Waste water = WW pollution, amount of sewage, determination of pollution, self-purification of surface water, principles (processes) of waste water treatment, mechanical and biological treatment (aerobic and anaerobic), sludge management, examples of typical equipments and types of various waste water treatment plants = WWTP (mechanical + aerobic + anaerobic; mechanical + anaerobic + aerobic).
Renewable sources of energy, places of emissions origin, methods and equipments of emissions reduction. Mechanical waste gases cleaning (dust etc. separation) = dry and wet separators, filters, electro-filters. Processes and equipments for harmful gaseous substances collecting and treatment (SO2, volatile organic compounds ...).
