Special Issue "Resource Recovery and Removal of Organic and In-Organic Contaminants from Wastewater"

Dear Colleagues,

Due to the rapid growth of population, industrialization, and urbanization, water pollution has been increasing at an alarming rate, affecting living beings and the environment as a whole. The wastewater generated by anthropogenic activity is chemically complex in nature due to the presence of a wide variety of contaminants, such as heavy metals, dyes, pesticides, fertilizers, organic acids, halogenated and phenolic compounds, pharmaceuticals/drugs, pesticides, herbicides, endocrine disrupting chemicals, etc. These pollutants, even at low concentrations, can be very harmful to human health and aquatic life. Therefore, wastewater should be treated before it is discharged into water bodies via effluents. To counteract the causes of pollution and the protection of the environment, many techniques have been developed. Some of these techniques are adsorption, membrane separation, precipitation, coagulation/flocculation, photocatalysis, etc. The goal of these methods is to separate, capture, and remove/destroy pollutants from water. However, the recovery of energy or value-added material from wastewater is becoming an essential practice to make the process sustainable. Several valuable metals, inorganic resources (e.g., N, P, and S), H₂, and value-added organic compounds (e.g., lipids, proteins, carbohydrates, and organic acids) can be recovered from wastewater. These value-added compounds can be used as raw materials in several applications, such as biofuel, bioplastic, bio-fertilizer, animal feed, building materials, pharmaceuticals, and so on.

The purpose of this Special Issue is therefore to collect recent state-of-the-art research and review articles on wastewater treatment and circular economy. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

1. Wastewater treatment by different methods;
2. Material science;
3. Membrane technology for water purification;
4. Advanced oxidation process;
5. Resource recovery;
6. Biofuel production from wastewater;
7. Concept of Sustainability;
8. Drinking water disinfection.

We look forward to receiving your contributions.

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. Sustainability 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.
