ABSTRACT
Sanitary landfill is recognized as the most common and desirable method for eliminating urban solid waste. It is also considered as the most economical and environmentally acceptable method for eliminating and disposing of municipal and industrial solid wastes (Tengrui et al. 2007). However, sanitary landfill generates a large amount of heavily polluted leachate (Zazouil and Yousefi 2008). The generation of leachate is mainly caused by a release from waste due to successive biological, chemical, and physical processes of waste deposited in a landfill. The quality and quantity of the water formed at landfills depend on several factors, including seasonal
weather variations, land filling technique, phase sequencing, piling, and compaction method (Amonkrane et al. 1997; Trebouet et al. 2001).
