7. Recirculation Pump is dual purpose – sprays
wastewater over treatment media & draws
outside air in through use of Venturis
Return Pump sends dead bacteria flock back
to head of primary septic tank & recycles
Nitrified wastewater to anoxic zone
Discharge Pump discharges treated
wastewater to disposal field(s) up to 24
times a day
Control Panel monitors all activity in system
& sends alarm conditions for any problems

25. Nitrogen Reducing Aerobic
Treatment Units
Are Effective at Removing 50-75% of Nitrogen from
Wastewater
Systems Must Fully Nitrify the Wastewater before
Denitrification Can Occur
Must Have Anaerobic & Aerobic Conditions
Other Factors that Contribute to Nitrogen Removal
Plenty of Air
Steady pH
Temperature
Toxicity
Long Retention Times
27. Nitrogen Cycle Simplified
Nitrification — The Conversion of Influent Ammonia to Nitrite & Nitrate
Denitrification — The Conversion of Nitrite to Nitrogen Gas:
Stripping O2 from NO3 to Release N2 (Gas)
“You Must Nitrify Before You Can Denitrify”
