Unusual Water Levels - Troubleshooting
Observation
Possible Cause
Corrective Action
The water level in the
pre-treatment is
unusually high, water
level in the aeration
is normal.
•
The lifter at valve 1 is not triggered.
•
The pumping time for lifter 1 is set too
short.
•
The charging lifter is congested.
