#264 Dewatering Lagoon Residuals

This glue manufacturing plant in Illinois needed to dewater residuals from the wastewater storage pond and haul them to a landfill. The characteristics of the glue caused problems for mechanical dewatering equipment. WaterSolve, LLC did some testing on site as well as in the lab and determined the residual could be dewatered with a Geotube® and the proper chemistry. A pilot study was performed the summer of 2009. The material dewatered fine and 24% dry wt solids were achieved by the fall. They now plan to repeat the process as a standard practice.
