river sediment Applications

  • PAHs in Sediment

    Sitelab's laboratory performed a 4 day site investigation testing PAHs in sediment on the West Branch Grand Calumet River in Indiana. Test data was used to fingerprint and map the river bottom contaminated with heavy crude oil.

  • 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.

    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.

    Compressed air, gas and vacuum solutions for water and waste water treatment

    There are many options to apply methods to avoid damaging the environment. In the case of wastewater e.g. the ventilation of the sediment tank or the pressure ventilation of biological wastewater treatment systems. The oxygen introduction is important, for deep wastewater tanks, wastewater treatment systems with standard aeration tanks or natural clarification ponds alike. If the wastewater has already entered the natural cycle, ventilating lakes and rivers prevents additional contamination. When treating drinking water, rinsing the filters with compressed air ensures that perfect water is provided and natural water reserves are not used excessively.

    Water Treatment Solutions for Turbidity Removal

    Turbidity is a measure of the loss of light transmittance through a liquid due to suspended particles. The more particles in the water, the murkier it looks or the higher the turbidity. This is a measure of the quality of the water. It is measured in units called Nephelometric Turbidity Units (NTU). Turbidity can be caused by run off after a heavy rain as erosion washes soil into a river or lake. It is often increased in the spring and fall when the water temperature at different levels in a lake change causing a turnover of those levels, bringing sediment, plants, and algae to the top.
