    Environmental dewatering solutions for environmental dredging

    TenCate Geotube technology helps to dewater and contain contaminated sediments in rivers, bays, harbors, marinas, ports, dock facilities, hydro basins and other waterways.  In many cases, these sediments pose significant environmental hazards, and remediation is a difficult and expensive task.

  • SONARtrac - Dredging - Cutter Vessels

    Cutting efficiency is greatly affected by variability in soil density, hardness, lithology, and sediment particle size distribution. All of these factors create slurry of variable makeup and density. If the dredge pump works at a constant speed, the slurry will have a variable flow velocity, which is undesirable and potentially dangerous. If the velocity is too low, there is a risk of sandouts in the pipeline. If the velocity is too high, the pump will wear and be inefficient. Traditional velocity flowmeters with wetted parts are prone to wear, causing measurement inaccuracies, and require frequent, costly replacements

  • Automated solutions for the power plant inlet water dredging

    Liquid Waste Technology’s dredging systems are used for power plant cooling water dredge applications. LWT’s dredges are designed to remove the sand, silt and sediment that build up in reception ponds and inlet channels to power plants. Each dredging system is custom built for the inlet water application, including the level of automation, removal rate and dredging depth required for each job.

  • SONARtrac - Dredging - Hopper Vessels

    Soil density, hardness, lithology, and sediment particle size distribution can create slurry of variable makeup and density. At a constant pump speed, the slurry will have a variable flow velocity, which is undesirable and potentially dangerous. If the velocity is too low, there is a risk of sand outs in the pipeline. If the velocity is too high, the pump will wear and be inefficient. Traditional velocity flow meters with wetted parts are prone to wear, causing measurement inaccuracies, and require frequent, costly replacements. In addition, the presence of entrained gases may disturb the readings of traditional flowmeters and cause slurry density measurements to be inaccurate.

  • River and canal maintenance

    When maintaining rivers and canals Watermaster Classics excellent moving capabilities and versatile tools are of prime importance. When Watermaster works, it does not disturb passing traffic because it anchors with its own spuds, unlike one-purpose machines, which require cables for anchoring and stop the other traffic while working. Watermaster Classic is an excellent solution for accurate dredging. It can remove an exact layer of sediment from the bottom. Its excellent moving and anchorage capabilities enable efficient dredging in places where dredging has to be done in several different areas of the river. Watermaster Classic does not need external help to move from one place to another. Precision dredging is especially needed when exact hydrometrical modelling has been done. Watermaster Classic ensures the right results which are effective and long lasting.
