Pioneering research on new ways of phosphorus recovery
Research institute Wetsus has started a new research topic in January 2013 with a special focus on the development of technologies for phosphorus recovery from wastewater. This research theme is financed by STOWA and KEMIRA. Further expansion on the theme is being explored.
Within the research topic, two PhD studies and a feasibility study take place. The first study focuses on the release of phosphorus from ferrous sludge. Struvite recovery from wastewater sludge is currently limited to WTTPs operating with biological treatment. This research takes place at Wetsus by a PhD student at TU Delft under the responsibility of Prof. Mark van Loosdrecht.
The second study focuses on the development of absorbentia having a very high absorption capacity for phosphorus. This research also takes place at Wetsus by a PhD student at TU Delft under the responsibility of Prof. Geert-Jan Witkamp.
Finally, a feasibility study on the recovery of complex phosphorus compounds from bacteria is carried out. Such compounds have a potentially greater added value than precipitates as calcium phosphorus and struvite.
The research theme started January 1st, 2013 and will continue until at least 2017. At present, funding is available for 2 PhD positions. Further expansion on the theme is possible if more companies join the research topic. The participating companies are entitled to patents that are developed within the research and thus can recoup their contribution.
