Advances in Water and Wastewater Treatment Processes

Dear Colleagues,

Although the science of water and wastewater engineering is old, it is a field with continuous development and innovation. Established technologies are optimized in terms of performance, environmental footprint, energy demand, and area requirements, while new and alternative technological solutions are today available. The world of water and wastewater engineering offers today many diverse tools applicable to different economic, climatic, and social contexts. Therefore, it is important to further understand and increase our knowledge on the status and developments of the various wastewater treatment technologies and processes. This Special Issue will cover the most recent progress and developments in the wide range of the treatment technologies to provide the state-of-the-art knowledge for the removal of pollutant from water and wastewater.

Contributions are accepted from both research and the industry as well as experiences from full-scale applications and case studies. Review papers summarizing the existing knowledge and technological status of different technologies and processes are also welcome. The potential technologies include but are not limited to:

• Activated sludge and its variants
• Extended aeration
• Membrane filtration and bioreactors
• Sequencing batch reactors
• Attached growth biofilm reactors
• Moving bed biofilm reactors
• Aerobic / anaerobic systems
• Nature-based solutions such as constructed wetlands, stabilization ponds, etc.
• Trickling filters
• Upflow anaerobic sludge blanket reactors
• Chemical treatment
• Microbial fuel cells
• Filtration with eg activated carbon, natural rocks, synthetic media, etc.
• Dissolved air flotation
• Coagulation, flocculation, adsorption, ion exchange
• Advanced oxidation processes such as ozonation, photocatalysis, UV radiation, hydrogen peroxide oxidation, etc.
• Waste sludge minimization and stabilization
• Materials and nutrient recovery
• Mathematical simulation methods

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.
