N2 - The results of a bench-scale evaluation of an ion exchange process concept for continuous removal of dissolved metals from dilute wastewater streams are disclosed. The novel hybrid magnetic-field pipe reactor was designed to regulate the residence time of magnetic particles (pre-coated with an ion-exchange resin) relative to the wastewater residence time. The experimental data showed that initial concentrations of arsenic, chromium, lead, and silver were substantially lowered after surrogate solutions of each metal were individually processed in the reactor system. The lead and silver concentrations in the metal-depleted reactor discharge solutions were reduced to levels approaching or below their Toxicity Characteristic Leaching Procedure (TCLP) limits.
