Landfill leachate treatment for metal removal by filtration through reactive substrates - column experiment

Ten columns made of PVC tubes with an internal diameter of 9.8 cm were filled with substrate to a height of 50 cm. Two types of leachate water from a landfill in Södertälje, Sweden, were pumped to the columns with a load of 528 L/m2/day during four months. Five columns filled with different substrates received leachate from the ash deposit at the landfill. The remaining five columns received a mixed leachate from the whole landfill area. Both unsaturated and saturated conditions were used for pairs of columns with identical substrate. The metal sorption capacity was investigated. Columns filled with Polonite® (product from opoka) showed best overall performance. Highest average removal efficiency was obtained by fine-grained Polonite mixed with peat where Co, Cr, Cu, Zn and Mn were removed by 10, 12, 31, 45 and 99%, respectively. High removal efficiencies for all metals can only be obtained with multi-substrate filters, having metal specific sorption capacities.
