This powerpoint presentation begins by presenting a brief overview of a project at the Cleveland Division of Water (CWD) to investigate nonmechanical dewatering in addition to other dewatering technologies for residuals management. A brief overview of nonmechanical dewatering is provided, along with three reasons the City is interested in residuals management that include economics, environment, and social equity. Components of sand bed sizing are presented, including the following: theory; drainage; field plots; warm weather testing; modeling; and, cold weather results. Summary of findings includes the following: by partnering with industrial landowners, CWD could feasibly utilize sand drying beds for residuals management; sand drying beds may be suitable option for meeting CWD's triple bottom line; and, further effort required for negotiation with potential partners and conceptual bed layout and design Nonmechanical dewatering can meet all three bottom lines. Includes figures.
