WEF Releases 10 Thickening and Dewatering Factsheets
Dewatering typically occurs after biological and digestion processes and further removes water from the solids slurry. This process produces a material that can be transported for disposal or beneficial use. The solids cake that is produced from dewatering is typically 15% to 40% solids and acts as a solid — that is it no longer can be pumped.
