Dredging

Lake dredging removes accumulated sediment but creates large volumes of water-rich sludge that can be difficult and costly to transport. Geotextile tubes provide an efficient solution by separating water from solid sediment through filtration, dewatering, and consolidation. This article explains the lake dredging process and highlights HOKBG’s Yueyang dredging experience in China, showing how geotextile tubes can improve sediment handling and sludge management.

During large-scale canal projects like the Pinglu Canal, dredging, land reclamation, and other river works produce significant amounts of suspended sediments. Without proper control, these sediments can negatively impact water quality, disrupt aquatic ecosystems, and threaten nearby sensitive areas such as mangroves or water intake points.

Geotube dewatering presents a highly effective, cost-efficient, and environmentally friendly solution for managing sediment and liquid waste across diverse industries. This technology utilizes large, permeable geotextile fabric containers that separate solids from liquids through a three-step process: filling, dewatering, and consolidation. Slurry, often treated with polymers, is pumped into the Geotube, allowing water to filter out while solids are retained and compact over time.
