What is TOD BOD in water quality measurement?
There are three OD's used Total Oxygen Demand (TOD), Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD) They all measure the amount of oxygen that would be required to consume organic material in the water, BOD is the lowest (usually) as it measures demand from microbes eating easily digested organics (sugars etc), COD measures the demand from all other organics (alcohols etc) measured by digesting the material in strong chemical oxidants, and TOD is the total of the two. Oxygen demand is important to know in waste handling as reducing the oxygen in receiving stream can harm fish and other aquatic life.
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 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 .
Is oxygen found in the human brain?
Yes. In fact, such is the brain's demand for oxygen that it requires 20% of your total oxygen supply. This explains why it is served by so many blood vessels.
Why is there a demand for chemical oxygen?
There is a very large demand for chemical oxygen. Chemical oxygen is very sought after because it can be used to determine when water is contaminated with pollutants.
What is mean chemical oxygen demand-?
The mean oxygen demand is the test done to indirectly determine the amount of organic compounds present in a water sample.
What is the total demand for money?
According to John Maynard Keynes, the total demand for money is composed of transactional demand, precautionary demand and speculative demand for money.
6 How much is the theoretical oxygen demand of 1mM acetate solution?
The theoretical oxygen demand (ThOD) of acetate is 2 moles of O₂ per mole of acetate. To calculate the ThOD of a 1mM acetate solution, you would convert mM to moles (1 mM = 0.001 moles) and then multiply by the ThOD (2 moles O₂/mole acetate) to get 0.002 moles of O₂.
What is it called when you demand oxygen to muscles?
A yawn
How much of our oxygen does the brain use?
The brain consumes about 20% of the body's oxygen supply, despite making up only about 2% of the body's total weight. This high oxygen demand is necessary to support brain functions such as thinking, memory, and sensory processing.
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 happens in your muscle tissue and cells when the demand of oxygen is not met?
If the demand for oxygen is not met for a long period of time, the cells within the muscle tissue will die.
