Subject syllabus:

1. Physico - chemical properties of dispergated suspensions. Electrokinetic slurry properties, electrokinetic potential and stability of suspensions, dispersing agents, the possibility of increasing the stability of suspensions. 2. Flocculants. Division, selective properties of flocculants, adsorption mechanism of flocculants. 3. The mechanism of flocculation, flocculation kinetics, activators, depressants, modifiers in the selective flocculation, selective flocculation physical parameters. 4. The parameters influencing the progress of flocculation and selective flocculation. 5. Practical application of selective flocculation. 6. Flocculation by stages, a combination of selective flocculation with other procedures, application of selective flocculation. Practice: Practical verification of flocculants in sedimentation tests, tests of selective flocculation on selected types of suspensions, the influence of bioflocculants, applications of flotoflocculation.
