Novel process for removal of dissolved gasses from RAS water

Offentlig prosjektsammendrag

AKVA Group is a leading developer of products tailored for Recirculating Aquaculture Systems (RAS) and the Zero Water Concept (ZWC). While traditionally focused on smaller-scale operations and smaller fish sizes, market shifts now demand support for extended on-land post-smolt and grow-out phases, requiring advanced water quality and dissolved gases management for larger biomass. In RAS environments, dynamics of dissolved gases like oxygen consumption and CO2 release are crucial. As biomass increases, oxygen levels drop while CO2 and dissolved nitrogen rise, necessitating enhanced oxygenation and degassing. Of particular concern is hydrogen sulfide (H2S), a toxic microbial byproduct linked to fish mortalities. To address these challenges and align with EU's Green Deal, AKVA Group's project aims to surpass current standards by enhancing gas removal efficiency and reducing energy consumption. Through process innovation, our goal is to set new industry benchmarks for safe and environmentally sustainable fish production.
