7.4. Aeration system

7.4.1. Air pump

The air pumps V1 and V2 supply the stages B1
and B2 with the atmospheric oxygen required
for the biological treatment.
Checking the air pumps
During aeration, the carrier
material in the tanks B1 and B2
must be well agitated (small dead
spaces in the corners are not
significant).
However, uniform agitation does
not occur during the run-in period.
If the carrier material is not well agitated,
check:
The hose connections between the air
•
pumps and the diaphragm aerators.
The filters of air pumps for contamination.
•
Replace the filters if necessary.
