ABSTRACT
This paper presents the research of the sedimentation process of suspension coal
assisted with flocculation in the multiflux system. The aim of the coal sedimentation
investigation is the evaluation of the influence of the individual techniques of
sedimentation intensification on the effectiveness of the sedimentation process:
flocculation process, use of multiflux fillings, and simultaneous application of both
previously mentioned methods. The research presents the impact of the simultaneous use of both intensification techniques to increase the values of sedimentation rate and compression level of the suspension. Tests were carried out for different doses of flocculant. The process was carried out in the laboratory that imitated (simulated) multiflux sedimentation and a conventional system without the multiflux filling. The results presented within this paper are obtained from experiments done in the static system, as well as from the measurements in the flowing system. Research have shown the validity and effectiveness of the simultaneous application of multiflux sedimentation and flocculation.

Keywords: sedimentation process, coal suspension, multiflux filling.
