Biochemical Oxygen Demand is the measure of the amount of oygen consumed by microorganisms in decomposing organic mattter in water bodies.
BOD directly affects the amount of dissolved oxygen in water-bodies (i.e. rivers and streams). The greater the BOD, the more rapidly oxygen is depleted in the stream.

What is a biological oxygen demand?
A biological oxygen demand is another term for a biochemical oxygen demand - the amount of oxygen needed by aerobic microorganisms to decompose all the organic matter in a sample of water - used as a measure of pollution.
What is the significance of BOD and COD in water quality management?
Biochemical oxygen demand (BOD) and chemical oxygen demand (COD) both measure the quantity of organic compounds found in water. The makes them significant when is comes to the treatment of water.
What is allylthiourea used for?
Biochemical oxygen demand, BOD. Cuger Brant
What is a full form of BOD?
In chemistry b.o.d means " biochemical oxygen demand "
What are the effects of low biochemical oxygen demand?
good qualitywaater good quality water
What is biochemical oxygen demand of Jaggery solution?
1kg Jaggery = 1kg BOD
What businesses offer biochemical oxygen on demand?
Some of the chemical companies offer biochemical oxygen on demand would be the Myron L Company, Mantech, Environmental Services by Daniel L. Theobald, Ovivo, Westech Engineering, and Cleveland Biotech Ltd.
Define the term cod and bod?
"COD" is Chemical Oxygen Demand," and BOD is Biochemical Oxygen Demand." These are the two processes that cause oxidation of an object in either a natural waterway or in industrial wastewater..
How does the temperature of water effect the dissolved oxygen?
Well, dissolved oxygen impacts water quality because if the level of the dissolved oxygen is too low then organisms can die. _________________________________________________________________ That is okay, but I want to what dissolved oxygen tests for. ------ For the water quality are tested: - total oxygen demand (TOD) - biochemical oxygen demand (BOD) - chemical oxygen demand (COD) - sometimes, carbonaceous biochemical oxygen demand (CBOD) For details about the analytical procedures I recommend you to read a book or a collection of analytical methods for water, searching in a library or searching on the Internet.
What is the principle of chemical oxygen demand?
Chemical Oxygen Demand (COD) is a labortory test to give a measure of the amount of reactive organic materials in a sample of water. Like the five day Biochemical Oxygen Demand (BOD5) it demonstrates the amount of organics present by how much oxygen they consume over a period of carefully controlled conditions (the starting and ending oxidant concentrations are measured and the temperature is controlled)
What is the importance of BOD in water quality management?
BOD is otherwise known as biochemical oxygen demand. It is important to water quality because it decreases the amount of oxygen to kill bacteria.
What is the different between biochemical oxygen demand and biological oxygen demand?
Oxygen Demand -The amount of oxygen require to oxidize an organic materialBiochemical (Biological) Oxygen Demand (BOD) -The amount of oxygen required to oxidized any organic matter present in the water by microbes present in the water. Usually representin the easily "digestible" organics.Chemical Oxygen Demand (CO) - The amount of oxidants experessed as oxygen required to consume all organics in a water sampleTotal Oxygen Demand (TOD) the sum of COD and BODBiological Oxygen demand is the oxygen required to oxidized only organic matter by micro organisms (it is basically a prototype of actual process happening in treatment plant) while chemical oxygen demand is the oxygen consumed to oxidize all organic and inorganic matter and it employ chemicals to do this process that why it is way more fast then BOD experiment .
