Abstract
Laboratory studies were performed to prove the concept and feasibility for a novel technology to dewater sludges. This involves the formation of solid hydrate crystals of water and specific clathrate-forming agents followed by separation of the hydrate crystal solids from the sludge solids, producing a sludge solids mass depleted of water content. The objectives were to dewater sludges from the Millcreek Wastewater Treatment Plant in Cincinnati, Ohio. Tests were performed using Freon-11 as clathrate-forming agent, in a bench-scale batch mode.
