Water Purification Processes: Principles, Methods and Applications

Dear Colleagues,

One of the major challenges in the world is to provide clean water and sanitation for all. The declining water quality has a direct negative impact on human health and other biological populations. The key to properly addressing the issues of water pollution and water scarcity is to treat and recycle wastewater (and recover resources). Currently, there has been substantial improvement in the design and operation of water and wastewater treatment systems. Although these treatment-technologies have proven to be reliable to treat water and wastewater containing a complex mixture of pollutants, the development and application of innovative hybrid processes and concepts are still needed in order to meet increasingly stringent control regulations. Also, emerging/persisting contaminants (e.g., PFAS and microplastics) and antimicrobial resistant bacteria have recently been found in various water sources, while the conventional technologies are not designed to remove these pollutants. Thus, researchers have also focused on developing hybrid eco-technologies that combine the operational advantages of advanced technologies or physico-chemical treatment systems and conventional biotechnologies in order to better remove these pollutants.

The objective of this Special Issue is to provide a platform for researchers to report new advances in treatment technologies for water purification, disinfection, desalination, and wastewater reuse, etc. Both original research and review articles are welcome.

Potential topics include but are not limited to the following:

• Wastewater reuse
• Water purification, disinfection and desalination
• Pollutant degradation and resourcization
• Risk assessment and removal of emerging/persisting contaminants
• Greenhouse gas and odor emission during water treatment
• Life cycle assessment of water treatment technologies
• Emerging methods of biological and electrochemical water treatments
• New materials for water treatment
• Innovative hybrid wastewater treatment technologies
• Advances and challenges toward sustainable water treatment

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.
