A Note on the Advances in Adsorption Technology for Water Treatment: Progress and Challenges

Abstract

This note briefly summarizes the progress and advances in adsorption technology for water remediation. Although numerous adsorbents have been developed and examined in water treatment, their potential needs to be further assessed on pilot scale with real surface/ground water and/or wastewater. Development of some synthetic, hybrid and nano-scale adsorbents show high efficiency towards specific pollutants removal, but more research is needed prior to their use in full-scale application in water and wastewater treatment.
