How it works: Soluble silicates have been shown to react with hazardous wastes
to produce less hazardous substances. They do so by converting soluble metals
into insoluble metal silicates and by encapsulating hazardous organic and
inorganic components within an acid-resistant matrix. Silicates also react with
calcium-based stabilizers to produce a superior final product. Using soluble
silicates to treat a waste stream typically results in a strong,
low-permeability, chemically stabilized solid that is easy to handle, transport,
and landfill.
Using soluble silicate in waste treatment:
Reduces the amount of setting agent required for complete stabilization,
thereby reducing raw material costs.
Reduces the final volume of stabilized material requiring disposal,
further reducing total treatment costs.
Modifies the set time of setting agents to improve processing.
Enhances final physical properties of the stabilized waste resulting in a
stronger, less permeable matrix.
Produces a stable solid product that is resistant to
the leaching effects of acid.
