Special Issue Information
Dear Colleagues,
Emerging contaminants (ECs)—such as pharmaceuticals, personal care products, microplastics, endocrine-disrupting compounds, PFAS, and some industrial chemicals—pose a growing threat to aquatic ecosystems and public health due to their persistence and bioactivity, even at trace concentrations. Conventional wastewater treatment processes often fail to effectively remove these micropollutants, underscoring the need for innovative solutions. This Special Issue focuses on recent advances in technologies for the efficient removal of ECs, with an emphasis on innovative, sustainable, and cost-effective solutions.
We welcome contributions that explore novel biotechnological solutions, such as microbial consortia, enzymatic pathways, constructed wetlands, and biofilm-based systems designed to enhance the removal of ECs from wastewater. Emphasis is placed on enhancing treatment efficiency and practical applicability, understanding the removal mechanisms, and deciphering transformation products and their toxicity. Studies involving multitrophic levels or sequential biological processes, which provide insight into synergistic effects, are of particular interest.
New research papers, reviews, and case reports demonstrating novel biological approaches to remove ECs from wastewater from various sources are welcomed.
This collection aims to provide an overview of current trends and future directions of environmentally sound and scalable biological strategies for mitigating ECs in WWTP effluents, supporting global efforts toward safer water reuse and environmental protection. By bridging fundamental insights and engineering applications, we aim to support the transition of innovative biotechnologies from the laboratory to the field, providing valuable insights for academics, engineers, policymakers, and other stakeholders committed to achieving high-quality treated water and ecosystem preservation.

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. Applied Sciences 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 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.
