Water intake dredging and cleaning

Water intake dredging is used to retain cooling capacity and overall efficiency of industrial plants. Large industrial plants such as petrochemical plants, power plants and desalination plants use water intake channels for cooling purposes. These water intakes are commonly connected to lakes, rivers, canals or the open sea. Due to factors such as weathering and erosion, sediments are carried and deposited in the mentioned water bodies. Therefore, in order to avoid their entering the industrial plant, water intakes are equipped with sand traps or screens.

However, over time, sediments can accumulate at the trap. As a consequence, less water can enter the industrial plant, which limits its cooling capacity and results in reduced overall efficiency. Therefore, regular maintenance dredging is needed to keep the water basins clean and the capacity of the industrial plant at its maximum.

water intake Dredging equipment

Water intakes can often be difficult to access and may require precise dredging. Auger dredger ECO 200 is a small dredger, ideal for cleaning freshly accumulated sediments in a precise manner. On the other hand, a cutter suction dredger is more suitable in the cases when sediments have accumulated over a longer period of time and have become compact. Both types of dredgers feature a compact design, making them easy to transport, launch and store for later use.
