DREDGED SEDIMENT DEWATERING & SOLIDIFICATION

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.

ZORBZALL® super absorbent polymer rapidly absorbs free liquid in wet sediment, dredging slurry and other water-rich materials. Low treatment dosages can produce a more manageable solid with minimal added bulk compared with high-volume bulking materials.

When excess moisture is driving hauling and disposal costs, RNR WasteShrink™ Technology can be evaluated to reduce moisture, weight and waste volume rather than simply adding material to the waste. The objective is fewer tons hauled and disposed when the application is suitable.

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 and sediment projects bulk super absorbent polymer (SAP) supply with ZORBZALL®. and projects with specific treatment evaluation. Send RNR a representative sample to determine treatment performance, dosage and projected economics before full-scale implementation. Call RNR: 818-606-1673 | rob@rnr-enviro.com
