SediCon enables environment-friendly sediment removal from desanders

- The SediCon Desander Dredge removes accumulated sediment from desander basins and similar small structures using gravity-powered hydrosuction. It uses the water-level head between the desander and discharge outlet to draw water and sediment through the system. A patented suction head is intended to provide high removal capacity with low water use; the system can be automated with a winch or travelling crane. An unrestricted-flow/jetting arrangement is described as handling clay, organic material, sand and stones.
- The page says users control when and where sediment is discharged, allowing downstream sediment balance to be managed. Because gravity drives the system, it is described as nearly emission-free. It has few moving parts and low maintenance needs, and can be adapted to existing or new desanders. The article says it operates without affecting normal desander operation, water level or quality, so hydropower generation can continue.
- Desander basins slow water so particles settle and protect turbines from wear. The page says flushing can consume water and reduce power production, while uncontrolled sediment release may create environmental issues. Sediment accumulation can also reduce reservoir volume, power output and discharge capacity and increase equipment and dam stress.
- The market discussion includes older projections of 60% global power-demand growth by 2040, 125 GW hydropower-capacity growth by 2023 and 10,000 TWh/year of unused global hydropower potential. The forecast dates have passed or are historical estimates. SediCon says it was founded in 1999 and had designed and installed patented sediment-management solutions in 20 countries. Other named products include SediCon Dredge, Sluicer and Gravel Excluder.
