Large alpine hydropower plants are the backbone of Swiss electricity production. The Energy Strategy 2050 aims to further increase their efficiency, but small particles in the water, i.e. sediments, stand in the way of this goal. Fine sediments carried by rivers act like sandpaper on the turbines of power plants and obstruct them. This problem is well known and power plants operate desanding facilities designed to reduce the suspended load. These systems consist of elongated basins in which the water flows very slowly, allowing the particles to settle on the bottom. But even the latest generation of these facilities only partially fulfil their purpose. For this reason, turbines require more frequent maintenance work, causing electricity production downtime and financial losses. In Switzerland alone, annual costs are estimated at approximately 6 million Swiss francs.
