Sepra offers various technological solutions for the purification of landfill leachate, composting.
Landfill leachate is characterized by high organic and inorganic pollutant concentrations (Bodzek et al., 2006) and is extremely toxic to the environment. The significant impacts of landfill leachate could be eutrophication of aquatic systems and toxic effects on fauna which are caused by a variety of contaminants (Lavrova and Koumanova, 2010).
Typical constituent concentrations in landfill leachate are 1000 mg/L BOD5, 18,000 mg/L COD, 225 mg/L TN, 30 mg/L TP, 1000 mg/L Ca, 250 mg/L Mg, 500 mg/L Na, 300 mg/L K, 60 mg/L Fe, 500 mg/L Cl−, and 300 mg/L (Tchobanoglous and Kreith, 1998).
Due to its high toxicity, landfill leachate is a major threat for aquifer and surface water health status (Bulc, 2006).
