Special Issue Information
Dear Colleagues,
Constructed wetlands (CWs) are engineered ecosystems designed to mimic natural wetlands, offering sustainable solutions for water treatment and environmental remediation. This Special Issue explores recent advancements and innovative approaches to enhance the performance of CWs in removing and remediating contaminants. Key topics include optimizing CW designs to improve the removal of nutrients, heavy metals, organic pollutants, and emerging contaminants like pharmaceuticals and personal care products (PPCPs). Innovative strategies, such as integrating microbial fuel cell (MFC) technology with CWs, are highlighted for their potential to simultaneously treat wastewater and generate electricity. Contributions also examine the role of plants, substrates, and microbial communities in improving contaminant removal efficiency and promoting system stability. Attention is particularly devoted to addressing challenges such as clogging, greenhouse gas emissions, and the management of microplastics and other persistent pollutants. Comparative studies on vertical flow, horizontal flow, and hybrid CW configurations provide insights into selecting optimal designs for specific treatment goals. Further, this issue delves into scaling up laboratory studies to real-world applications, focusing on cost-effectiveness, long-term performance, and the role of CWs in climate resilience and water reuse initiatives. By bridging research and practice, this Special Issue aims to advance the understanding and application of CWs as versatile, eco-friendly systems for mitigating global water pollution challenges. Researchers, engineers, and policymakers are invited to explore these cutting-edge contributions to shape the future of sustainable water management.

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. 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.
