Among the problems created by the proliferation of wipes is the unpleasant, time-consuming and costly job of periodically pulling rags from pumps.
Many clean-water plants have tackled the problem by installing choppers or grinders that macerate the wipes into particles that pumps can easily pass. Now United Kingdom-based Clearwater Controls (doing business as DERAGGER in the U.S.) offers a technology that instead uses intelligent pump control to allow wipes to pass without cutting.
The DERAGGER+ anti-ragging device monitors the pump’s power signature and detects when a wipe is interfering with the pump’s operation. At that point, it runs the pump through a reverse cycle that releases the wipe, which then passes through when normal operation is restored.
