Nanotechnology, the engineering and art of manipulating matter at the Nano scale (1-100 nm) are increasingly evident in all areas of science and technology, including the field of environmental studies and treatment of surface water, groundwater and wastewater contaminated by toxic metal ions, organic and inorganic solutes and microorganisms. Due to their unique activity toward recalcitrant contaminants many nanomaterial’s are under active research and development in the treatment of wastewater. This paper brings together a technical set of information that demonstrates the range of complex issues that need to be considered and addressed in applying these technologies (Nano scale zero Valente iron, nanocrystalling zeolites, bimetallic particles, nanoscale Semiconductor photo catalysts, ferritin, self assembled monolayers on mesoporous silica, dendrimers, polymeric nanoparticles, tunable biopolymers, single-enzyme nanoparticles), including how these individual nanotechnologies might eventually be implemented for improving basic sanitation and access to clean water.
