“…Indeed, according to Arnold et al (2013), water treatment technologies involving clarification, chlorination and activated carbon usually remove between 76 and 99% of bisphenol A present in RW. In another study, conventional DW treatment processes achieved low removal efficiencies for pharmaceutical products such as antibiotics and beta-blockers (Kim et al, 2020), while advanced treatment processes provided higher removal efficiencies (Yang et al, 2017).…”

“…Hence, the quantitative investigation of micropollutants in water sources and DW constitutes a fundamental aspect for the understanding of the existing gaps regarding the possible effects of these substances on biota and human health. In the literature, there have been reported more studies on WWTPs than on WTPs, and often pharmaceuticals removal processes were conducted in laboratory experiments (Yang et al, 2017;Kim et al, 2020). Furthermore, studies considering the temporal variability of micropollutants in supply sources are infrequent (Paíga et al, 2016;Hu et al, 2017;Burns et al, 2018;Santos et al, 2020).…”

The concentrations of 25 pharmaceuticals and endocrine disruptors were monitored in the water coming from the Tibagi River (State of Paraná, Brazil) and in a conventional water treatment plant over 13 sampling campaigns. In raw water, only 3 compounds (bisphenol A, dexamethasone and losartan) were detected with high frequency (>75%) and 4 drugs (estradiol, diclofenac, loratadine and naproxen) were found with moderate frequency (between 30 and 70%). In addition, 7 micropollutants (paracetamol, ethinylestradiol, caffeine, propanolol, diltiazem, benzafibrate and promethazine) were not detected in any of the samples analyzed and 11 other compounds were quantified at low frequency (up to 25%). The conventional treatment process employed at WTP- Jataizinho has proven to be very efficient in removing dexamethasone (∼99%), moderately efficient in reducing bisphenol A (∼47%) concentration and inefficient in removing losartan (∼22%) and loratadine (not removed). The greatest removals were observed during the water clarification stage using aluminum sulfate as coagulant. In general, the dry and rainy seasons did not influence the concentrations of pharmaceuticals and endocrine disruptors in raw water. In terms of the 5 most prevalent micropollutants in treated water (bisphenol A, losartan, dexamethasone, loratadine and naproxen), the human health risk associated with ingesting contaminated water was assessed and considered negligible.

“…Potential biotransformation of PFASs to shorter chain products needs to be optimized based on relative toxicity and effectiveness of downstream treatment. For example, GAC, which can be used after BAC to further remove emerging contaminants including PFASs, is known to be much more effective against long‐chain PFASs than short‐chain ones (Bertanza et al, 2020; Kim et al, 2020).…”

This review article discusses the current state of knowledge on water treatment and reuse by biofiltration systems focusing on biologically enhanced activated carbon (BAC) process. First, the applications of BAC in water treatment systems are overviewed, and then, the mechanisms for both biofilm formation and contaminant treatment are discussed along with the operational parameters influencing the performance of BAC process. Since contaminant removal by BAC is governed by adsorption and biodegradation, both processes are reviewed in relation to the treatment mechanisms. Information on removal of recent emerging contaminants including nitrogenous and unregulated disinfection by-products (DBPs) and their precursors, poly-and perfluorofluoroalkyl substances, nanoparticles, and plasticizers and microplastics by BAC is given along with suggestions for treatment improvements and future research. The uniqueness of this review includes insights on relevant biofilm aspects and the coverage on the abilities of BAC for treatment of recent and less common emerging contaminants especially unregulated DBPs and their precursors, nanoparticles, and plasticizers and microplastics. For future BAC studies, recommendations are proposed on exploring the biofilm development on media and recent emerging contaminants as co-contaminants, as well as developing novel supporting materials such as biochar. © 2020 Water Environment Federation • Practitioner points• The amount and the physiology and physical structure of biofilm affect the treatment efficiency of biological activated carbon. • Biological activated carbon is capable of removing a majority of nitrogenous and unregulated disinfection by-products. • Whether and how biological activated carbon is impacted by and/or can remove nanoparticles, and plasticizers and microplastics remain largely unknown. • Future work on biological activated carbon should focus on biofilm evolution and control, and novel support materials.

“…Per-and polyfluoroalkyl substances (PFAS) present a unique challenge in water and wastewater treatment (Vo et al 2020). Conventional physicochemical and biological treatment methods cannot fully degrade or mineralize PFASs in drinking water treatment (Belkouteb et al 2020;Kim et al 2020;Boone et al 2019;Dauchy 2019;Page et al 2019;Vughs et al 2019;Hopkins et al 2018) or wastewater treatment (Chen et al 2018;Szabo et al 2018;Arvaniti and Stasinakis 2015) and may generate PFAS transformation products. The treatment goal of mineralization relative to PFAS is defined by Horst et al (2020) as complete defluorination regardless of whether the carbon is fully oxidized to carbon dioxide.…”
