Complete water treatment for tunnel boring machines and construction dewatering.
Removing sediment and suspended solids from tunnel construction water — the first and most universal treatment step on any underground site. We show it because almost every downstream consent and process depends on getting solids out first. Coarse screening and grit removal protect the downstream plant, while coagulated lamella clarification drops fine and colloidal solids that will not settle on their own. Getting suspended solids out first stabilises pH and oil treatment that follow and is usually the difference between meeting and breaching a turbidity consent.
Specialised Solutions for Sediment Control
Underground construction generates large volumes of solids-laden water from TBM slurry, dewatering operations, and site runoff. Effective sediment control is essential for slurry recycling, environmental compliance, and efficient project execution. Our sediment control systems provide multi-stage solids separation from coarse screening to fine particle removal, with integrated dewatering for efficient solids disposal. Screens, hydrocyclones, lamella clarifiers and dewatering presses combine to recover clean water and a stackable solids cake for easy disposal. This keeps TBM and dewatering operations running while protecting drains and watercourses from silt.
Vibrating screens and shale shakers remove large solids, rocks, and debris from slurry and dewatering flows.
Hydrocyclones and centrifuges remove fine sand, silt, and clay particles for slurry clarification.
Mechanical dewatering equipment reduces moisture content for efficient transport and disposal.
Systems engineered for high-volume applications, handling flows from 100 to 2,000+ m³/hr.
