ABSTRACT

One of the most important aspects that must be taken into consideration during the operation and management of landfills is their capacity to generate leachate and particular attention must be paid to the protection of surface and ground waters. Leachate is a complex organic liquid formed primarily by the percolation of precipitation water through the open landfill or through the cap of the completed site. To a lesser extent, leachate can be formed as a result of the initial moisture content of the waste. Leachate recycling has been shown to be successful in both pilot and full-scale. The concept of leachate land spraying revolves around the usage of adjacent lands as a natural medium for biological and physical-chemical processes. Biological nitrification-denitrification is considered one of the most suitable methods for removing ammonia from leachate. Evaporation studies have shown that satisfactory results can be obtained with leachate.
