The goal of this project was to test the efficiency of a full-scale air stripping process designed to remove ammonia and total nitrogen from landfill leachate at the Shanghai Laogang Solid Waste Disposal Facility, Ltd., located in Shanghai, People's Republic of China. Leachate samples were collected before and after air stripping, and tested for quality. Overall, air stripping reduced ammonia by 4 -- 15%, total nitrogen by 0 -- 29%, and chemical oxygen demand by 27 -- 42%. The air stripping process was then redesigned by increasing the treatment time and treatment volume to remove 70 -- 80% of ammonia from landfill leachate.
