In this study we have in pilot scale tested different methods for treatment of leachate from a
municipal solid waste (MSW) landfill, Only to focus on sum parameters, nutrients and metals
when designing treatment methodology for landfill leachate is not enough, it is also important
to measure the content of toxic organic compounds in low concentrations, However, it is not
practical to analyse all substances in the leachate and for making evaluation of treatments
feasible our own analytical protocol was created, The efficiency of tested treatment
procedures was evaluated by measuring changes in concentrations of a number of chosen
parameters and organic compounds before and after treatment The treatment methods tested
that showed the highest efficiency towards organic pollutants in leachate were ozone
treatment and chemical oxidation with Fenton's reagent However, more natural based
methods like filtering the leachate through a bed with peat mixed with carbon containing
bottom-ash showed promising results.
