Abstract :
Background and Objective: In recent decade, various researches have been performed on the application of nanoparticles in the water and wastewater industries. In generally, these nanoparticles are divided to carbon nanotubes, metal oxide nanoparticles. Carbon nanotubes have a high active specific surface, while easy reuse. Metal oxide nanoparticles have the proper selectivity for absorbing toxic compounds and heavy metals. Polymeric nanoadsorbents have Bifunctional (inner shell adsorbs organics, outer branches adsorb heavy metals) and reusable. Zeolites have high specific surface and adsorption ability. In this paper has been studied a review of nanoadsorbents and their applications in water and wastewater treatment systems. Analysis methodology: Research documents and data have been gathered based on review articles methodology by searching the reference data banks of articles and scientific resources and researches conducted inside and outside Iran in the field of nano adsorbents for water and wastewater treatment systems. Findings: The results of this study shows that there are many research about iron oxide and carbon nanotubes, but less research is done in the field of silver nanoparticles with high antibacterial properties to remove viruses, bacteria and fungi from water and wastewater. Discussion and Conclusions: Regard to development and applications of nanoabsorbents in the field of water and wastewater treatment systems, it is suggested that researches with an applied and industrial point of view be considered in the research and scientific centers of the country to enable the possibility of water recovery and optimization of the treatment system.
