Alumichem, along with partners, has secured a Green Development and Demonstration Programme grant for the NAPRAS fish farming wastewater treatment project Collaborating with DTU Aqua, Clean Matter and Drying Matter, the NAPRAS initiative aims to revolutionise wastewater treatment in recirculating aquaculture systems (RAS). The project focuses on efficient nitrogen (N) and phosphorous (P) removal, aiming to reduce emissions significantly. The innovative treatment involves granulated sludge technology, P precipitation, wet electrochemical removal of heavy metals and a drying process, achieving more than 95% removal of N and capturing over 95% of P. The collaborative partnership seeks to address tightening environmental discharge limits in RAS.
