Human activities have had detrimental effects on water quality; for that reason, the water remediation is a topic extensively studied by many research groups around the world. In this context, the research on the removal of pollutants from ground waters or industrial effluents by using physical or chemical methods has acquired increased attention in the last decade. The study of different alternatives for the water source treatment allows either improving or developing processes to clean water not only for human consumption but also for guaranteeing a safe discharge of water stuff by reducing its toxicity to other life species.

The main objective of this special issue is to present and discuss scientific and technological developments that are expected to contribute to improving the existent processes for water remediation. High-quality scientific articles, original research manuscripts, as well as review articles focused on pollutants removal from water are welcome as contribution for this special issue.

Potential topics include, but are not limited to:

• Emerging pollutants, hazardous materials, and metals removal
• Advanced oxidation processes
• Photocatalysis
• Ozonation
• Electrochemical treatments
• Process integration and intensification
• Toxicity of polluted and treated water
• Materials development for water remediation
• Technology assessment for water remediation
• Analytical techniques for pollutants identification or quantification
