GN Modular Vacuum and Hydraulic Excavation Sludge Dewatering System Delivered to Overseas Client

GN Solids Control has recently completed the delivery of a fully modular sludge dewatering system designed for vacuum and hydraulic excavation applications. The complete system has been shipped to an overseas customer and is tailored to handle high-solid-content slurry generated from utility excavation, HDD, and similar applications where vacuum trucks or hydrovacs are used to collect slurry from job sites.

This turnkey solution integrates five main modules, each engineered for efficient, staged separation and compact, flexible installation.
1. Coarse Shaker Module – GNLMP-1536
The process begins with the GNLMP-1536 Coarse Shaker Module, designed to handle large volumes of incoming slurry while efficiently removing oversized solids, rocks, and debris. This helps protect downstream equipment and ensures a smooth process. The modular design makes it ideal for fast mobilization and deployment on-site.

2. Double Deck Fine Shaker Module – GNZS596K
Following the initial coarse screening, the slurry is processed by the GNZS596K Double Deck Shaker, which uses high-G force vibration to separate finer particles. The double-deck design allows for more effective separation with increased throughput, improving the efficiency of the entire system.

3. Desander/Desilter Module – GNZJ594J-8N
The third stage includes the GNZJ594J-8N Desander and Desilter Module, equipped with 10” and 4” hydrocyclones to remove sand and silt-sized particles from the slurry. This step is critical in reducing the solid load before the slurry enters the decanter centrifuge, thus enhancing overall performance and extending equipment lifespan.
4. Decanter Centrifuge Module – GNLW553D-VFD
The GNLW553D-VFD Decanter Centrifuge is the core of the dewatering process. With a large bowl diameter and variable frequency drive (VFD), this centrifuge is capable of handling high slurry volumes with excellent separation efficiency. It removes fine particles and reduces the total solids content to meet environmental discharge or disposal requirements.

5. 20ft Chemical Dosing Module
To further enhance separation efficiency, the system includes a 20ft Containerized Chemical Dosing Unit. This module automatically prepares and injects flocculants or coagulants into the slurry, improving the performance of the decanter centrifuge and allowing for the recovery of cleaner water and drier solids.
