Annotation	This paper summarises the preliminary results concerning an influence of the agitation conditions on the aggregation processes. The properties of formed aggregates affecting the efficiency of separation processes are studied as well. The results show that the applied velocity gradient G, the period of its action T and the distribution of velocity field in an agitated volume of water significantly influence the number of aggregates, their size and shape. Smaller and denser aggregates of a homogeneous size and more resistant to breakage are formed under a higher velocity gradient.
