oxygen required for a biological decomposition of dissolved solids or organic matter in waste water under aerobic condition at standard temperature is called
Answers
The total amount of oxygen that is required for a biological decomposition of dissolved solids as well as organic matter present in waste water and being subjected to aerobic conditions at some standard temperature, is known as Biochemical oxygen demand i.e. BOD.
This can be studied in detail in connection to that relate to "Waste Water Engineering".
This process might also consider certain waterborne solids or liquids also.
Hence BOD is expressed in terms of kilograms or oxygen in one litre/liter of any matter after it has been treated for a temperature of 20 degree Celsius for 4-5 days under incubation.
Answer:
Biochemical Oxygen Demand (or BOD) is the amount of dissolved oxygen needed (i.e. demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period.
BOD reduction is used as a gauge of the effectiveness of wastewater treatment plants. BOD of wastewater effluents is used to indicate the short term impact on the oxygen levels of the receiving water.
