor (as lab scale experimental model) to perform the sono-Photo-Fenton process of the key target organic contaminants compounds (HCHs, PBDE-209, HBCDs, and HCDBCO) as a laboratory technology for the advanced treatment of wastewater.
O5. Setup up of a bioreactor to perform advanced laboratory technologies for the biodegradation of the key target compounds (HCHs, PBDE-209, HBCDs, and HCDBCO).
The implementation of this project will lead to the following main expected results:
-Establishing new AOPs methodologies and technologies (photo-Fenton and sono-Fenton using new metal catalysts (i.e. Cu), for the advanced treatment of wastewater.
– Design of a sono-photo reactor (as lab scale experimental model) to perform the sono-photo-Fenton processes of the key target organic contaminants, as a laboratory technology for the advanced treatment of wastewater.
-Development of biotechnologies (using a bioreactor) for the target contaminants, which may lead to the development of cheap bioremediation techniques to be applied at industrial sites.
