No Operations Building Required
Integrates with Other Technologies
SeptiTech Technology
SeptiTech Advantages
Third Party VerificationsETV, NSF 40 & 245
Best treatment numbers including Denitrifiction
98%+ Removal of BOD/TSSUp to 85% Removal of Nitrogen
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

tal Effects
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

Requires Oxygen (4.6 lb/lbN) Uses up Alkalinity (7.1 lb/lbN)
Nitrifers
Removing Nitrogen Biologically
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)

Operations & MaintenanceOnsite Visual Inspection of All System Components
Tank, pumps, float switch, control panel, auto-dialer and
audio/visual alarm
Visual inspection of electrical splices and contacts,
check/record amperage and voltage readings
Visual inspection of filter media or filtration device(s)
Exercise all mechanical valves
Sensory examination of treated effluent for clarity, odor, oily
sheen, foaming or any other unusual characteristics
Record flow data (volumetric, cycle counter, etc.)
Maintain bound inspection log with entries for all service activities,
observations, and field test readings with entries recorded in ink.
