P-Campus-Ringvorlesung wird fortgesetzt
Am 16. September findet der erste Vortrag der P-Campus-Ringvorlesung 2021 nach der Sommerpause statt. Jonathan Schleyken von der Universität Rostock referiert zum Thema "P-Recycling in landgestützten Aquakultursystemen". Die Vorlesung beginnt um 15:00 Uhr.
In 2019, the project ‘P-recycling in animal husbandry’ was launched by the Leibniz ScienceCampus Phosphorus Research and the University of Rostock to investigate possibilities for the reduction of nutrient waste in recirculating aquaculture systems (RAS). Luo et al. (2010) demonstrated that depending on parameters such as feeding strategy, feed composition and fish size up to 60% of the provided phosphorus ingested by yellow catfish (P. fulvidraco) was excreted. In this context, the solid P fraction is of particular importance as it can be easily extracted via filter units. In order to reduce the loss of excess P a wet chemical Phosphorus recovery technology was developed to extract Phosphorus from RAS sludges with focus on MCP and DCP as recyclates. The seminar will introduce the applied methods in comparison with different technologies, conducted trials, analytical procedures and ideas for the future development of this project.
