“…This issue is not limited to APIs but apply also to other compounds, such as for example plastic additives that are present on plastic food and drinking containers. For example, Bisphenol A (BPA) despite being worldwide banned on children food containers is present in a large range of plastic containers exposing humans to their ingestion regularly, being one of the MPs most commonly detected in wastewater streams …”

Among other measures to mitigate the environmental impact of APIs in water, cutting edge, highly efficient, low-energy technologies need to be introduced in urban WWTP.…”

Nowadays, the scarcity of clean fresh water is a major concern to public health. One of the main issues linked with this topic is the unavoidable contamination of water bodies with active pharmaceutical ingredients, which results from production and metabolization of prescribed and over the counter drugs closely related to human health and wellbeing. As the currently available techniques for removal of micropollutants (MPs) from wastewater are not sufficiently broad, efficient, and cost effective, new sustainable alternatives are required to prevent the contamination of water bodies which can compromise the viability of aquatic ecosystems and, ultimately, life on earth as we know it. Herein, a natural eutectic solvent (ES), based on fatty acids, is proposed to remove important MPs, sodium diclofenac, the most used nonsteroid anti-inflammatory drug, and a plasticizer, Bisphenol A (BPA), through liquid−liquid extraction (LLE), as well as preparation of liquid membranes. The extraction of sodium diclofenac through LLE reached an efficiency of (97 ± 1)% that was maintained when shifting to the liquid membranes while reducing the quantity of solvent to only 1.5% of that required in LLE. These membranes were reused through 10 cycles of extraction without major loss of efficiency. The optimal extraction efficiency of BPA using ES supported in membranes reached (63 ± 1)%. The easy preparation of hydrophobic natural eutectic solvents-based absorbent materials through their impregnation in porous inert supports enables the development of highly efficient and costeffective adsorption technology for the removal MPs from water.

“…BPA is the most important bisphenol compound detected in wastewater treatment plants (WWTPs) [11]. However, due to the limitations of currently available treatment processes, WWTPs have become the main source of BPA and bisphenol analogs in surface water [12]. In addition, beverage bottles, food packaging bags, and plastic landfill leachate have also become major routes through which BPA enters the environment [13].…”

This study assessed the toxic effects of bisphenol A (BPA) on the microbial community and the function of activated sludge in sequencing batch reactors (SBRs). The toxicity of BPA was mitigated through dosing sludge with Rhodococcus Req-001. BPA reduced the biomass of sludge, and the proportion of viable bacteria decreased with the aggravation of BPA pollution. BPA affected the secretion of extracellular polymeric substances (EPSs), increased the ratio of polysaccharide to protein, and deteriorated the sedimentation performance of sludge. BPA decreased the abundances of functional bacteria involved in the degradation of organic matter and water purification, including Polaromonas, Dechloromonas, and Nitrospira, and the water purification capacity of the reactor decreased. Req-001 enhanced the BPA removal efficiency by 15%, and increased ammonia nitrogen and phosphorus removal by 8.8% and 22.7%, respectively. The functional recovery ability of the sludge system and the high removal ability of Req-001 make it a promising specie for use in BPA bioremediation. This study combined the effect of BPA on activated sludge and reactor performance with the microbial community, clarified the toxic mechanism of BPA on activated sludge, and therefore provides a theoretical basis and potential solutions to help WWTPs cope with the toxic effects of BPA.
