There are a number of commercially available microporous carbons that have a demonstrated affinity for the uptake of metals. Industry currently utilizes in-line storm water treatment processes to remove settle able solids, oils and greases; these processes could easily be altered to include the adsorption of dissolved contaminants such as metals. Two charred microporous polymers, Supelcarb(TM) and Carboxen-1011(TM) were measured for adsorption capacity for Cu(2+) and Ni(2+) removal in both batch and flow through experiments. Results indicate Cu(2+) was removed but not Ni(2+). A scenario was conducted based on experimentally derived Cu(2+) adsorption results to estimate the filter service time for the adsorbers tested when placed with in existing in-line storm water treatment system and exposed to Cu(2+) contaminated storm water. Storm water flows from 1, 2, 5, and 10 years storms were evaluated. Filter service time for the 1 year storm was 3.5 and 6 hours for Supelcarb(TM) and Carboxen-1011(TM) respectively. As storm intensity increased the filter service time decreased. This scenario illustrates that Supelcarb(TM) and Carboxen-1011(TM) are not good adsorbers in this situation. However, removal of heavy metal contaminated storm water by charred microporous polymer adsorption is a viable pollution control strategy.","abstract_html":"This paper examines the feasibility of using an in-line storm water treatment system to remove heavy metals from storm water discharges.
