Incomplete NitrificationA condition in which not all ammonia is converted to nitrate (some of the ammonia remains as ammonia and some of the ammonia undergoes partial conversion yielding concentrations of nitrite). Typically, incomplete nitrification results in high levels of ammonia in the wastewater effluent.
|
Incomplete DenitrificationA condition in which environmental conditions are not optimal to provide for the conversion of nitrate to nitrogen gas (some of the nitrate remains as nitrate and some undergoes partial conversion yielding concentrations of nitrite). Typically, incomplete denitrification results in high levels of nitrate in the wastewater effluent.
