Many lakes developed an oxygen-free zone on the ground and are now threatened to silt up. What are the reasons for that? And more importantly, how can we prevent it? BERKY produces and sells a wide range of dredging boats made in Germany that offer tailormade solutions.

One of the main initiators causing siltation is called eutrophication. In ‚healthy‘ waters, the dead residues of plants and animals are sinking to the ground. By using oxygen, special bacteria are transforming the organic substances to inorganic compounds, which are returned to the nutrient cycle.
