Coal Ash / CCR

Superabsorbents for Coal Ash / CCR

Management of coal combustion residuals (CCRs), or coal ash, presents many environmental and operational challenges.  Most CCR impoundments or ponds are saturated with water, which must be removed in order to complete pond closure.  Superabsorbent polymer (SAP) technologies have been proven to rapidly solidify liquid-bearing CCR material and when applied at appropriate dosage rates (less than 1%) are acceptable in structural fill landfills.

Compared to commodity absorbents and pozzolanic materials, SAP technologies feature superior liquid absorbency and retention, which helps CCR site owners, engineers, and contractors minimize CCR disposal, treatment, and transportation costs.

In addition, SAP technologies can enhance the performance features of other treatment additives when utilized as part of specialty blends.
