VIDEO Phosphorus filter system for drainage water at Venner Bruchkanal (Germany)

07 December 2021 - Published by Charlotte Boeckaert
The Lower Saxony Chamber of Agriculture (LWK Niedersachsen) has developed a filter shaft that collects and filters the phosphorus-containing water from a drainage system shortly before it flows into the receiving water.

Iron-coated sand is used as filter material. This is a by-product of the regional drinking water production of the Wasserverband Wittlage.
