This paper deals with packed-type (multicurrent) settlers, which - compared to conventional ones - display a number of advantages. Two experimental stands, viz. with tubular elements and prate packing, have been constructed. Eight kinds of suspensions were tested. The results of investigations of tubular and plate settlers constituted a basis for the determination of sedimentation effectiveness being a function of dimensionless groups. Moreover, the experimental results have served to verify models and calculational methods, quoted in the literature.
