GN Separation has announced the successful deployment of its flagship linear dewatering screen and big bowl decanter centrifuge at a U.S.-based engineering slurry treatment facility. Recent operational images shared by the client highlight GN’s expertise in delivering tailored solutions for complex industrial separation challenges.
Linear Dewatering Screen: Precision in Primary Separation
GN’s linear dewatering vibrating screen is purpose-built for handling high-volume slurry streams with superior efficiency. Powered by dual vibrating motors, it delivers consistent screening performance even in abrasive environments. The modular screen panel design allows fast and flexible replacement, reducing downtime during maintenance, while the compact structure simplifies installation. The result is minimized clogging and maximized throughput.
High-Speed Decanter Centrifuge: Advanced Secondary Separation
Working in tandem with the dewatering vibrating screen , GN’s big bowl decanter centrifuge delivers high-speed, fine-particle separation. Operating at forces up to 3,000g, the centrifuge separates solids as fine as 2–5 μm and achieves dry solids content of up to 75%. Adjustable conveyor speed and pond depth settings enable operators to adapt performance to a wide range of feed materials, from clay-heavy slurries to chemically conditioned wastewater. Constructed with duplex stainless steel and fitted with tungsten carbide tiles, the decanter centrifuge is engineered to resist abrasion and corrosion, extending service life in demanding environments.
Synergistic Application in Slurry Treatment
Together, GN’s linear dewatering vibrating screen and decanter centrifuge form an optimized two-stage process for slurry treatment, designed to maximize water recovery and minimize waste:
Primary Separation – Linear Dewatering Screen
Raw slurry is first fed into the dewatering screen. Vibratory linear motion separates larger particles while water and fine solids pass through, significantly reducing the solids load for downstream processing.
Secondary Separation – Decanter Centrifuge
The effluent from the screen is pumped into the decanter centrifuge, where centrifugal force accelerates sedimentation. Clarified water is discharged for reuse in applications such as concrete production or irrigation, while the dewatered solids are conveyed for safe disposal.
Advantages of the Combined System
Enhanced Water Recovery – Maximizes reclaimed water, reducing dependence on freshwater and lowering regulatory risks.
Lower Disposal Costs – Produces drier solids, cutting transportation and landfill expenses.
Regulatory Compliance – Ensures treated water meets stringent discharge standards, avoiding penalties and protecting reputation.
