WHAT WE DO

Open Innovation

AI aims to provide innovative technology for closed loop RAS systems for the fish farming industry. At Marineholmen Forskningspark under the Ocean Innovation cluster we work along with leaders in development and research in the field such as NIVA and RASLab.

Currently our effort focused on qualification of new technology that will allow for direct electrochemical removal of ammonia (being continuously excreted as part of the metabolism) as an alternative to biofilters, which for a long have provided this critical function achieved by a complex bacterial flora that consume ammonia. The innovation is based on a completely new approach in removing ammonia from so called Recirculated Aquaculture System (RAS) facilities.


In a RAS system, fish can be grown more efficiently with reduced environmental impact. The performance of a RAS system relies almost completely on these biofilter units and any upsets and shift in the composition of the bacterial flora can have dramatic effects on fish health. This is a sensitive operation that requires stringent control of the status of the bacterial flora.  Loss of complete production volumes are not uncommon due loss of control of biofilter processes.

 

THE TECHNOLOGY

Advanced Solutions

Our technology will provide an immediate production capacity available by the turn of a switch, whereas biofilters systems typically need up to 2 months in order to establish the bacterial culture needed. Main benefits and added value are based on: 


  • Significant savings in footprint for new plants and expansion of existing plants.

  • Efficiency increases due operational capacity being immediately available – or as back-up for unforeseen events.

  • Readily available operational capacity during service overhaul

  • Improved oxygen supply, as no oxygen is required by the setup, as opposed to aerobic oxidation of ammonia, i.e., nitrification

  • Decreased risk of biofilter-related H2S production and outbreak


Electrochemical processing of ammonia will provide a major progress and contribution as a vital system component in maintaining consistent water quality. Water quality is considered the most crucial factor in achieving efficient production and good fish health. 


This technology is also relevant for live haul of fish during well boat transport and containment such as during sea lice treatment operations.
