As underground construction projects continue to demand cleaner slurry recycling, stable tunnel-face support, and efficient solids removal, TBM slurry separation plants are becoming a critical part of modern tunneling operations. For projects in South Korea, GN Solids has supplied six slurry separation plants designed for slurry balance TBM applications, helping contractors manage drilling slurry more efficiently on site.
These systems are built around two practical processing capacities, 500 m³/h and 750 m³/h, allowing project teams to select a configuration that matches different tunneling conditions and slurry return volumes. Rather than focusing only on equipment shipment, the value of the system lies in how it improves slurry circulation, solids control, and day-to-day site management.
At the core of each plant are three essential treatment stages: scalping screen shale shaker, desander, and desilter. This staged separation approach allows coarse particles, sand-sized solids, and finer particles to be removed progressively, supporting more stable slurry quality for reuse in slurry-supported tunneling. GN’s public product information also highlights compact, modular slurry separation design as a key advantage for TBM and pipe jacking projects, especially where working space is limited.
For contractors, modular design matters just as much as treatment performance. A compact system is easier to transport, install, relocate, and maintain. Pre-assembled or modular process sections can also shorten site setup time and reduce disruption during project mobilization. In urban or restricted jobsite environments, this small-footprint approach can make a meaningful difference in project execution.
GN Solids Control continues to expand its role in global slurry treatment applications by providing practical solutions tailored to real project requirements. The South Korea TBM slurry separation plant project reflects GN’s ability to combine processing efficiency, modular engineering, and reliable manufacturing into a solution that supports demanding tunneling operations with confidence.
