Leachate extraction and treatment systems utilize submersible pumps to remove contaminated groundwater from solid-waste landfill sites and a variety of treatment technologies on the surface to remediate the groundwater before discharge. The available treatment processes have the ability to remove most organic and inorganic contaminants typically found in leachate, including: metals, suspended solids, ammonia, and hydrocarbons.
Leachate is extracted using pneumatically-driven pumps, and is transported to the treatment system on the surface. The types of treatment processes used are dependent on the composition of the leachate and the required discharge quality. The treatment technologies available include: membrane biological reactors, advanced oxidation, chemical treatment, pH adjustment, air strippers, and a wide range of media filtration options.
Important to consider in the design of leachate extraction and treatment systems are the types of contaminants, the level of contamination, and the expected flow rate of leachate.
