Potential of decentralized wastewater treatment for preventing the spread of antibiotic resistance, organic micropollutants, pathogens and viruses (PRESAGE)

New approaches are needed to reduce the emission of contaminants of emerging concern (CECs). Some sources contribute strongly to suchemissions, which has driven the focus of PRESAGE on innovative decentralized wastewater treatment (WWT), based on anaerobic andaerobic compact systems.
Ongoing project

An integrated analysis of the behaviour of organic micropollutants (OMPs), antibiotic resistant microorganisms and genes (ARMs/ARGs) and pathogens (viruses and bacteria) will be carried out. This will allow better understanding the relation betweenthe operational parameters of reactors, the microbiological evolution in the system, the removal of OMPs and pathogens, and thedevelopment of ARMs and ARGs. The contribution of such a complex mixture on the final effluent ecotoxicity will be assessed.The technologies will be validated at 4 demosites treating black and grey water, and effluents from hospitals and an antibiotic industry, inclose collaboration with the industrial sector. This high readiness level anticipates a good impact of project results on wastewater innovation. Experts in the field of advanced WWT, microbiology and ecotoxicology will strongly cooperate and participate in a mobility plan focusing oncomplementary skills.

PRESAGE impacts society and economy, boosting the water industry and protecting the environment from effluent discharges containing CECs. In the proposed treatment strategy a minimum global impact is targeted, preferentially promoting the onsite water reuse.
