Landfill leachate is a fluid that is from the external water which enter into the landfill solid waste, dissolve and rinse the dissolved materials including organic matter. It usually has high content of organic matter, electrical conductivity and high concentrations of nitrogen, toxic compounds and heavy metals. Hence, formation of landfill leachate threatens the public health and environment. Proper treatment of landfill leachate is therefore vital to remove hazardous components before discharge. Further, composition of landfill leachate varies from time to time and site to site. There are number of leachate treatment methods which have been used. Some methods are inefficient, and some are expensive and energy consuming and thus not suitable for many landfill sites, particularly in rural areas of developing countries.
