Biochemical Oxygen Demand (BOD) is commonly used for determining how fast biological organisms use up oxygen in a body of water. It is one of the essential methods used in water quality management and assessment. BOD could be considered as a quality level indicator of biologically treated water. This process is very time-dependent but most common period of incubation is five days - BOD(5). In this thesis different periods of incubation are compared - for BOD(5) with five days incubation period and BOD(2+5) with five days incubation period but also placed for two days to lowered temperature environment. These comparative tests were made for different types of water (surface water, waste water - water from mechanical level and biological level of treatment) For all kinds of determination of BOD the dilution method was used (ČSN EN 1899).
