Special Issue Information

Dear Colleagues,

As human activities, industrialization, pick-up speed, and water contamination with a whole panoply of persistent compounds (e.g., pharmaceuticals, dyes, pesticides, heavy metals, etc.) are becoming a foremost concern. Even at a reduced concentration, due to their severe toxicity to biological amplification and accumulation, these contaminants are considered serious hazards. Prevalent methods for eliminating pollutants from water continue to require excessive energy and chemical consumption, simultaneously leading to secondary contamination, while the treatment often remains incomplete. Many environmental scientists are now primarily focused on making wastewater management both safe and effective in order to successfully treat and recycle the wastewater, mitigate the harmful effects of water pollutants, and assist in preserving freshwater resources.

This Special Issue aims to make available the opportunity to share the most recent investigations and results from the field of safe and effective wastewater management. Outcomes successfully applicable to the treatment and recycling of wastewater, mitigating the harmful effects of water pollutants and preserving freshwater resources, are expected.

We kindly invite willing authors to submit research articles, reviews, case studies, etc., with ground-breaking approaches focusing on (but not limited to) the following areas:

  • industrial waste recycling in view of the use of wastewater treatment;
  • preparation of cutting-edge materials and their application for water decontamination;
  • development of new and affordable technologies capable of removing water pollutants;
  • implementation of eco-friendly practices and methodologies in wastewater depollution;
  • design, optimization, and evaluation of sustainable wastewater treatment processes.

Contributions that are innovative and respectful of the environmental paradigm, particularly those highlighting chemical, biological, or physical processes (advanced oxidation processes, ozonation, electrochemical methods, coagulation, flocculation, adsorption, bioremediation, etc.), are also welcome.

We look forward to receiving your contributions.

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.

This study examined a strategy for effective reject water treatment involving hydrodynamic cavitation (HC) combined with subsequent adsorption using natural zeolites. Two experiments were conducted: The first involved the selection of optimal pre-treatment conditions of HC for biodegradability and to reduce the ammonium nitrogen and phosphate content. Three inlet pressures of 3, 5, and 7 bar and two types of cavitation inducers, i.e., multiple- and single-hole orifice plates, were evaluated. Adsorption experiments were conducted in batch mode using natural zeolite, and three doses of zeolite (50, 100, and 200 g/L) and six contact times (4–24 h) were examined. In the HC experiments, the application of 3 bar pressure, a single-hole cavitation inducer, and a cavitation time of 30 min resulted in the removal of ammonia nitrogen and phosphates amounting to 26.5 and 23%, respectively. In this case, 3.6-fold enhancement in the biodegradability index was also found. In the second experiment, the use of zeolite led to a decrease in the remaining content of both ammonia nitrogen and phosphates, improving the chemical oxygen demand-to-total nitrogen ratio. The highest removal efficacy was found for the highest zeolite dose of 200 g/L and the longest cavitation time of 24 h. Under these conditions, the ammonia nitrogen and phosphate removal rates were 70 and 94%, respectively. Full article
