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.
BOD is otherwise known as biochemical oxygen demand. It is important to water quality because it decreases the amount of oxygen to kill bacteria.
BOD loading rate is the amount of organic matter added in water or waste water for example sewage water
183.48
0.7 kg of BOD and 1.4 kg of COD
When diluted water is added in surface wastewater to take immediate BOD is called unseeded and after 5 days of period wastewater received saturated oxygen from diluted water is called now seeded BOD.

BOD (biological oxygen demand) is a measure of the amount of oxygen needed bymicrobes to break down the organic matter in a sample of water. DO (dissolved oxygen) is the amount of oxygen dissolved in the water. When BOD is high, it means there's a lot of organic contaminants in the water, and the microbes are working overtime to break it down. They use up oxygen while doing this, so when BOD is high, DO is low. When the microbes finish breaking down the organic contaminants, their numbers drop from lack of food (a lower BOD). DO usually goes back up again
Biological Oxygen Demand
It is usually of five days but it may either be 3 days depending upon the the BOD test.
BOD5 for tap water are usually 0 ppm,
water retention in bod is called as cites. The only way to get rid of water retention in bod y is to take homeopathic medicine from some expert homeopath.Allopathic medicines can only suppress the symptoms and many lead to more dangerous situation.
Bod - series - was created in 1975.
