Dredging 24/7 in a nature reserve park to reduce the amount of orthophosphate.

Lake Teterow is situated in a nature park, approximately 200 km North from Berlin, in former East Germany. It is a beautiful shallow lake measuring 1,500 acres with an average of 4 metres depth. Restoring Lake Teterow is a perfect example of where we do valuable work in rural nature and reduce the amount of orthophosphate, locked in its silt.

From dusk until dawn 24/7, our dredger constantly pumped its mixture into one of the 12 dewatering basins. To achieve the highest accuracy, we used the RTK-GPS and a Dredge Monitoring System. A Multicat was used to assist the dredger in repositioning its anchors and the extension of the (floating) pipeline.

To reduce the amount of dissolved orthophosphate, we used inhouse designed environmental friendly dispensing units. These solar powered units inject poly aluminium chloride into the 3 precipitation basins. Samples were taken frequently, and proven by lab testing, that the remaining pumping water contained less than 80 μg of orthophosphate.
