Special Issue Information

Dear Colleagues,

In recent years, the reuse of wastewater has increased dramatically due to the constant increase in water demand. This is due both to population growth and urbanization and to climate change. From this perspective, research in the field of advanced water management and treatment has increased significantly. New technologies have emerged to address new challenges, such as the degradation of persistent pollutants and emerging contaminants, non-biodegradable wastewater, and pathogens.

This Special Issue welcomes submissions on advanced wastewater management and treatment including but not limited to:

- Physico-chemical processes (membrane technologies, coagulation-flocculation, etc.);

- Advanced oxidation processes (photocatalysis, ozone Fenton, activated persulfate, sonochemistry, electrochemical oxidation, etc.);

- Applications of new catalytic materials for advanced wastewater treatment;

- Combination of biological and physicochemical processes—hybrid treatment;

- Advanced biological treatment (moving bed and membrane bioreactors, etc.);

- Bioremediation and phytoremediation;

- Studies carried out in pilot plants or related to size scaling;

- Applications of artificial intelligence to advanced waste treatment;

- Simulation of advanced treatment of wastewater or drinking water.

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 papers will be 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. Environments is an international peer-reviewed open access monthly 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 1000 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.

The coffee industry generates a significant amount of wastewater that is rich in organic loads and is highly acidic. The present study investigates the potential of the heterogeneous photocatalytic oxidation process to reduce the pollutant load in coffee processing wastewater. The experimental runs were conducted to evaluate the effect of operative parameters such as pH, catalyst dosage, intensity of UV light irradiation, and addition of oxidant on Chemical Oxygen Demand (COD) and colour reduction. Significant results for COD and colour removal, 67%, and 70% respectively, were achieved at a pH of 4 with titanium dioxide (TiO2), and a catalyst dosage of 500 mg/L, using four ultraviolet-C (UV-C) lamps of 16 W each. With the addition of hydrogen peroxide (H2O2) as an oxidant, the removal efficiency increased to 84% and 75% for COD and colour, respectively. Finally, the best results obtained by photocatalytic degradation using UV light were compared to those using solar light. Based on the investigation, it was inferred that the pollutant removal efficiency in coffee pulping wastewater was also considerably high under sunlight. These findings may have relevance in terms of application in countries where coffee processing is carried out and where sunlight irradiance is usually strong: the technique could be exploited to decrease the pollutant content of this wastewater sustainably.
