This paper presents the research on the sedimentation process assisted with coagulation process. The main purpose of this project is to determine the method of coagulant dose selection during the sedimentation of the coal suspension. Measurements have been made for various sedimentation intensification techniques: the use of coagulant, the use of lamella, and the use of both techniques simultaneously. The efficiency of the sedimentation process was compared using various intensification techniques. The studies wer...

The paper presents a proposal for validation of a numerical model of a sedimentation process with use of a flow system. The essence of the proposed solution is to verify the numerical model using quantitative data, expressed by the flow rate and concentration of the suspension at the input and output of the device, as well as the qualitative data describing their granulometric composition. The analysis was carried out using a laboratory settler, as a sedimentation device, in which, during the purification process ...
