Treatment technologies for emerging contaminants in wastewater treatment plants: A review

Prangya R. Rout et al.

Summary: Emerging contaminants (ECs) are unregulated anthropogenic chemicals that persist in the environment and are considered contaminants of emerging environmental concerns. Major classes of ECs include pharmaceuticals and personal care products, surfactants, plasticizers, pesticides, fire retardants, and nanomaterials. In wastewater treatment plants, EC removal efficiency ranges from 20-50% in the primary treatment step, 30-70% in the secondary treatment step, and >90% in the tertiary treatment step.

A review of the biotransformations of priority pharmaceuticals in biological wastewater treatment processes

P. Y. Nguyen et al.

Summary: This review focuses on the biotransformations of key pharmaceutical compounds (PhACs) in biological wastewater treatment plant (WWTP) processes, highlighting their importance in removing PhACs from WWTP effluents. Critically assessing the biodegradation of 7 relevant PhACs on the EU Watch list, the review also discusses the impact of relevant factors on biological WWTP processes. Promising technologies and operational strategies for controlling PhAC releases are emphasized, along with suggestions for future research needs.

Making waves: Improving removal performance of conventional wastewater treatment plants on endocrine disrupting compounds (EDCs): their conjugates matter

Ze-hua Liu et al.

Summary: Endocrine disrupting compounds (EDCs) are emerging contaminants that cannot be effectively removed by traditional wastewater treatment methods. Advanced chemical oxidation methods, such as ozonation, have been proven to be effective but costly in removing EDCs. This study highlights the importance of EDCs conjugates, showing that their concentrations vary with temperature and increasing cleavage rates can improve removal efficiency.

Occurrence and removal of 17α-ethynylestradiol (EE2) in municipal wastewater treatment plants: Current status and challenges

Zhao Tang et al.

Summary: This study critically reviewed the occurrence and removal of 17 alpha-ethynylestradiol (EE2) in municipal wastewater treatment plants (WWTPs). The results showed that the concentration of EE2 in municipal wastewater was generally higher than the reported lowest-observed-effect concentration, indicating an urgent need for EE2 removal in WWTPs.

Spatial variation of pharmaceuticals in the unit processes of full-scale municipal wastewater treatment plants in Korea

Dong-Jin Son et al.

Summary: This study evaluated the spatial variations of fifteen pharmaceuticals in the unit processes of four full-scale municipal WWTPs by analyzing solid and liquid samples. Different pathways for pharmaceutical removal were investigated, with acetaminophen and caffeine showing a significant decrease in mass loading in the biological treatment process, while ibuprofen exhibited a temporary increase possibly due to deconjugation. Adsorption by biosolids was the major removal mechanism for selected antibiotics in WWTPs. The use of a membrane bioreactor (MBR) was found to be effective in reducing pharmaceuticals in municipal wastewater due to its high concentration of biosolids acting as adsorbents.

Hiba ZIND et al.

Summary: This study investigated the contamination of pharmaceutical metabolites and transformation products in ten sites along three French rivers, revealing their presence in various compartments at different concentrations. QSAR models were used to predict the ecotoxicity of the studied compounds, showing that some metabolites and TPs may be more toxic than others.

A critical review on the distribution and ecological risk assessment of steroid hormones in the environment in China

Ruyue Zhong et al.

Summary: This study summarizes the current contamination status of steroid hormones in different environmental compartments in China and preliminarily assesses the associated risks to ecological systems. The results show that steroid hormones are ubiquitously present in Chinese surface waters. The median risk quotients of most steroid hormones in surface waters and sediments are lower than 1, indicating low to moderate risks to local organisms.
