Since the acceptable PFAS levels in drinking water vary among regulatory agencies, treatment plants (DWTPs) are urged to adapt their processes improve removal. This study's objective was assess performance of powdered and granular activated carbon (PAC GAC) for removal evaluate applications DWTPs. Raw filtered waters were used examine different types PAC GAC batch rapid small-scale column tests, respectively. A conventional dose (10 mg/L) eliminated 40% total PFAS76 25% long-chain after 10 min. It would, however, transfer 24 ppb daily biosolids. comparable (equivalent 27,000 BV) removed 43% 80% PFAS. Considering a medium-sized DWTP with target 80%, pretreatment would require an elevated AC 29 mg/L. will incur equivalent cost post-treatment six columns, while remarkably increasing mass dry sludge by 46%. Hence, emerges as better suited instant intervention mitigate contaminations without revoking need long-term solution.

Per- and polyfluorinated alkyl substances (PFAS) have long been known for their detrimental effects on the ecosystems living organisms; however long-term impact marine environment is still insufficiently recognized. Based PFAS persistence bioaccumulation in complex food network, adverse will be exacerbated by global processes such as climate change synergies with other pollutants, like microplastics. The range of fluorochemicals currently included umbrella has significantly expanded due to updated OECD definition, raising new concerns about poorly understood dynamics negative ocean wildlife human health. Mitigation challenges approaches, including biodegradation studied materials environmental removal are proposed here, highlighting importance ongoing monitoring bridging research gaps. EU regulations, good practices legal frameworks discussed, emphasis recommendations improving ecosystem management.

Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals characterized with persistence multisurface resistance. Their accumulation in the environment toxicity to human beings have contributed rapid development regulations worldwide since 2002. The sorption strategy, taking advantage intermolecular interactions for PFAS capture, provides promising efficient solution treatment contaminated sources. Hydrophobic electrostatic two commonly found commercially available sorbents, fluorous interaction being novel mechanism applied sorbent selectivity. main object this Perspective is provide critical review on current design criteria particular focus their mechanisms as well limitations. An outlook future innovative sorbents also provided.
