How it Works
The ABC®-N denitrification device is designed primarily for use as a denitrification (nitrate reducing) device when exceptional levels of nitrogen reduction are required. A carbon feed system (by others) supplies a carbon source, and the ABC®-N promotes the growth of bacteria that denitrifies nitrified wastewater from most wastewater flows. The ABC®-N system combines naturally occurring bacteria (biomass) with an external carbon source to denitrify wastewater that has been nitrified by an upstream aeration system such as FAST®. This is a continuous process provided; the biomass is supplied with food (carbon) and oxygen (nitrate molecule) in a suitable environment.
How it Installs
The ABC®-N process consists of the treatment module with re-circulation pump and assembly. The re-circulation pump and assembly mixes nitrates (NO3) and carbon throughout the media inside the tank. Bacteria grows on the media and uses the nitrates as oxygen, thereby transforming the nitrates into harmless nitrogen gas (N2). Dead bacteria and non-biodegradable waste settle and accumulate in the bottom of the septic tank as sludge for periodic removal.
Finding the Right Size
It is recommended to check what local regulations are required in case additional information is needed.
