The aim of this unit is for students to learn about the types of disperse systems, the factors that determine their properties, and about the separation processes. The stability issues of different systems, the role of the interfacial tension, adsorption, and surface forces, and the factors that lead to coagulation, flocculation, or Ostwald ripening are considered.
Special attention is paid to the membrane separation processes, depth filtration, gravity, and inertial sedimentation, as well as the separation methods for aerosols. In addition, the unit introduces students to basic concepts such as separation efficiency, particle size distributions, coagulation kinetics, the use of surfactants to modify the surface properties of dispersed particles, etc. The lab practice illustrates the lecture material and gives a visual idea of the studied systems and processes.
