Product: Geotube® Dewatering Technology
Application: Pulp & Paper
The pulp and paper mill needed to remove 170,000 cubic yards of anaerobic sludge for their primary Activated Sludge Basin (ASB) -- all without interrupting the mill operations.
The sludge was dredged from the ASB lagoon at a rate of 2,800 gpm with a cutter head dredge into 30,000 linear feet of 60' circumference GT500 Geotube® dewatering containers. The sludge material was contained and dewatered in the Geotube® units within a landfill site built on the paper mill's property.
The dewatering operation was conducted in four phases over a two-year period with a dewatered material average of 45.7% solids.
