Electrochemical Oxidation in the Recirculating Aquaculture Systems Industry (ELOXIRAS)

ELOXIRAS was a three-year project funded by EU Horizon 2020, aimed at developing an innovative process for the treatment and reutilization of marine and brackish water in recirculating aquaculture systems (RAS) in order to enhance the productivity and reduce the environmental impact of aquaculture activities. 

Tangible results: The project created water-treatment systems for RAS (namely ELOXIRAS® HYBRID, ELOXIRAS® MINI, ELOXIRAS® LOGISTIC, ELOXIRAS® BIO), which constitute a controlled setting to optimise production growth and fish survival and increase the efficacy of removing pollutants from the water. Due to the selective oxidation reactions promoted, the technology allows attaining high removal rates of most concerning contaminants, such as TAN, nitrite and dissolved organic matter, also presenting high disinfectant efficacy.

Application/relevance: The ELOXIRAS® technology has been subjected to validation tests under real operating conditions in marine fish hatcheries and marine fish growing farms to corroborate the efficacy of the system in terms of pollutants remediation and to demonstrate its applicability to end-users.
