Case Study, Landfill Leachate treatment
After dose nitrifying and denitrifying bacteria, denitrifying tank ammonia reduction efficiency reach to 89.94%;
Nitrifying tank ammonia reduction efficiency reach to 95.99%
Aeration tank ammonia reduction efficiency reach to 97.87%
Nitrifying bacteria and denitrifying bacteria can tolerance 700 mg/L high ammonia parameters.
Flow rate: Landfill Leachate 80 ~100 cmd /day;
Raw Water NH4-N : 1,580 mg/L, Nitrifying tank NH4-N: 700 mg/L;
Flow Diagram: EQ tank > Denitrifying tank > Nitrifying tank > Aeration tank > Sediment > UF > RO
System with high level ammonia nitrogen, incompliance with discharge limited standard.
Client would like to reduce ammonia nitrogen below 25 mg/L.
