New Perspectives for Water Quality and Wastewater Remediation: Advanced Oxidation Processes and Toxicity Assessments

Dear Colleagues,

We are thrilled to introduce the Special Issue “New Perspectives for Water Quality and Wastewater Remediation: Advanced Oxidation Processes and Toxicity Assessments”, featured in the esteemed open access journal, Water, published by MDPI. This Special Issue serves as a comprehensive platform for the exchange of knowledge, research findings, and innovative approaches related to both water quality and purification, wastewater remediation—focusing on AOPs—and toxicity assessments, with a focus on assuring environmental safety.

The growth in the global population and urbanization, dwindling clean water supplies, increased environmental concerns, and the strong link between water quality and human health necessitate the identification and implementation of effective sustainable water purification and wastewater treatments to meet the urgent global demand for adequate, safe, and easily available water resources. Overcoming the crisis of sustainable water resources and wastewater management is of the utmost importance.

The promotion of the safe use of purified water and the affordable and adequate availability of wastewater treatment techniques are major steps toward sustainable wastewater management. The gap between the standard achieved by traditional physico-chemical and biological treatments and the more stringent daily limits set by environmental regulations is closed by Advanced Oxidation Processes (AOPs). AOPs have shown tremendous promise for water purification and wastewater and industrial wastewater treatment, including the elimination of contaminants of emerging concern, pesticides, naturally occurring toxins, and other deleterious anthropogenic pollutants. AOPs cannot yet be regarded as mature, despite significant advancements, and there are still many unexplored areas that merit further study. In addition, chemical analyses can only detect a few pollutants, which are not always consistent with the toxic effects of wastewater. Toxicity tests reveal adverse biological effects on mixed pollutants in WWTPs, which can be used to indirectly assess the efficiency of wastewater removal. A variety of toxicity tests have been developed to assess the negative effects of wastewater, based on previous studies using bacteria, microalgae, invertebrates, plants, and fish, with some focusing on only one or a small number of test species.

This Special Issue warmly welcomes original research articles, reviews, case studies, and critical analyses that delve into and address the following issues:

• New challenges in wastewater treatment;
• Wastewater remediation;
• Water purification;
• Water quality;
• Advanced Oxidation Processes;
• Photoinduced processes;
• Transformation products;
• Toxicity assessments.

Yours faithfully,
