Soluble silicates 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, non-contaminating solid product that is resistant to the leaching effects
of acid. Applications
