Product: Geotube® Dewatering Technology
Application: Pulp & Paper
Location: St. George, New Brunswick, Canada
The black liquor sludge lagoon at the plant was full, and it was about to overflow into the adjacent river [photo 1]. An immediate lowering of the sludge level was required.
This urgent situation was addressed with the use of Geotube® Dewatering Technology. The project involved 1,400 linear feet of GT500 Geotube® dewatering containers (45' circumference x 60' long) to contain and dewater the solids dredged from the lagoon. The containers were positioned in an existing on-site landfill for dewatering. The pumping and dewatering continued uninterrupted during all types of weather at the clean-up site.
In less than seven days, 19,800 cubic yards of sludge were removed from the lagoon. The sludge dewatered to greater than 50% solids after a three-month period [photo 5]. The Geotube® units remained permanently in the landfill space.
