3-blade impeller RL-3

for agitatorsaxial-flow

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 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
