Sustainable Wastewater Management in the Context of Circular Economy

Dear Colleagues,

When considering integrative environmental pollution prevention and control, the best options for wastewater management must be linked to the circular economy concept, which transform the wastewater from waste streams (effluents and sludge) into valuable resources. Moreover, urban wastewater treatment plants should be considered as important representatives of the circular economy through the integration of energy generation and resource recovery. The resources from municipal/industrial wastewater plants are recovered in the form of wastewater that might be recycled or reused, or energy, nutrients and other resources that require adequate strategies and treatment processes, which assure not only sustainable wastewater management but also the removal of emerging or priority pollutants. Wastewater recycling and reuse as well as sludge treatment requires advanced and innovative processes (such as membranes, advanced oxidation, biological, sorption, disinfection, etc.) which should be integrated with conventional treatment or developed as separate modules such that the wastewater treatment plants become more financially and environmentally sustainable. Several tools and indicators for the sustainability assessment of wastewater and sludge treatment should be applied, e.g., life cycle assessment, carbon footprint assessment, integrated assessments and more. The research in the field of wastewater management is continuously growing with the development of innovative and emerging technologies and solutions according to circular economy principles.

Potential topics of research or review articles may include but are not limited to the following:

• municipal or industrial wastewater treatment processes such as membranes, advanced oxidation, biological, sorption, etc.;
• assessment of wastewater treatment plants or processes considering the circular economy concepts and sustainability instruments;
• conception of technological processes applied to wastewater treatment recycling and reuse, nutrient recovery;
• integration of advanced processes within the conventional technological flow of wastewater treatment;
• sludge management and valorization

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 250 words) can be sent to the Editorial Office for assessment.

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.
