Experiments investigating the use of peracetic acid as a RAS water disinfectant

Presented by Chris Good, director of research at The Freshwater Institute

This presentation highlights a number of Freshwater Institute studies on peracetic acid (PAA) and its application as a water disinfectant in recirculating aquaculture systems. Initial studies included examining PAA to prevent post-vaccination saprolegniasis in Atlantic salmon, and the comparison of semi-continuously applied PAA in RAS with previous research findings on ozone. Follow-up studies included examining both the toxicity of PAA to various life-stages of Atlantic salmon and the bactericidal efficacy of PAA against a range of pathogens in RAS water. Finally, the impacts of low-dose PAA application on fluidized sand biofilter performance is briefly discussed.
