Recent Advances in Wastewater Treatment and Water Reuse

Dear Colleagues,

Water is the most indispensable commodity in the world. However, the available amount and quality of freshwater is continuously deteriorating due to a combination of natural and anthropogenic factors resulting in the release of contaminated water. Worldwide, wastewater treatment plants (WWTPs) are only permitted to release adequately treated effluents to the environment. However, most plants fail in their mission and release poorly treated effluents. As a result, people living in emerging economies and in the vicinities of sources of pollution are more exposed to these contaminated effluents and bear all the negative consequences.

It is also known that conventional water and wastewater treatment systems were not designed to remove emerging contaminants. The inefficiencies of these systems have resulted in catastrophic environmental and health issues, including organic and inorganic pollution, water-borne diseases, and antimicrobial resistance. Ultimately, this puts a massive strain on drinking water treatment plants, which require additional and advanced treatment technologies to ensure the production of water that meets national and global standards. Therefore, there is a pressing need for the development of treatment tools to address a wide range of conventional and emerging pollutants in both water and wastewater treatment streams. Additionally, a great deal of attention must be focused on the development of complementary and alternative disinfection methods to the traditional disinfectants, such as chlorine gas, to ensure adequate disinfection and minimization or elimination of harmful disinfection byproducts.

Globally, catalytic membrane reactors (CMRs) are promising technologies for achieving green and sustainable chemical engineering practices in water and wastewater treatment. Meanwhile, photocatalytic degradation and membrane separation have emerged as the most promising technologies for removing recalcitrant pollutants such as per- and polyfluoroalkyl substances (PFASs) and pharmaceuticals.

This Special Issue on “Recent Advances in Water and Wastewater Treatment Technologies” seeks high-quality works (research articles, reviews, and short communications) focusing on advanced water treatment technologies, including advanced oxidation processes (AOPs), advanced reduction processes (ARPs), chemical oxidation (ozonation, chlorine dioxide oxidation, chloramination), adsorption, nanotechnology (nanoparticles and nanocomposites), and membrane and hybrid systems that combine two or more techniques. Topics include but are not limited to the treatment of organic contaminants such as PFASs, pharmaceuticals, personal care products, pesticides, and dyes; inorganic contaminants, including heavy metals and nutrients; and disinfection approaches to ensure that treated water meets the requirements for discharge purposes in the environment and/or drinking.

Authors are invited to submit multidisciplinary manuscripts that describe studies of water and wastewater treatment technologies based on chemical processes, environmental processes, catalysis processes, separation processes, and materials processes for consideration in this Special Issue.

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. Processes is an international peer-reviewed open access monthly 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 2400 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.
