Subject aims expressed by acquired skills and competences

The goal is to master the physical-chemical hydroseparation process called flotation, both in theory and in practical terms. Flotation can be used for treatment of municipal and industrial water and drinking water during treatment.

Summary

Theoretical premise of flotation (thermodynamics of elementary flotation), physical, chemical and electrochemical characteristics of interface of phases in connection with mechanism of hydrophobisation of solid phase. Modification of flotation options for separating of mineral raw materials, industry waste and waste water. Type flotation devices, regenerative modes and technological diagrams.
