What is S/S Treatment for Remediation?

Involves mixing a binding/reaction agent(s) into contaminated media such as soil, sediment, sludge or industrial waste. S/S treatment protects human health and the environment by immobilizing hazardous constituents within treated material. Physical (solidification) and chemical (stabilization) changes to the treated material. Mobility Reduction Terms: Stabilisation (UK), Inertage (France), Immobilization (EU).

Efficient Use of Binders Matters

Binders do matter!

Most of the cost in a mass stabilization project comes from the binder, which represents about 50-70 % of the total project cost.

Efficiencies (Cost Savings) are

improved by:

  • Thorough mixing (mixing shear &

energy) resulting in intimate contact of binder and subject material.

  • Introduction of binder at mixing

point.

  • Locating and metering of binder

to avoid under-dose and

  • verdose.
  • Use of dry binders in wet

materials to conserve drying capacity of binders.

Binding Agent Pricing

  • Priced by transportation costs:

− Industrial waste/byproducts, finely divided materials

available on site, e.g. spent fullers earth, ash

  • Priced per ton:

− Common construction materials:

  • portland cement, blended cements, Class C or F fly ash,

GGBFS, lime.

  • Priced per pound:

− Specialized materials, sorptive, reactive, or

compounding

  • Carbons, organophilic clays, oxidizers, reducers
