Wastewater Treatment:
Main chemical-physical characteristics of the water and the methods of measurement: temperature, electrical conductivity, color, flavor and odor, turbidity, ionic and dissolved gas analysis, pH, alkalinity, water-hardness, self-cleaning power of watercourses, principles of decomposition of organic substances, BOD, COD, TOC.
Wastewater treatments: screening, sandblasting, de-oiling, biological filtration, treatment with activated sludge, sludge treatment and disposal, chemical treatments: coagulation and flocculation, filtration, demineralization, electrodialysis, degassing, disinfection.

Air:
main gaseous and non-gaseous pollutants and their classification;
Reduction of combustion emissions (CO, NOx, SOx, Hydrocarbons); absorption and adsorption systems.
Particulate reduction systems: sedimentation chambers, impact separators, cyclones, venturi filters, water separators, bag filters, electrostatic filtration.

Waste:
General and classification.
Main industrial treatments aimed at recovery and recycling: comminution (crushers, shredders, impact machines), screening, classification, separation according to the different physical properties: Wemco machine, sieves, separation with boards, separation with ion bombardment, separation with currents induced, magnetic separation, impact separation, forced ventilation, optical separation, heat adhesion.
