Use of flocculants -high-molecular synthetic water-soluble polymers, is one of the most perspective and economical methods for purification of the return and waste waters from coal preparation plants, and intensification of the whole coal processing process. For efficient use of flocculants, it is necessary to prepare homogeneous aqueous solutions, for which an optimal mixing mode should be selected, taking into account energy costs and quality of the concentrated solution. The paper presents herein result of the homogenization process analysis at preparation of solutions used for slurry water purification. Based on study of the rheological solution behavior and determination of the required for the numerical analysis of the process parameters of the rheological constants, power costs, homogenization time, type of equipment and mixing device have been determined.
