Summary: Municipal wastewater treatment plants contain contaminants that may impact the composition of beneficial bacterial communities associated with aquatic organisms. This study found that the microbiomes of invertebrates collected downstream of WWTPs differed from those collected upstream, which could have implications for host health and the transport of WWTP-derived bacteria in aquatic ecosystems.

Summary: This study focuses on organic micropollutants in secondary effluents from municipal wastewater treatment plants, identifying various micropollutants and evaluating an advanced treatment process for their removal. It was found that a combination of ozonation, ceramic membrane filtration, and biological active carbon filtration achieved remarkable removal efficiencies of pharmaceuticals, personal care products, endocrine disrupting chemicals, and odorous compounds in the effluents.

Summary: The effluents from wastewater treatment plants can negatively affect the gut microbiome of downstream organisms, as shown in this study on flutedshell mussels. The composition and diversity of the mussel gut microbiome differed between upstream and downstream sites of the wastewater treatment plants, indicating potential health risks for the host organisms and the transport of wastewater-derived bacteria in aquatic ecosystems.

Summary: High-rate algal ponds (HRAP) are an alternative method for wastewater treatment that can contribute to the circular economy by valorising reclaimed water and algal biomass. Studies show that HRAPs have good removal efficiency for nutrients and contaminants, but further research is needed to understand the risks and requirements of safe wastewater and biomass reuse.

Summary: This study aims to optimize the photocatalytic proxone process using a synthesized ZnO-Fe3O4 nanocatalyst for petroleum wastewater treatment. The results showed that the removal efficiency of COD was 85.3%, while BOD5 and TPH had removal efficiencies of 91.1% and 89.7%, respectively. Therefore, the photocatalytic proxone process has the potential to treat petroleum wastewater.

Summary: The study found that the microbiome of fish gut content was altered downstream of WWTP effluent outfalls, potentially leading to negative health outcomes. Fish collected at different sites had distinct bacterial communities, with upstream samples dominant in Proteobacteria and Firmicutes, and downstream samples increasingly abundant in Proteobacteria and Cyanobacteria.

Summary: The pollution of water bodies worldwide by contaminants of emerging concern is creating challenges for conventional wastewater treatment facilities, with African countries facing more severe problems due to poor sanitation systems and shortage of wastewater treatment plants. African researchers are working on developing and optimizing sampling and analytical procedures, risk assessment models, and efficient remediation technologies to address these environmental threats.

Summary: This study investigated the fate of lanthanides in different wastewater treatment processes, and differentiated the origin of gadolinium (Gd) between medical application and geological background using a normalization approach. The results showed that the removal efficiency of lanthanides decreased with their atomic number, and the process using alum as a flocculating agent had the highest removal efficiency.

Summary: This paper provides an in-depth analysis of the impact of wastewater treatment plant contaminants on fish liver structure, physiology, and metabolism. It also examines the role of fish liver enzymes and antioxidants in metabolizing xenobiotic compounds and combating oxidative damage. The vulnerability of fish to xenobiotic compounds and the importance of biomonitoring exposed fish are highlighted.

Summary: This study provides quantitative data on the occurrence and fate of various emerging contaminants in Indonesia's largest wastewater treatment plant. The study highlights the efficiency of waste stabilization ponds in removing biodegradable contaminants, while also identifying poor removal efficiency for some persistent contaminants. The findings emphasize the importance of conventional wastewater treatment plants in reducing the concentrations of contaminants to minimize aquatic contamination risk.

Summary: The presence of pharmaceutical products in municipal wastewaters has become a major environmental concern. This study focuses on the application of ozonation to degrade benzodiazepine drugs in the effluents of two wastewater treatment plants in Rio de Janeiro. Through optimization of operating conditions, significant removal of these drugs was achieved, especially when using a larger effluent volume and appropriate ozone dose.

Summary: Forward osmosis (FO) is an innovative approach that plays a crucial role in addressing water scarcity and contamination issues. FO membranes offer an efficient solution for wastewater treatment and removal of contaminants. However, factors such as concentration polarization, membrane fouling, draw solute selection, and reverse salt flux can significantly impact the performance and efficiency of the FO process.

Summary: This study provides a comprehensive summary of wastewater treatment and emerging contaminants research from 1998 to 2021 using bibliometric analysis. The analysis reveals that China has the highest number of publications and the closest cooperation with the United States. The most cited papers indicate that purification or removal techniques such as ozonation or membrane filtration can effectively remove pharmaceutical compounds from the water environment. Efficient detection of emerging contaminants and optimization of removal methods are identified as current challenges.
