Evaluation of practical technologies for Perfluoroalkyl (PFA) remediation in marine fish hatcheries

Per- and poly-fluoroalklys (PFASs) are now emerging as pollutants with potentially catastrophic impact on aquaculture facilities. Two key research institutes have already demonstrated the presence of PFASs in marine fish broodstock and have observed impacts on offspring. However, understanding of the impacts of PFASs on aquatic species is limited. In order to further assess these impacts, this project will: - assess the effectiveness of ozofractionation and linseed infused polypropylene in the removal of PFAS from seawater; - investigate the impacts of flow rate through fractionation chambers on PFAS removal; and - test fractionation PFA removal efficiency without ozone and with ozone at addition levels compatible with aquaculture practices.
