Alumichem receives grant for wastewater treatment project

Alumichem AS, in partnership with DTU Aqua, Clean Matter, and Drying Matter, has been awarded the second largest Green Development and Demonstration Program (GUDP) grant for their fish farming wastewater treatment project. 

NAPRAS – effective Nitrogen and Phosphorous removal in Recirculating Aquaculture System – aims to develop and demonstrate a consolidated treatment system that reduces emissions of nitrogen in the forms of nitrate, nitrite, nitrous oxide, phosphorus, and heavy metal contaminants in RAS. 

The Danish GUDP supports green and innovative projects across the Danish food sector.

Alumichem’s project aims to develop and demonstrate a consolidated treatment system that reduces emissions of nitrogen in the forms of nitrate, nitrite, nitrous oxide (greenhouse gas) and phosphorus, as well as heavy metal contaminants in RAS. 

“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,” said 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.” 

The treatment implements granulated sludge technology alongside Phosphorus precipitation; wet electrochemical removal of heavy metals; enrichment of Phosphorus bioavailability, and finally drying to effectively remove over 95 per cent of nitrogen and capture over 95 per cent of phosphorus into a granular safe fertilizer product.

Alumichem said it is excited to lead this project with the involved parties to continue to drive innovation with wastewater treatment and sludge management of RAS.
