Dewatering Sediments & Sludge: Reducing Treatment Time With Superabsorbents

One of the key principles of employing superabsorbent polymer (SAP) technology for the solidification of dredged sediments, wastewater treatment sludge, or other liquid-bearing waste materials, is the drastic time savings that can be realized with SAPs when compared to traditional, commodity drying products like sawdust or Portland cement.

Why Landfills Prefer Superabsorbent Polymers for Liquid Waste

 

Liquid waste streams such as wastewater treatment sludge (biosolids), coal combustion residuals (coal ash slurries), horizontal direction drilling (HDD) mud, and dredged sediments are challenging to manage for many reasons.  Regulatory restrictions on liquid waste disposal require free liquids to be absorbed, or solidified, prior to acceptance at landfill facilities.  The absorbent material that is selected can impact the landfill’s leachate management costs, the landfill’s longevity, and the water quality in groundwater and surface water in the vicinity of the landfill.  Superabsorbent polymers (SAPs), one of the EPA’s few accepted absorbent materials, help landfills minimize leachate management costs, mitigate environmental risks from leachate leaks, and maximize landfill life.
