Inactivation of biofilms formed under high shear stress on various hydrophilic and hydrophobic surfaces by a continuous flow of ozonated water.

The inactivation of biofilms grown on glass under high shear stress and exposed to a range of dissolved ozone concentrations (2, 5 and 7 ppm) at 10 and 20 min was investigated. The regression equation, log reduction (biofilm) = 0.64 + 0.
