Description:
The solidification/stabilization technology mixes hazardous wastes, cement, water and an additive called Chloranan. Chloranan, a nontoxic chemical, encapsulates organic molecules, rendering them ineffective in retarding or inhibiting solidification. This treatment technology immobilizes the contaminants from soils by binding them into a concrete-like, leach-resistant mass. After contaminated soil is excavated and screened out for oversized material, it is fed to a mobile field blending unit to treat the wastes. The unit consists of soil and cement holding bins, a Chloranan feed tank and a blending auger to mix the waste and pozzolanic materials (portland cement, fly ash or kiln dust). Then water is added as necessary, and the resultant slurry is allowed to harden before disposal. The treated output is the contaminants bound by encapsulation into a hardened, concrete-like mass. For the treatment of large volumes of waste, larger blending systems are also available.
