Computational fluid dynamics (CFD) models of dissolved air flotation (DAF) have shown formation of stratified flow (back and forth horizontal flow layers at the top of the separation zone) and its impact on improved DAF efficiency. However, there has been a lack of experimental validation of CFD predictions, especially in the presence of solid particles. In this work, for the first time, both two-phase (air-water) and three-phase (air-water-solid particles) CFD models were evaluated at pilot…

TLDR
It is found that flotation, in general, is enhanced by the use of larger particles and larger bubbles, and bubble size will have to be increased by a factor of two over the size currently employed in many facilities during dissolved air flotation.
