Leachate from landfill
is wastewater, which is accumulated on the bottom of a compartment or a landfill. The composition and the hydraulic flow of this water depends on the type of waste which was stored, the annual and momentary precipitation and last but not least the age of the landfill.
Older landfills drain less biodegradable organic matter (BOD/COD relation to zero). Typically pollutions can be high nitrogen concentrations (NH4, N02, N03, various hydrocarbons – often organ halogens, chlorides, sulphates, different heavy metals
(i.e. Zn, Cu, Ni, Cr, Cd, Hg, Pb and more)
The water usually shows less turbidly, it has a less brown color and mostly a penetrating smell can be detected. So in short: it is highly polluted, it has fluctuating hydraulics and it requires various process technologies to meet the effluent requirements, according to the local regulations.
