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
