Treating Ammonia in Landfill Leachate

May 4, 2020

In this Waste Today article, Sam Cooke discusses the factors, treatment options,  analytical methods,  and identifying PFAS sources to most effectively reduce the concentrations of ammonia and PFAS in landfill leachate.

Reducing these concentrations help meet discharge permit requirements for direct discharge of treated leachate to surface waters and to meet publicly owned treatment works (POTW) discharge permit standards.

Sam points out that accomplishing ammonia and PFAS reduction with established wastewater treatment technologies works, but the right treatment depends on each site’s specific parameters. He suggests conducting bench-scale and pilot-scale testing for any feasible nitrogen removal or treatment system.  Testing the wastewater helps to identify any changes in the concentration of nitrogen compounds. Thus, necessary changes to the treatment processes, such as additional aeration or chemical additions are easier to identify and less costly to implement.
