LAKVATTENRENING IDAG OCH IMORGON-TEKNIKÖVERSIKT OCH NÅGON FUNDERING / Landfill leachate treatment today and tomorrow. A technical review and some thoughts
Landfill leachate treatment methods are discussed and their effects are reviewed. The lack of agreement between actual treatment effect and the goals and methods that have been proposed by the Swedish Environmental Protection Agency are elucidated. The knowledge of what the recipient that is exposed for land-fill leachate actually can stand is argued as the most important fact when choosing the correct landfill leachate treatment method. The applicable policy to exclude organic materials in landfilling is assessed to result in a faster leaching of inorganic material from the landfills, which can lead to a leachate with higher salt and mineral concentration and probably a higher toxicity. It is not obvious that this situation is the most wanted.
