ViviMag – Phosphorus recovery solutions are needed for municipal wastewater to reuse precious phosphorus

Phosphorus recovery solutions are needed for municipal wastewater to reuse precious phosphorus. Several methods have been developed over the years, and some are commercially available. However, those treatment facilities using chemical phosphorus removal, still lacked a solution to recover phosphorus directly from sludge. This gap was filled when a magnetic separation of vivianite was developed by TU Delft and Wetsus. This new ViviMag® technology is today owned by Kemira and is currently piloted with Waterschapsbedrijf Limburg and Royal HaskoningDHV at Hoensbroek wastewater treatment plant. We are excited to present some results and tell you more about this trial!
