Abstract: This dissertation was inspired by a work done by Parini and Pitt (2006) on the effects of the impingement of equilibrium bubbles on the removal of dental plaque. It was felt that a comprehensive study on the characteristics of surface contaminant attachment and removal with respect to bubble impingement and ultrasound had to be conducted so as to study the feasibility of their use in industry. To do so, a wide range of investigations was carried out, including the effects of shear and surface roughness on algae deposition on solid substrates, the effects of ultrasound on algae biofilms, and the effects of bubble impingement on algae biofilms. The results do not support the feasibility of using either ultrasound or bubble impingement or even both of them together for an efficient and effective removal of surface contaminants.
