SAPs for Environmental Remediation
Manage Coal Ash (CCR or Fly Ash)
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.
Liquid-bearing wastes such as wastewater treatment sludge, contaminated sediments, mine tailings, tank bottom sludge and many other industrial waste streams are challenging and costly to manage and pose severe threats to the natural environment.
Superabsorbent polymers (SAP) are widely used by site remediation contractors to rapidly solidify liquid-bearing waste on-site for transport and disposal at solid waste landfills.
Compared to commodity absorbents and cement-products, SAP technologies offer superior absorbency and retention which allows remediation professionals, waste treatment facilities, and landfills to minimize treatment amendment quantity, time on-site, disposal costs, and releases of contaminants to the natural environment. Furthermore, SAPs are safe to handle and do not require special health and safety precautions or PPE.
