The paper describes the influence of the global velocity gradient G (in range of 28.4 - 307.2 s-1) on the properties of aggregates (size and structure) formed during a coagulation/flocculation process. Further, it describes the influence of mentioned aggregate properties on separation using depth filtration. It was proved that with increasing G, the aggregates became smaller, more compact and regular (the D2 fractal dimension increased) and the suspension became more homogeneous. The aggregates with the smallest diameter and highest D2 fractal dimension displayed the best filterability, i.e. penetrated throughout the full depth of filter bed and generated a minimum pressure drop.
