“…36,49,77], the CSO pollutant loads are comparable, in magnitude, to the emission of wastewater treatment plants (considering an annual basis). Thus, since CSO events have low occurrence frequency, this means that they release large volumes of water with a remarkable concentration of pollutants in terms of carbon, nutrients, micropollutants, heavy metals and pathogens [49,71,77].…”

Evaluating longitudinal dispersion of scalars in rural channels of agro-urban environments

In agro-urban environments, the water resource conveyed by rural channels is susceptible to a gradual impoverishment due to the continuous combined sewer overflow release, constituting a pending and urgent issue for water management companies and the entire community. Reliable one-dimensional longitudinal dispersion coefficients D are required to model and study the hydrodynamics and water quality patterns at the scale of rural channel networks. Empirical formulas are usually adopted to estimate D but the accuracy in the prediction could be questionable. In order to identify which are the most suitable formulas to determine D in rural channels, field tracer measurements were carried out in three rural channels with typical geometry and configuration. The obtained D values were then compared with the most commonly used predicting formulas that the literature provides. The accuracy of the predictors was further checked by simulating different flow rates inside the tested channels by using a one-dimensional hydraulic model. Starting from the obtained results, indications and guidelines to choose the most suitable formulas to predict D in rural channels were provided. These indications should be followed when developing realistic quality models in the agro-urban environments, especially in those cases where direct measurements of the longitudinal dispersion coefficient D are not available.

“…The discharge of antibiotics, (multi-)resistant bacteria and their respective resistance genes to the aquatic environment further worsens this threat, as selective pressure on bacteria and horizontal gene transfer promote the formation of antimicrobial resistances in the environment (Adler et al 2018;Abe et al 2020). A significant advantage of on-site treatment at hospitals is the reduction of released bacteria and antimicrobial resistance genes to the environment by combined sewer overflows (CSO) (Verlicchi 2018), which represent a major pathway of pathogens into the aquatic environment (Schreiber et al 2016).…”

Dissemination of multiresistant bacteria and high concentrations of micropollutants by hospitals and other medical facilities can be significantly reduced by a wide variety of on-site treatment approaches. Membrane filtration technologies, ranging from microfiltration to reverse osmosis, have been adapted in many studies and offer multiple purposes in advanced wastewater treatment configurations. While the direct rejection of pharmaceutical compounds and pathogens can only be achieved with nanofiltration and reverse osmosis processes, porous membranes are known for their pathogen removal capabilities and can be used in combination with other advanced treatment approaches, such as oxidation and adsorption processes. This review was conducted to systematically assess studies with membrane filtration technologies that are used as either stand-alone or hybrid systems for the treatment of hospital wastewater. In this review, four different databases were screened with a pre-set of search strings to thoroughly investigate the application of membrane filtration technology in hospital wastewater treatment. Hybrid systems that combine multiple treatment technologies seem to be the most promising way of consistently removing micropollutants and pathogens from hospital wastewater, but additional economic assessments are needed for an extensive evaluation.

“…The main entry pathways of microorganisms, with ARG and trace pollutants, into the environment, are the effluents of munic ipal sewage treatment plants (STP) (Müller et al, 2018;Stange et al, 2019;Watkinson et al, 2009), and in the case of heavy rain fall events, the combined sewer overflow discharges (Christoffels et al, 2014;Schreiber et al, 2016), and the run off from manured fields (Christian et al, 2003;Schmithausen et al, 2018;Schreiber et al, 2015). Antibiotics will pass treated organisms unchanged or will be excreted as metabolites or conjugates (Kümmerer, 2009).…”
