Onsite evaporation using waste energy solves disposal challenges

摘要

Landfill managers agree that dealing with landfill leachate is challenging, expensive, and a regulatory headache - yet the leachate just keeps coming. In fact, the annual costs for managing landfill leachate are counted in the billions and continue to rise. Landfill leachate includes the wastewater that accumulates in landfills from rainfall as well as the decomposition of organic waste. While percolating through the garbage, the wastewater dissolves and entrains organic material, chemicals, metals, and minerals - whatever is in the garbage -resulting in a nasty mixture of contaminants that is unlike any other wastewater. Moreover, the mix of contaminants in the leachate changes constantly. Cover discipline by the landfill operator, volume of precipitation, and variations in garbage make-up dramatically alter the contaminants in landfill leachate.
