| Description
| - The paper deals with the dependence of aggregate properties on the shear rate (G) at steady state. Aggregation of natural raw water and ferric sulphate was carried out in a laboratory Taylor–Couette reactor (TC) and continuous flow mixing tank (MT) with a paddle stirrer. Shear rates in the range of 20–350 s -1 were used.Methods of image and fractal analyses were used to determine the aggregate size and structure, respectively. It was found that the aggregate size decreased with increasing shear rate. There was a small difference in sizes of aggregates formed in TC and MT at G< 150 s -1, but at higher shear rates, almost no difference between TC and MT was observed. The D2 fractal dimension increased with increasing shear rate indicating that aggregates became less porous andmore compact. Moreover, a very closematch in D2 valueswas attained for both mixing devices. The Dpf fractal dimension decreased with increasing shear rate meaning that aggregates were more regular at higher shear rates, but jagged on the surface with irregular shape at lower shear rates. In contrast to D2, aggregates formed in MT were much more irregular (jagged) than those formed in TC.
