Abstract
Clean water is a vital need for all living creatures during their lifespan. However, contaminated
stormwater is a major issue around the globe. A wide range of contaminants, including
heavy metals, organic and inorganic impurities, has been discovered in stormwater. Some commonly
utilized methods, such as biological, physical and chemical procedures, have been considered to
overcome these issues. However, these current approaches result in moderate to low contaminant
removal efficiencies for certain classes of contaminants. Of late, filtration and adsorption processes
have become more featured in permeable concretes (PCs) for the treatment of stormwater. As
nanoparticles have vast potential and unique characterizations, such as a higher surface area to cure
polluted stormwater, employing them to improve permeable concretes’ capabilities in stormwater
treatment systems is an effective way to increase filtration and adsorption mechanisms. The present
study reviews the removal rate of different stormwater contaminants such as heavy metals, organic
and other pollutants using nanoparticle-improved PC. The application of different kinds of nanomaterials
in PC as porous media to investigate their influences on the properties of PC, including
the permeability rate, compressive strength, adsorption capacity and mix design of such concrete,
was also studied. The findings of this review show that different types of nanomaterials improve
the removal efficiency, compressive strength and adsorption capacity and decrease the infiltration
rate of PC during the stormwater treatment process. With regard to the lack of comprehensive
investigation concerning the use of nanomaterials in PC to treat polluted stormwater runoff, this
study reviews 242 published articles on the removal rate of different stormwater contaminants by
using PC improved with nanoparticles.
