dc.description.abstract The research developed a UV Taylor Couette reactor for disinfecting milk as a model opaque fluid. The principal of the reactor was to generate laminar vortices to support efficient mixing and homogenous UV photon distribution. The UV reactor parameters were optimized to generate laminar vortices that were stabilized by modification of the unit with baffles. A model was developed to predict the UV dose required to inactivate model microbes in milk. Through verification trials it was noted the predicted UV dose underestimated that required to support a 5 log cfu reduction of microbes. It was subsequently identified that the deviation from predicted values could be attributed to fat content that enhances the UV inactivation of microbes in milk with proteins providing protection to microbes. In conclusion, the UV Taylor Couette reactor has strong potential for disinfecting opaque fluids although matrix effects need to be considered when undertaking validation trials. en_US
