|Soliditech, Inc. Solidification/Stabilization
This Applications Analysis Report evaluates the Soliditech, Inc., solidification/ stabilization process for the on-site treatment of waste materials. The Soliditech process mixes and chemically treats waste material with Urrichem (a proprietary reagent), additives, pozzolanic materials or cement, and water, in a ten-cubic yard concrete mixer to form a more stable material.
The Soliditech demonstration took place in December 1988 at the Imperial Oil Company/Champion Chemical Company Superfund site in Morganville, New Jersey. Three types of contamination waste material were chosen for this demonstration -- contaminated soil, waste filter cake material, and oily sludge from an abandoned storage tank. The wastes contain PCBs, various metals, and petroleum hydrocarbons. Extensive sampling and analyses were performed on the waste materials both before and after treatment so that physical, chemical, and leaching properties could be compared.
The Soliditech process was evaluated based on contaminant mobility, measured by leaching and permeability tests; structural integrity of the solidified material, measured by physical, engineering, and morphological tests; and economic analysis, using cost information supplied by Soliditech, Inc. and supplemented by additional information generated during the demonstration.
The conclusions drawn from these evaluations are that:
