Frequently Asked Questions
What is slurry separation?
Slurry separation is the process of removing solids from a slurry stream so the solids and water can be handled more efficiently. In dredging applications, that usually means screening and dewatering raw slurry from the pump discharge to reduce water handling, improve solids dryness, and create a more efficient downstream process.
Why is dredged slurry different from drilling mud?
Dredged slurry is typically more abrasive, less uniform, and more likely to contain debris, organics, shells, mixed particle sizes, and rapidly changing solids concentrations. Drilling mud systems were not designed around those conditions, which is why they often underperform in dredging duty.
What is the patented 4D Separation System™?
The 4D Separation System™ is a patented four-layer screening approach that separates and dewaters slurry in stages. The layered design helps manage solids loading, reduce blinding, improve throughput, protect lower decks, and produce drier solids discharge.
What is a 4D shaker screen?
A 4D shaker screen is a multi-layer screen panel that combines a coarse scalping layer with additional separation and dewatering layers inside one panel. It is intended to improve material distribution, protect lower screens, and produce drier solids in high-solids slurry service.
Can the system process slurry directly from the pump?
Yes. The system is designed for direct pump-to-shaker integration so slurry can be processed immediately rather than routed through settling ponds or other secondary handling steps.
What materials can the system handle?
Depending on the application and the system configuration, it can handle sand, silt, clay, organics, ash, mixed sediment, dredge spoil, and other abrasive or variable-solids slurry streams.
What does a slurry separation agitator do?
An agitator helps keep solids suspended, improves feed consistency, and reduces settling in pits, tanks, ponds, and process vessels. That can support better performance downstream when the material reaches the shaker or dewatering stage.
What are the main benefits of direct pump-to-shaker separation?
The main benefits are reduced pond footprint, faster processing, better water recovery, drier solids, lower handling cost, and a cleaner production flow from excavation to solids discharge.
What information do you need to recommend a system?
The most useful inputs are slurry type, expected solids concentration, flow rate, pump type, deployment layout, particle characteristics, and the customer’s production or dewatering goal.
Is this a complete system offering or just a screen technology offering?
The primary positioning is a complete slurry separation platform built for dredging and high-solids dewatering. The patented 4D screen technology is a major differentiator inside that broader system offering.
