#331 Dredging and Dewatering Biosolids

In the state of  Washington , awastewater treatment facility’s lagoon system had  biosolids buildup. They were remote from any farmland or landfill to dispose of the material and preferred to use Geotube® dewatering to consolidate the biosolids before transferring them off site. The objective was to dredge the biosolids into the Geotubes, dewater the material to reduce the volume and pass a paint filter test, and then either apply it on farmland or dispose of it in a landfill.
