5 COMMISSIONING
Pre-operational Inspection
Inspect and ensure the following requirements are met:
• The system is accessible and nothing inhibits maintenance.
• Surface water is draining away from the system.
• The system is filled with water, is level, and each component functions properly.
• There is no damage to the tank, piping, or other components.
• There are no air leaks in the air piping and the air piping is connected correctly.
Start Up the System
Step 1.
Make sure electrical power is supplied to the system and all electrical components are plugged in
properly.
Step 2.
Make sure the blower operates properly. To test: turn OFF the air blower for a few moments to
check that the alarm is triggered. Note: As there is a 60 second delay designed into the alarm, it
will take 60 seconds until the air fault alarm is triggered.
Step 3.
Lift up the pump float switch to check that the pump operates properly and lift up the high water
float switch to check that the alarm is triggered. Note: it will also take 60 seconds until the high
water alarm is triggered. Check alarm monitoring unit as well as remote alarm plate for alarm
activation.
Step 4.
Set the Effluent Control Valve to 40, and then make sure that the Effluent Air-lift Pump works
while the water level is above the LWL.
Step 5.
Visually observe the airflow rates on each side of the Aerobic Contact Filtration Chamber to verify
equal flow. If there is an obvious discrepancy in airflow between the two sides, adjust the Aeration
Balance Control Valve so that the airflow is equal.
Step 6.
Step 7.
Measure the recirculation rate at the end of the recirculation pipe while the water level is at the
LWL. The recirculation rate should be approximately 4 to 6 times as much as the inflow rate. If the
daily inflow volume is obtainable, calculate the appropriate recirculation rate accordingly.
Otherwise set the rate to 3 – 5 L/min.
Fill the chlorinator and adjust the dissolve rate if applicable.
