Physical–Chemical Wastewater Treatment Technologies

Dear Colleagues,

It is well known that wastewater contains organic and inorganic pollutants, and they may pose hazards to human health and ecosystems. The current action plans regarding the circular economy call for wastewater treatment plants (WWTPs) to be turned into water resource recovery facilities (WRRFs). In this scenario, treatment activities are focused on improving water and sewage sludge quality for recovery opportunities and minimizing environmental damage. Physical–chemical treatments are particularly important to remove water-insoluble substances or colloids. This is achieved through the addition of coagulants and flocculants. Conventional processes are focused on macropollutants including suspended solids, organic carbon, nitrogen, phosphorus and pathogens from wastewater; however, they are not designed to effectively remove micropollutants, such as recalcitrant pharmaceuticals. Finding the proper technology to remove these compounds is still challenging.

In this Special Issue, we invite submissions studying recent advances in the field of physical–chemical treatments for wastewater, including theoretical and experimental analyses, as well as comprehensive review papers. They will undoubtedly contribute to the knowledge and development of the technology. The following topics are proposed, although other related topics are also welcome:

• Development of new physical, chemical and hybrid treatments for wastewater containing micropollutants;
• Improvement of existing methods to achieve higher removal of pollutants;
• Development of cost-effective methods;
• Analysis of emerging micropollutants in wastewater and sewage sludge;
• Fate and transport of pollutants in water and sewage sludge.

We look forward to receiving your contributions.

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.
