In recent years, nanomaterials have gained special attention for removing contaminants from wastewater. Nanoparticles (NPs), such as carbon-based materials and metal oxides, exhibit exceptional adsorption capacity antimicrobial properties wastewater treatment. Their unique properties, including reactivity, high surface area, tunable functionalities, make them highly effective adsorbents. They can remove organics, inorganics, pharmaceuticals, medicine, dyes by mechanisms. this review, the effectiveness of different types NPs, carbon nanotubes (CNTs), graphene-based nanoparticles (GNPs), quantum dots (CQDs), nanofibers (CNFs), nanospheres (CNSs), copper oxide (CuO), zinc (ZnO), iron (Fe2O3), titanium (TiO2), silver (Ag2O), in removal has been comprehensively evaluated. addition, their synthesis methods, physical, chemical, biological, described. Based on findings, CNPs 75 to 90% pollutants within two hours, while MONPs 60% 99% dye 150 min, except NPs. For future studies, integration NPs into existing treatment systems development novel are recommended. Hence, potential is promising, but challenges related environmental impact toxicity must be considered.

Wastewater Remediation Treatments Aimed at Water Reuse: Recent Outcomes from Pilot- and Full-Scale Tests

Applied Sciences, Journal Year: 2025, Volume and Issue: 15(5), P. 2448 - 2448

Published: Feb. 25, 2025

Remediated water reuse is becoming vital for sustainable management, reducing the strain on freshwater resources, particularly in agriculture and industrial activities. Behind application irrigating crops processes, treated should be employed indirect direct potable use. In latter case, traditional approaches to wastewater treatment have been found inefficient, especially concerning biological contamination, persistent organic pollutants (POPs) and/or contaminants of emerging concern (CECs). Given that, according its origin foreseen use, each needs a specific treatment. A plethora new or improved materials, combinations different treatments check analyses are continuously developed tested at laboratory scale, first, necessary but not sufficient, step towards solution. Various innovative were pilot reduced number procedures applied full resulting significant production remediated desired quality. The present review focuses most recent outcomes obtained from remediation both scales discusses gaps which still hinder exploitation solutions advancements real-scale application.
