Project location

Summary

• Quincy, Michigan

Infrastructure Alternatives was contracted to remove and dewater 13,500 cubic yards of accumulated sludge from three wastewater treatment lagoons at the ConAgra Foods manufacturing facility in Quincy, Michigan. 

The sludge was hydraulically dredged using an 8 inch diameter auger head dredge and dewatered using mobile (trailer-mounted) belt filter presses.  After dewatering, the sludge was loaded onto trucks and disposed of in a local landfill.

Infrastructure Alternatives served as the General Contractor on this project, providing both hydraulic dredging and mechanical dewatering services.

Project Photo Gallery

(Photo 1 of 5) An 8 inch diameter auger dredge was used to dredge sludge (biosolids) from the wastewater lagoon.

(Photo 2 of 5) A belt press was used to dewater the dredged sludge.  First, the sludge is dosed with chemicals to flocculate the solids.  Then, the flocculated sludge slurry flows onto the belt.

(Photo 3 of 5) As the sludge slurry passes over the belt, water passes through, leaving the solids on top.

(Photo 4 of 5) Dewatered solids then fall off the back of the belt. 

(Photo 5 of 5)  For this project, a conveyor was used to pile the dewatered sludge where heavy equipment could access it.  The dewatered sludge was loaded onto trucks and hauled to landfill for disposal.
