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 natural weathering and erosion, sediments are carried and deposited in the mentioned water bodies. 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 in the form of water intake cleaning is needed to keep the water basins clean and the capacity of the industrial plant at its maximum.
