WaterSolve, LLC was awarded the contract for removing residuals from a portion of a wastewater lagoon at a large pulp and paper mill in Wisconsin. Large amounts of solids continued to accumulate in the inlet side of a large primary lagoon. Based on preliminary measurements, it was estimated that 9,200-c.y. of residual was to be removed. In the past, the solids were removed mechanically and allowed to dewater by gravity. The excavator could not reach the entire area, leaving a large amount of residuals in the lagoon. The solids did not dewater effectively, making the handling and hauling very difficult. This prompted the pulp and paper mill utility personnel to evaluate alternate residual removal and dewatering methods.

CHEMICAL CONDITIONING

WaterSolve, LLC completed a Dewatering Trial Performance on March 4, 2010 to determine the most effective chemical conditioning based on a composite sample obtained from the project site.  WaterSolve, LLC also performed an on-site Geotube® Dewatering Test (GDT) on March 8, 2010.  The results of this testing were presented in a report.

GEOTUBE® CONTAINER SIZING

Geotube® containers are manufactured from high strength polypropylene fabric and designed to allow effluent water to escape through the pores of the fabric while retaining the chemically conditioned solids.

THE RESULT

The dewatering and consolidation of the residuals in the Geotube containers was even greater than anticipated.  The paper mill personnel were extremely pleased with the results of the dredging and dewatering project.
