Landfill leachate is identified as an environmental concern, as it contains both eutrophicating and hannful substances. Collection and treatment of leachate is therefore a necessity and most landfills in Sweden treat the leachate before discharge into any recipient. More and more landfills changes to local treatment and at Moskogen and Hedeskoga landfills Soil-Plant (SP) systems were designed to replace the conventional treatment of leachate at the municipal sewage treatment plant. Installed in 1998, the SP-system at Moskogen have removal efficiency today for some key parameters of about: 97% for BOD; 41 % for COD; and for NH4-N 99%. The SP-system at Hedeskoga was planted with cuttings (Salix) in the spring of 1999 and the system was put into operation in the summer and the removal efficiencies for pollutants in the ponds was in July for: BOD 80%; COD 65%; Tot-N 87%; and NH4-N 94%.

Municipal Sewage Treatment Plant

In this investigation it was found that the waste sludge obtained from a municipal sewage treatment plant could be reclaimed as an adsorbent for removal of organic vapours, i.e. toluene, methyl-ethyl-ketone and 1-1-2-trichloroethylene, through use of a pyrolysis technique. In order to find the optimum manufacturing process, several tests were performed under various conditions in which the addition of a catalyst, temperature control, and residence time in the furnace, were considered as the three major factors. Both the reclaimed adsorbent and commercially available activated carbon were evaluated to determine their adsorption capacity at various influent concentrations of organic vapours.
