A series of flocculation tests were performed to investigate the effect of low-shear rates (G = 3-16 s(-1)) on flocculation of kaolin suspension by polyaluminum chloride (PACl), with the goal of understanding floc growth mechanisms. Results were reported in terms of floc average size (d(p)) and boundary fractal dimension (D(pf)), derived from a non-intrusive optical sampling and digital image analysis technique. As expected, the rate of floc aggregation increased with increasing G, resulting in… CONTINUE READING
