Summary: To better safeguard public health and reduce health risks during the bathing season, an effective monitoring and management strategy is required to deal with the threat of toxin-producing cyanobacteria. Molecular tools like qPCR and HTS can be used in early-warning monitoring of European Union bathing water sites and compare the genotypes of cyanobacteria with actual microcystin occurrence. The combination of HTS and qPCR techniques, along with monitoring of environmental parameters, is highly useful in ensuring timely identification of health risks.

Summary: The EU Bathing Water Directive requires member states to assess bathing water quality using faecal indicator bacteria levels. However, this criterion is limited as it does not consider differences in hydrodynamic properties of bathing waters and assumes equal decay of all faecal pathogens. This study simulated sewage discharge events in different aquatic environments and found that faecal indicator decay is important in dispersion and advection/dispersion dominant systems. Including viral indicators could improve water quality modelling and reduce the risk of waterborne illnesses.

Summary: We have quantified the inputs and fate of nutrients in European fresh and marine waters from 1990 to 2018 using the GREEN model. Nutrient inputs in the 1990s and early 2000s decreased significantly, leading to a reduction of nutrient pollution in freshwater and the sea in all regions. However, from around 2008-2010, there has been an increase in nutrient inputs, particularly from agricultural diffuse sources. Sustainable nutrient management on agricultural land is crucial for effective nutrient control in river basins.

Summary: Norovirus infections are a major cause of acute gastroenteritis worldwide and the most frequently reported cause in Germany. The high infectivity and environmental persistence of norovirus make it relevant for water related infections. However, there is a lack of long-term norovirus data, raising questions about the relevance of inter-annual variability for risk management. This study aims to derive risk scenarios for health risk assessment of fieldworkers when treated wastewater is used for irrigation, and highlights the importance of considering the within and between year variability of norovirus concentrations.

Summary: This study investigates the effect of cation exchange resin (CER) on the sequential recovery of hydrogen and methane from anaerobic digestion (AD) and the corresponding mechanisms. The results show that CER can simultaneously enhance the production of hydrogen and methane by promoting the solubilisation, hydrolysis, and acidification of organic matter. Additionally, CER facilitates effective contact between bacteria and organic particulates and reduces the energy barrier for mass transfer during methane production. The study also reveals changes in the microbial community structure and metagenomics during the AD process.

Summary: The fouling of seawater reverse osmosis membranes is a persistent challenge in desalination. This study monitored the operational performance of a desalination plant for 7 years and the fouling development in different areas of membrane modules. The findings showed that operational performance declined over time and fouling mainly occurred at the feed side of the modules, with the highest microbial diversity. Keystone species like Chloroflexi and Planctomycetes played an important role in maintaining community structure and biofilm maturation. Polysaccharides, soluble microbial products, marine humic acid-like substances, and inorganic substances contributed to fouling. Overall, biofouling had a significant impact on membrane fouling after 7 years of operation.

Summary: This study implemented a microaerobic-aerobic configuration in a full-scale municipal wastewater treatment facility and investigated the effects on sludge characteristics, pollutant removal, microbial community, and granulation mechanisms. The results showed successful transition from flocculent-activated sludge to well-defined AGS after two months of operation. The primary pathways for pollutant removal were simultaneous nitrification, denitrification, and phosphorus removal. Moreover, the incorporation of internal separators induced shifts in the flow pattern, which promoted granulation.

Summary: By synergizing organic carbon source, thiosulfate, and zero-valent iron, efficient mixotrophic denitrification of oligotrophic secondary effluent can be achieved. Thiosulfate plays a vital role in promoting TN removal efficiency, while corrosion of Fe0 releases OH- to neutralize H+ from thiosulfate-driven denitrification, creating a suitable environment for denitrification. The coordination of thiosulfate and Fe0 maintains the dominance of Thiobacillus for denitrification.
