Abstract
The purpose of this study was to investigate factors influencing sludg e thickening in the dissolved air flotation process. Attention focused on the alteration of sludge characteristics as a result of coagulatio n and aeration. Batch thickening experiments showed that both coagulat ion and aeration enhanced sludge thickening. The most important parame ter influencing sludge thickening appeared to be sludge particle size; larger particle sizes produced higher sludge solids concentrations in the float.
