Abstract
The inappropriate disposal of organic pollutants has been drawing attention from the research community in recent years. One of its consequences is the rise of the emerging contaminants (ECs): a vast array of synthetic products that have the general characteristics of being bioacummulative, not regulated and potentially lead to antimicrobial resistance when found in wastewater. In general, emerging contaminants are endocrine disrupters and include pharmaceuticals and personal care products (PPCPs), artificial sweeteners, hormones, pesticides, illicit drugs, among others. A feasible technique to treat the wastewater contaminated with ECs is the photodynamic inactivation (PDI), which consists in the interaction between a photosensitizer (PS) with a light source of a specific wavelength in order to yield reactive oxygen species (ROS) which in turn will break the molecules of the contaminants. This work is aimed at carrying out laboratory tests with Escherichia coli, a bacterium responsible for various diseases, which will guide the setup definition for the development of prototype treatment units. They are to operate under optimal conditions for the inactivation of selected microorganisms and ECs. The significance of the flow conditions, light irradiance, and PS concentration are on the scope of the future designed experiments.
