Ecotoxicological assessment of UV-C/Oxidant processes for advanced treatment of aquaculture effluents
and NaClO resulted in significant adverse effects on its survival. This is likely due to residual oxidants and DBPs, as dark controls showed lower toxicity, and UV-C alone had a negligible effect. For P. subcapitata bioassays, UV-C/PMS and UV-C/PS were identified as the most suitable treatments. Our findings support the use of UV-C-based AOPs for aquaculture effluent treatment, with prudent selection and addition levels, while highlighting dilution via recirculation in recirculating aquaculture systems (RAS) as an intrinsic advantage for mitigating relevant ecotoxicological risks.
