“…The digestate of AD-treated black wastewater also contains emerging contaminants, such as pharmaceuticals, perfluoroalkyl substances (PFAS), hormones, and personal care products. ,− These contaminants can harm environmental and human health by bioaccumulating in soils, organisms, and crops. Reusing AD digestate in agriculture can pose public health risks through possible bioaccumulation of residues up the food chain.…”

Successfully addressing the complex global sanitation problem is a massive undertaking. Anaerobic digestion (AD), coupled with post-treatment, has been identified as a promising technology to contribute to meeting this goal. It offers multiple benefits to the end users, such as the potential inactivation of pathogenic microorganisms in waste and the recovery of resources, including renewable energy and nutrients. This feature article provides an overview of the most frequently applied AD systems for decentralized communities and low-and lower-middleincome countries with an emphasis on sanitation, including technologies for which pathogen inactivation was considered during the design. Challenges to AD use are then identified, such as experience, economics, knowledge/training of personnel and users, and stakeholder analysis. Finally, accelerators for AD implementation are noted, such as the inclusion of field studies in academic journals, analysis of emerging contaminants, the use of sanitation toolboxes and life cycle assessment in design, incorporation of artificial intelligence in monitoring, and expansion of undergraduate and graduate curricula focused on Water, Sanitation, and Hygiene (WASH).

“…decentralized wastewater sanitation systems that treat black water and grey water (Figure 1.1). For example, black water is treated by anaerobic digestion, and showed poor removal of OMPs, such as diclofenac and carbamazepine (Kujawa-Roeleveld et al, 2008;Moerland et al, 2022). Diffuse and other sources of water with OMPs originate from industry, livestock, agriculture, and surface run-off (Kosek et al, 2020).…”

Microalgae-based technology for wastewater treatment: exploring organic micropollutants removal

View full text Add to dashboard Cite

Organic micropollutants (OMPs) need to be removed from wastewater as they can negatively affect aquatic organisms. It has been demonstrated that microalgae-based technologies are efficient in removing OMPs from wastewater. In this study, the removal processes and kinetics of six persistent OMPs (diclofenac, clarithromycin, benzotriazole, metoprolol, carbamazepine and mecoprop) were studied during cultivation of Scenedesmus obliquus in batch mode. These OMPs were added as individual compounds and in a mixture. The short experiments (8 days) were designed to avoid masking of OMPs removal processes by light and nutrient limitation. The results show that diclofenac, clarithromycin, and benzotriazole were mainly removed by photodegradation (diclofenac), biodegradation (benzotriazole), or a combination of the two processes (clarithromycin). Peroxidase was involved in intracellular and extracellular biodegradation when benzotriazole was present as individual compound. Carbamazepine, metoprolol and mecoprop showed no significant biodegradation or photodegradation, and neglectable removal (<5%) by bioadsorption and bioaccumulation. The mixture of OMPs had an adverse effect on the photodegradation of clarithromycin and diclofenac, with reduced first-order kinetic constants compared to the individual compounds. Benzotriazole biodegradation was inhibited by the presence of the mixture of OMPs. This indicates that the presence of the OMPs inhibits the photodegradation and biodegradation of some individual OMPs. These results will improve our understanding on the removal processes of individual and mixtures of OMPs by microalgae-based technologies for wastewater treatment.
