Emerging Technologies for Remediation of per- and Polyfluoroalkyl Substances (PFAS) from Contaminated Water

Dear Colleagues,

The continuous expansion of urbanization had led to the accumulation of a myriad of chemicals on surface waters, adversely affecting human life, flora, and fauna. Per- and polyfluoroalkyl substances (PFAS) are a group of environmentally persistent emerging contaminants which have been used in the manufacturing of various consumer products. Drinking water acts as the major source of exposure to these recalcitrant pollutants for humans across the globe. Several regulatory guidelines determining the maximum allowable level of PFASs in drinking water has been declared by various environmental agencies. Conventional water treatment technologies appear to be ineffective for the removal of these contaminants due to their complex nature and lower concentration (several orders of magnitude) compared to other residual contaminants. As the environmental guidelines become more stringent, several promising technologies are being developed to address the complexities of PFASs and co-contaminants in real-world environmental systems. In this regard, this Special Issue aims to outline the latest scientific developments for the removal of PFASs from drinking or surface water with a view towards real-world implementation. Submissions to this Special Issue include, but are not limited to, the following topics: membrane-based removal of PFASs; adsorbents for PFAS removal; biological treatment of PFASs; advanced oxidation approaches for PFAS removal; novel technologies for the treatment of drinking and/or domestic wastewater contaminated with PFASs; techno-economic assessment of various removal technologies; assessing the human health risks of PFASs; mechanistic investigation of the removal of PFASs; theoretical investigation of PFAS removal materials and/or pathways.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. ChemEngineering is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
