“…A few review articles have concentrated on strategies for removing PFAS compounds from water, including sorption on various adsorbents (Du et al, 2014;Zhang et al, 2019;Vo et al, 2020), focussing on field testing of selected adsorbents (Espana et al, 2015), and advanced defluorination and degradation (thermal and non-thermal) methods (Ahmed et al, 2020;Vo et al, 2020), but review articles critically analysing soil PFAS remediation are scarce in the literature. Only two reviews have been written on this topic in the recent past (Ross et al, 2018;Mahinroosta and Senevirathna, 2020).…”

“…In wastewater, it was found that PFASs could be biodegraded under aerobic or anaerobic conditions, but various persistent intermediates such as perfluorinated carboxylic acids (PFCAs) are generated from the degradation (Phong Vo et al, 2020; Wang et al, 2005; Zhang et al, 2013). This means that only biotransformation rather than complete mineralization occurs during the biodegradation of PFASs.…”

“…This means that only biotransformation rather than complete mineralization occurs during the biodegradation of PFASs. Although the bacterial strains that can degrade PFASs have been found, they are not kinetically effective and prolonged biodegradation could still be a problem for practical applications (Phong Vo et al, 2020). At the moment, enhancing the PFAS removal efficiency by BAC process might be conducted by improving the adsorption process or combining with other treatment processes such as AOPs (Glover et al, 2018).…”

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.…”
