Utilisation of Pervious Concrete for Removal of Heavy Metals in Contaminated Waters: Opportunities and Challenges

Abstract

While a number of studies have been done on the use of pervious concrete for stormwater runoff management and improvement of water quality with respect to total suspended solids, phosphorous, and nitrogen, hardly any articles have summarized the recent progress on the use of pervious concrete for the removal of heavy metals from aqueous solutions. This work aims t o provide a review of current knowledge relevant to the use of pervious concrete in the remediation of water containing high metal concentrations. In addition, the challenges, limitations, and prospects of pervious concrete applications in heavy metal removal from polluted water are discussed. The potential use of pervious concrete as a low cost reactive barrier system for the removal of heavy metals present in polluted waters is a promising alternative to current treatment methods.
