The following article is a continuation of research that examines the problem of utilization of phosphorus-containing sludge that is produced in the phosphorus industry. Using models for coagulation and coalescence of the sludge, both within its hydraulic mix and following sedimentation in a ribbon mixer apparatus, very important parameters were identified. Those parameters are: the “energetic barrier” of the coalescence, power that is spent on mixing dispersed particles of sludge in conditions of complete coalescence, duration of coalescence, duration of sedimentation of particles of various aggregates and volume of liquid phosphorus that is secreted out of the sludge. Within the coalescence process we identified the prevailing impact of upper particles energy and mixing energy. Using a concrete example, we determined that during mixing and sedimentation, both the production of concentration and the average volume of the produced aggregates of particles is constant.
