The characteristics of leachate from landfills vary according to site-specific conditions. Leachates old are often rich in ammonia nitrogen, posing potential adverse environmental impacts the case uncontrolled discharge. At where recirculation is practiced, concentrations may accumulate higher levels than during single pass leaching. Using with system modifications, separate aerobic and anoxic zones for nitrification both autotrophic heterotrophic denitrification can be provided. Results simulated landfill bioreactors indicated that nitrogenous sulfur compounds attenuated through denitrification, nitrate 750 mg/L reduced less 1 by nitrogen gas promoting this very common process a environment results reduction sulfate concentrations.
