RNR Environmental provides two approaches for wet dredged sediment and dredging slurry: rapid solidification for handling and disposal, or moisture reduction when reducing disposal weight and preserving material for potential recovery or reuse is the better objective.
RNR supplies application-matched industrial absorbents for wet sediment, dredging slurry and other water-rich materials. Available options include general-purpose ZORBZALL® SAP, high-salinity-resistant SAP and specialty SAP/mineral blends for water affected by emulsified oils or elevated hydrocarbon concentrations. When properly matched to the waste stream, high-efficiency absorbents may control free liquid with substantially less added material than high-volume bulking agents. Representative sample testing determines the appropriate product and dosage.
Where excess moisture drives hauling and disposal costs, RNR can evaluate options to reduce the water and weight transported. Depending on the material, this may also preserve potential recovery or reuse. Results and economics depend on the material and project requirements.
For dredged material destined for disposal, RNR can develop a treatment approach around the receiving facility's requirements, including the Paint Filter Liquids Test where applicable. Dosage and treatment performance are determined using the customer's actual material.
Some dredged sediment may have value for beneficial reuse once excess water is removed. Where contamination, chemistry and local requirements allow, RNR can evaluate moisture reduction while minimizing added material so the sediment can be assessed for potential recovery or reuse.
RNR supports commercial dredging projects with bulk ZORBZALL® SAP supply and project-specific treatment evaluations. Send a representative sample to assess dosage, handling requirements, and estimated treatment economics before full-scale use.
