ABSTRACT
In this study, the flocculation of marble powder suspensions was investigated depending on polymer type and dosage. Polyacrylamide was used as a synthetic polymer while starch was used as a natural polymer. The effect of polyacrylamide type was also examined using anionic, cationic and non-ionic polyacrylamides. The flocculation of suspensions was ascertained by turbidity measurements. It was found that anionic and especially non-ionic polymers flocculated the marble powder suspension more strongly than starch and cationic polymer. On the other hand, it was observed that the sequential addition of the starch and polymer did not improve the flocculation of suspension. On the contrary, sequential addition of flocculants caused the re-dispersion of the flocculated suspension. When non-ionic polymer was used as a flocculant, the reached minimum turbidity of suspension was measured to be 38 NTU (nephelometric turbidity unit).
