IWWG Training Course: Leachate treatment
Chair / Presidente: H. Robinson (UK)
At both operational and closed landfill sites in every country, the management of leachate remains a key issue in order to prevent adverse environmental impacts. In addition, management of leachates is the most important factor that will determine the aftercare period for closed landfills; while the majority of landfill gas generation will be completed within about 50 years, the flushing out of soluble contaminants released during wastes decomposition as leachate, will take many centuries. This training course will provide a brief introduction to processes of waste decomposition and leachate generation and composition, but will then focus on state-of-the-art leachate treatment processes, based on detailed operational data from many full-scale leachate treatment plants, in temperate and tropical climates, and in developed and developing countries. Case studies from some of the largest and most advanced leachate treatment plants in the world will be presented and discussed, with plenty of opportunity for delegates to discuss their own leachate problems, and try to find ways in which they can select appropriate technologies, or improve operation of existing treatment systems.
