At the Theresa Street wastewater treatment plant in Lincoln, NE a pair of old-fashioned washer-compactors now feed a Screenings Washer Monster. The old-style units didn’t do any washing or compacting so the site called JWC’s SWM to clean up the screenings and do the job properly. The discharged screenings are now much cleaner, drier and have little to no visible fecal content. There’s also no standing water in the dumpster.
The old-style compactors were discharging wet, heavy and fecal-laden screenings. As screenings built up the dumpster would leak foul-smelling liquid all over the ground. (photos by Paul Cockrell)
