Biological Wastewater Treatment Process and Nutrient Recovery

Dear Colleagues,

The biochemical wastewater treatment process has huge advantages, such as high efficiency, less energy consumption, simple operation and less investment, which can meet the requirements of modern urban sewage treatment. The biological wastewater treatment process is mainly a method involving the use of microbial metabolism to remove organic and nutrient pollutants in wastewater under aerobic or anaerobic conditions. For now, many novel processes focusing on anaerobic ammonia oxidation (anammox), complete ammonia oxidation (comammox), partial nitrification, partial denitrification, enhanced biological phosphorus removal (EBPR), denitrifying phosphorus removal (DPR), endogenous denitrification, denitrifying anaerobic methane oxidation (DAMO), etc., have attracted much more attention.  However, regarding the use of biological wastewater treatment processes, there is still a great need to continue to strengthen the research and innovation of the processes to further improve the carbon and nutrient removal efficiencies, and thus to contribute to the sustainable development of urban water resources. Moreover, many components can be recovered during the treatment process and from residuals from wastewater treatment, such as carbons, nutrients, metals and biodegradable plastic. New trends and technological innovations still need to be developed for the full-scale implementation and use of biological wastewater treatment.

In order to trace the research progress of biological wastewater treatment processes and nutrient recovery technologies, a Special Issue will be organized by Water. This Special Issue focuses on original articles or review articles related to biological wastewater treatment processes and nutrient recovery, including but not limited to the following:

• Energy saving wastewater autotrophic/heterotrophic nitrogen removal processes, such as anammox, comammox, partial denitrification and nitritation;
• Enhanced phosphorus removal from wastewater;
• Development and utilization of carbon sources in sewage/sludge, such as anaerobic fermentation, VFAs and methane utilization;
• Greenhouse gas emissions;
• Biological treatment of emerging pollutants;
• Biological processes involved in the removal of toxic pollutants;
• Biochemical treatment technology of odorous gas during wastewater treatment processes;
• Carbon, nitrogen and phosphorus recovery and reuse technologies;
• Other related topics

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-anonymized 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.
