Macerator Explodes, Monster Sludge Grinder Takes Over

The Coeur D’Alene, ID, wastewater treatment plant was having continual problems with two sludge macerators, in part because of the durability of the macerator. During design someone misread the max PSI rating as 150 — while the macerator’s true max pressure rating is 30 PSI. Eventually, one of the macerators exploded and flooded the underground pump area with sludge.

It took about 12 hours for operators to clean up the mess after the macerator exploded, but the crew pulled a Muffin Monster grinder from their back-up stock, and it took care of the sludge immediately. Read the full case study to learn more.
