NAPRAS fish farming wastewater treatment project. Alumichem A/S in partnership with DTU Aqua, Clean Matter and Drying Matter announced it has been awarded the 2nd largest (2nd application round 2023) GUDP grant for their NAPRAS – Effective Nitrogen (N) and Phosphorous (P) removal in Recirculating Aquaculture System (RAS) fish farming. The aim of the project is to develop and demonstrate a consolidated treatment system that reduces emissions of N in the forms of nitrate, nitrite, and nitrous oxide (greenhouse gas) and P, as well as heavy metal contaminants in RAS. The treatment implements granulated sludge technology alongside P precipitation, wet electrochemical removal of heavy metals such as Zn, Cd, and enrichment of P bioavailability, and finally drying to effectively remove >95% of N and capture >95% of P into a granular
safe fertiliser product. Alumichem is excited to lead this project with DTU Aqua, Clean Matter and Drying Matter to continue to drive innovation with wastewater treatment and sludge management of RAS in Aquaculture.

“DTU Aqua, Clean Matter and Drying Matter have been strong partners for us, and we are always happy to execute on innovative and potentially disruptive projects with them,” says Christian Bang-Møller, Chief Technology Officer at Alumichem. “This is an exciting innovation project because we are seeing the environmental discharge limits within RAS become tighter and more complex and we want to be there to support our current and future clients.”
