POSTER PRESENTATION

Thermal Treatment for Reclamation of Contaminated Sediments

Contaminated sediments directly affect commerce and economic development, establish long term liabilities and compromise the watershed.  Accepted practice for remediation of contaminated sediments after dredging has been to either relocate them or bury them at sites determined to minimize health impacts and remove the material from public view. However, the potential for health and environmental risks of the contaminated sediment remain.  A new treatment process was tested using Passaic River sediments. In this process a mixture of sediment and modifiers were charged to a rotary kiln that operated at temperatures between 2,500 - 3,000 °F.  The sediment-modifier mixture was chemically and thermally transformed to a homogeneous, pozzolanic, glassy melt. Organic toxins were destroyed.  Inorganic contaminants (including metals) were immobilized within the melt matrix.  Flex and compression tests showed that the product exceeded requirements for Portland cement.
