City Plunges Forward, Flushing Problems and Saving Over $100,000 in 8 Months Post-Installation Away

These items cluster together, forming “rag balls,” detrimental to wastewater treatment plants. The system is comprised of three RAS pumps (return-activated sludge) that require a manual clean-out 21 times a week, costing $3,000 weekly. The process for the maintenance team was time-consuming, disruptive, and dangerous:

• Shut down the pumps.
• Pull the pumps up.
• Dislodge the blockages from the sharp
  impellers by hand.

After years of research, the city installed three DERAGGER® systems, one for each pump at the plant.

The city installed a DERAGGER® system to monitor the pumps’ amperage, voltage, and hertz outputs and sense potential overloads. If a clog is detected, the DERAGGER® reverses the direction of the blades on the pump impellers, eliminating the clog or rag. By enabling Real Time Pump Protection™ to detect rags and run a clean cycle, DERAGGER® clears the first rag and prevents a clogged pump. Eight months post-installation, there were no shutdowns, and the city saved over $100,000. Installing DERAGGER® saves money and time and improves operator safety.
