Table 1
Examples of potential applications of nanotechnology in water/wastewater treatment.
Applications
Examples of nanomaterials
Some of novel properties
Adsorption
CNTs/nanoscale metal oxide and nanofibers
High specific surface area and assessable adsorption sites, selective and more adsorption sites, short intraparticle diffusion distance, tunable surface chemistry, easy reuse, and so forth.
Disinfection
Nanosilver/titanium dioxide (Ag/TiO2) and CNTs
Strong antimicrobial activity, low toxicity and cost, high chemical stability ease of use, and so forth.
Photocatalysis
Nano-TiO2 and Fullerene derivatives
Photocatalytic activity in solar spectrum, low human toxicity, high stability and selectivity, low cost, and so forth.
Membranes
Nano-Ag/TiO2/Zeolites/Magnetite and CNTs
Strong antimicrobial activity, hydrophilicity low toxicity to humans, high mechanical and chemical stability, high permeability and selectivity, photocatalytic activity, and so forth.
