This paper reports on the potential impact on the clarified water quality produced by a dissolved air flotation (DAF) plant, designed and built on the basis of conventional rates (i.e. ~10 m/h Net, excluding recycle) and assessing, when using the same structures loaded at higher rates, whether the product quality may change or online monitoring such as turbidity may be affected. The assessment has been based on the use of both computational fluid dynamics (CFD) and a small number of full scale site trials. Includes 11 references, tables, figures.
