Dear Colleagues,

Significant amounts of wastewater have been produced by domestic, industrial, and agricultural sectors driven mainly by the growth of population and industrialization. There are thousands of inorganic, organic, and biological pollutants considered to be contaminants in wastewater and many of them can have serious effects on human health and the environment. Many conventional and non-conventional technologies have been employed to treat different types of wastewater in order to meet the legal requirements for discharge or reuse. The transition to a circular economy requires the use of innovative technologies to treat wastewater streams, minimizing generation of sludge and recovering valuable products. Membrane and adsorptive processes have proven to be promising options to removal of contaminants and/or recover valuable compounds present in wastewaters.

This Special Issue aims to gather high quality research papers and review papers that emphasize the significant importance of separation processes based on adsorption/ion-exchange and membrane technologies in wastewater treatment. It is intended to cover the synthesis of novel adsorbents and membranes, understanding of the mass transport mechanisms, treatment strategies, modeling and simulation studies, design and evaluation of |techno-economic feasibility. Potential topics include, but are not limited to:

• New adsorbents and materials for membrane synthesis for water and wastewater treatment
• Recovery of valuable metals by adsorption and ion-exchange
• Adsorption of organic pollutants
• Integration of membrane processes to recover high-added value compounds from agro-industrial wastewaters
• Membrane processes for wastewater reuse
• Membrane bioreactors technology

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. Water 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 2600 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.
