- A laboratory experiment demonstrated the use of reactive bed filters to effectively remove metals and other elements from landfill leachate. Filter media composed of sand/peat, blast furnace slag (BFS)/peat and Polonite®/peat were tested by loading filter columns with leachate collected from a pond at Tveta Landfill, located in Södertalje, Sweden. Leachate was discharged to each column with a hydraulic loading rate of 1.34 m/d. Sand and Polonite® represent natural materials, although the latter is manufactured from the bedrock opoka. BFS is a by-product from steel-works. Polonite® provided the best removal capacity when compared to the other media. Mn, Fe, Zn and Cu were removed by 99%, 93%, 86% and 67% respectively. This filter media was also able to reduce phosphorus by 90% and nitrogen by l8%.The BFS showed good removal efficiency for Cu (66%), Ni (19%) and Mo (16%). Reactive bed filters may be an economical and practical method for augmenting current, and future onsite treatment of landfill leachate disposal systems with metal, phosphorus and nitrogen removal capabilities.
