Funding initiative aquaculture of the Deutsche Bundesstiftung Umwelt: „Biological sewage purification by the integrated culture of halophytes in landbased marine recirculating aquaculture systems for fish culture (first phase)”


The project focuses on the biological sewage purification in landbased marine recirculating aquaculture systems (RAS) by the integrated culture of salt-tolerant plants (halophyte) in artificial wetlands.


This joint project is led by Erwin Sander Elektroapparatebau GmbH in cooperation with the University of Hannover and the University of Technology and Economy Saarland (HTW). The development of sustainable processes in sewage purification for aquaculture systems is investigated. Despite continuous development in the field of water treatment technology of modern RAS, the removal of solid matter still leads to non-optimized rates of water withdrawal. Moreover, the released water also includes high loads of nutrients. Those nutrients shall be reused by the halophyte culture so that nutrient-free water can be returned to the aquaculture systems.


In experiments with the salt-tolerant plants Salicornia europaea, Aster tripolium und Plantago coronopus the nutrient retention and quality of the plants are investigated.
