RL-3
Comparison of the Performance of the New RL-3 Impeller to the HE-3 Impeller in a Water Treatment Application
Plant Information:
Pinellas County Florida, South Cross Bayou WRF
Application Information:
Anoxic Basin: Start-up in 2000
Basin Dimensions: 40' long by 35' wide by 17' water depth
Plant Flow: 21 MGD average
Agitators Compared:
5hp at 30 rpm unit with 94" diameter HE-3 up-pumping impeller
5hp at 30 rpm unit with 84" diameter RL-3 down-pumping impeller
| HE-3/RL-3 Initial Installation | HE-3/RL-3 After 8 Weeks Operation | |
|---|---|---|
| HE-3 |  |  |
| RL-3 |  |  |
SUMMARY
Maintenance Benefits
- Customer had to drain the basin and increase flow rate to other basins which required manual changes to the process
- Outfitting personnel for basin entry and removal of fibrous material is eliminated
- Disposal issues of fibrous material eliminated
Mechanical Benefits
- Increased up-time of your plant
- Reduces load on agitator system such as gears, bearings, motor, shaft, and impeller blades
- Reduced vibration and increased life of agitator
Process Benefits
- Increased process up-time and elimination of manual process changes
- Elimination of fibrous material on impeller maintains top to bottom flow pattern which improves solids suspension and blending uniformity in basin
- Reliable and consistent discharge within plant operating permit limits
