Dredging Solutions FAQs

What is dredging, and why is soil dewatering important?

Dredging removes accumulated sediment from waterways, harbors, and ponds to restore depth, capacity, and environmental quality. Dewatering the dredged spoil is essential to reduce disposal volumes, lower transportation costs, and enable water reuse—all while supporting compliance with environmental regulations.

Dredging serves critical needs across multiple industries:

  • Maritime ports and shipping channels
  • Municipal stormwater pond management
  • Environmental remediation contractors
  • Industrial facilities and refineries
  • Golf courses and recreational facilities
  • Emergency response operations

Dredging operations rely on various mechanical and hydraulic systems to remove sediments:

  • Cutter suction dredges (CSD)
  • Trailing suction hopper dredges (TSHD)
  • Hydraulic dredges and jet pumps
  • Mechanical clamshell dredges
  • Auger dredges for confined spaces
  • Environmental dredging systems

While these methods handle sediment removal, dewatering the resulting slurry requires advanced solids control solutions to manage spoil volumes efficiently. Decanter centrifuges are the gold standard for this phase of the operation. They provide continuous, high-throughput separation, delivering superior dryness of recovered solids while maximizing clean water recovery. 

Compared to alternatives like belt presses or settling ponds, centrifuges offer faster processing, smaller footprints, and greater flexibility—making them the preferred choice for demanding dredging projects.

Our dredging solutions center around Alfa Laval decanter centrifuges supported by complete auxiliary systems:

  • Large and small-bowl decanter centrifuges
  • Shale shakers and dewatering shakers
  • Polymer mixing and dosing systems
  • Sediment transfer and booster pumps
  • Pre-treatment and clarification equipment
  • Spoil conveyance and storage systems
  • Complete electrical and control packages

Mobile centrifuge systems offer several advantages for dredging operations, including:

  • Compact footprint compared to belt presses or large settling ponds
  • Continuous processing that matches dredge production rates
  • Superior cake dryness and clean water recovery
  • Fully enclosed systems require fewer operators, reducing personnel risks
  • Low maintenance costs thanks to robust design and quality materials
  • Excellent handling of varying feed conditions

Yes. Every system is configured around your actual project parameters: sediment type, slurry consistency, flow rate, and site constraints. We optimize centrifuge selection, control settings, and auxiliary equipment to match your specific dewatering requirements and site conditions.

We maintain a ready-to-deploy inventory with shipping in as fast as 48 hours. Our systems are designed for minimal maintenance, featuring robust construction and high-quality components. We provide 24/7 field service, preventive maintenance programs, and immediate parts replacement for uninterrupted operation.

Absolutely. Our centrifuge systems excel at processing varying sediment types, from fine harbor silts to coarse construction spoil. The equipment handles fluctuating solids concentrations, particle sizes, and slurry consistencies without requiring reconfiguration or downtime.
