A Discipline We Specialise In: Sediment Control

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.

Industry Overview

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.

Coarse Separation

Vibrating screens and shale shakers remove large solids, rocks, and debris from slurry and dewatering flows.

Fine Solids Removal

Hydrocyclones and centrifuges remove fine sand, silt, and clay particles for slurry clarification.

Solids Dewatering

Mechanical dewatering equipment reduces moisture content for efficient transport and disposal.

High Capacity

Systems engineered for high-volume applications, handling flows from 100 to 2,000+ m³/hr.

Treatment Process

Multi-Stage Sediment Control

1

Coarse Screening

Vibrating screens remove large debris, rocks, and coarse particles.

2

Desanding

Hydrocyclones separate sand particles (75-1000 microns).

3

Desilting

Finer hydrocyclones remove silt particles (20-75 microns) from the slurry.

4

Centrifugation

Decanter centrifuges remove ultra-fine solids for clarified water.

5

Dewatering

Screw presses reduce moisture content of separated solids.
