Abstract |
The Soliditech process mixes and chemically treats waste material with Urrichem (a proprietary reagent), additives, pozzolanic materials or cement, and water, in aten-cubic yard batch concrete mixer to form a more stable material. This technology was demonstrated in December 1988 at the Imperial Oil Company/Champion Chemical Company Superfund site in Morganville, New Jersey. Contaminated soil, waste filter cake material, and oily sludge, containing PCBs, various metals, and petroleum hydrocarbons were treated. The process was evaluated based on contaminant mobility, measured by leaching and permeability tests; structural and integrity of the solidified material, measured by physical, engineering, and morphological tests; and economic analysis, using cost information supplied by Soliditech, Inc. The conclusions drawn were: (1) process can solidify waste materials containing high oil and grease concentrations; (2) heavy metals such as arsenic, cadmium, lead, and zinc are successfully immobilized; (3) short-term physical stability of the treated waste was high; (4) some long-term tests of the treated wastes indicate a potential for physical degradation, while others indicate stability; (5) treatment results in a 22 percent average volume increase and an average bulk density increase of 33 percent; and (6) the process is economical. |
