Advanced Biological Wastewater Treatment and Nutrient Removal

Dear Colleagues,

The traditional activated sludge process, developed over more than 100 years ago, has become the most widely adopted biological treatment technology in wastewater treatment plants worldwide. However, with the continuous increase in wastewater production and the tightening of discharge standards, the traditional biological treatment process faces several challenges, including low treatment efficiency, high energy consumption, and low volumetric load. These limitations make it difficult to meet the new demands for efficient and low-energy wastewater treatment under carbon-neutral targets. In recent years, innovations in wastewater biological treatment theories have driven technological advancements and attracted widespread attention from researchers.

This Special Issue mainly focuses on cutting-edge research and technological applications related to advanced wastewater biological treatment and nutrient removal. For this Special Issue, we invite the submission of original research papers or review papers. The topics include, but are not limited to, the following:

1. New principles and metabolic pathways for biological nitrogen and phosphorus removal from wastewater;
2. Stable operation and optimization strategies for the anammox process;
3. Applications and regulation of aerobic granular sludge technology;
4. New biofilm technologies based on functional carriers;
5. Engineering applications of new technologies for nitrogen and phosphorus removal from wastewater.

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.
