Nanoremediation has been most widely used for groundwater treatment, with additional extensive research in wastewater treatment. [5] [8] [9] [10] Nanoremediation has also been tested for soil and sediment cleanup. [11] Even more preliminary research is exploring the use of nanoparticles to remove toxic materials from gases. [12]
Nanotechnology offers the potential of novel nanomaterials for the treatment of surface water, groundwater, wastewater, and other environmental materials contaminated by toxic metal ions, organic and inorganic solutes, and microorganisms. Due to their unique activity toward recalcitrant contaminants, many nanomaterials are under active research ...
Many different types of nanomaterials or nanoparticles are used in water treatment processes. Nanotechnology is useful in regards to remediation, desalination, filtration, purification and water treatment. The main features that make nanoparticles effective for water treatment are More surface area; Small volume
Ozone is a strong oxidizing agent widely used in the treatment of printing and dyeing wastewater, [3] and coal chemical wastewater. [4] Its solubility in water is less and stability is also poor, which will reduce the degradation capacity of ozone towards organic molecules. [ 5 ]
Magnetic nanobeads or nanoparticle clusters composed of FDA-approved oxide superparamagnetic nanoparticles (e.g. maghemite, magnetite) hold much potential for waste water treatment since they express excellent biocompatibility which concerning the environmental impacts of the material is an advantage compared to metallic nanoparticles.
Airborne and waterborne nanoparticles enter from building ventilation and wastewater systems. [22] Effect of nanoparticles on societal issues: As sensors become commonplace, a loss of privacy and autonomy may result from users interacting with increasingly intelligent building components. [22]

Nanobubbles and nanoparticles are often found together in certain circumstances, [16] but they differ in that nanoparticles have different properties such as density and resonance frequency. [17] [18] The study of nanobubbles faces challenges in understanding their stability and the mechanisms behind their formation and dissolution. [19]
