Landfill leachate treatment using hybrid process With fixed zeolite bed

Landfills leachates are generated from water percolating through the landfill body and biochemical processes in waste during their decomposition. They contain a large number of harmful inorganic and organic substances, heavy metal salts and soluble gases created by dissolving and decomposition of waste materials on their path. Single treatment method is not efficient for achieving satisfactory leachate effluent quality, thus combination of various treatment methods called “hybrid” is interest of many scientists. This paper examines treatment of landfilled leachate by hybrid process with fixed zeolite bed. In order to avoid secondary pollution during in situ application, desorption of harmful substances from saturated zeolite in column has been investigated.
