Evaluation of Zn, Cu and Pb sorption-desorption phenomena in kaolinite-sand media filtration pilot scale installation
| Summary: | The retention of Zn, Cu and Pb from highway runoff with reactive filter media was studied. Besides the physical retention of traditional filter beds, a reactive filter bed enhances the dissolved heavy metals retention processes due to sorption and precipitation, transferring pollutants from the dissolved form to the media matrix. A synthetic effluent was used to simulate highway runoff and, for filter bed media, sand and kaolinite were used. Results obtained for those three heavy metals show a very high reactive filter media retention capacity and a very high resistance to desorption processes. |
