Dear Colleagues,

In the past few decades, scientific understanding of water chemistry has progressed tremendously, leading to development of state-of-the-art wastewater and water treatment technologies. However, the quality of fresh water sources has continuously deteriorated around the globe, in both industrialized and developing countries. While traditional wastewater technologies are focused on removal of suspended solids, nutrients and bacteria, occurrence of hundreds of organic contaminants in wastewater and impacted urban surface waters. These new contaminants are synthetic or naturally occurring chemicals that are not commonly monitored in the environment, but which have the potential to enter the environment and cause known or suspected adverse ecological and (or) human health effects. Collectively referred as the "Emerging Contaminants" (ECs), these contaminants mostly originate from domestic use and occur in trace concentrations ranging from pico to micrograms per liter. ECs are recalcitrant to conventional wastewater treatment process and most of them remain unaffected leading to the contamination of receiving water. This scenario leads to the need for advanced wastewater treatment process capable of removing ECs to safe guard fresh water sources. 

This Special Issue will focus on wastewater technologies specifically developed for treatment of emerging contaminants in domestic wastewater. The issue will be a collection of various original studies and reviews evaluating the efficacy of existing technologies and novel treatment technologies for treatment of ECs. Fate of ECs during conventional wastewater treatment processes will also be included. The collection will also encompass investigations that address the issue ECs in municipal sludge and biosolids and their treatment.

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. ChemEngineering 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 1600 CHF (Swiss Francs).
