Providing clean and affordable water to meet human needs is a grand challenge ofthe 21st century. Worldwide, water supply struggles to keep up with the fast growingdemand, which is exacerbated by population growth, global climate change, and waterquality deterioration. The need for technological innovation to enable integrated watermanagement cannot be overstated. Nanotechnology-based multifunctional and highlyefficient processes are providing affordable solutions to water/wastewater treatmentsthat do not rely on large infrastructures or centralized systems. Here we review recentdevelopment in nanotechnology for water and wastewater treatment. The discussioncovers candidate quantum dot (QD) nanoparticles such as ZnS, CdSe/ZnS core-shells,graphene, l-glutathione-capped-ZnSe, Cu2O Quantum Dots and their application onmethyl violet, colored organic pollutant, TNP, copper and organic contaminantremoval. The results show that water/wastewater treatment using QDs is a promisingfield for current & future research.
