The mean oxygen demand is the test done to indirectly determine the amount of organic compounds present in a water sample.
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)
Its full form is biological oxygen demand.Answer:The 5 day Biological Oxygen Demand (BOD5) is a measure of how much biologically usable dissolved organic material is present in a water sample. The units used are mg/liter (mg/L). The material can be eaten up bu microbes which remove oxygen in thee water. If this happens the low oxygen levels in the water make it unusable and or hazardous to fish.BOD5 is measured by putting a sample of the contaminated water in a sealed container, oxygenating it, then adding a microbial culture. The level of oxygen is measured at the end of 5 days and the concentration of organics is calculated.Companion tests include Chemical Oxygen Demand (COD) and Total Organic Carbon (TOC)
Nitrifying bacteria play a crucial role in the BOD (Biochemical Oxygen Demand) test. They are responsible for oxidizing ammonia to nitrate in the presence of oxygen. This helps determine the amount of biodegradable organic matter in a sample, as the oxygen is consumed during this process. By measuring the decrease in dissolved oxygen, the BOD test provides an indication of the organic pollution level in water.
Fire demand is the amount of water required to extinguish fire.
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.
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 .
The mean oxygen demand is the test done to indirectly determine the amount of organic compounds present in a water sample.
There is an increasing demand for Organic foods because people have learned that it is healthier than food grown with pesticides, so it is in high demand for healthier food.
It determines the amount of dissolved oxygen that is consumed by aerobic biological microorganisms in water. It is measured by the amount of oxygen that is consumed per liter of sample during 5 days of incubation it is in milligrams.
yes, because supply is limited and the demand is high then pretty much the price will be affected. since the shortage of supply, and high demand, then price will be high price and very expensive
Biological Oxygen Demand
need basic biological natural drink, shelter want preference demand ability & wilingless to pass
if goods are used together, increased demandfor one will increase demand for the other
Dissolved Oxygen
the demand increases is the wrong answer
the demand increases is the wrong answer
