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

What are the relationship between cod chemical oxygen demand and bod5 biological oxygen demand what does the ratio of bod cod or cod bod means?
The relationship between COD and BOD5 is that COD measures the total organic matter in water, while BOD5 measures the amount of oxygen required by microorganisms to biologically degrade organic matter. The ratio of BOD/COD or COD/BOD can indicate the biodegradability of organic matter in water; a high ratio suggests that the organic matter is easily biodegradable, while a low ratio indicates it is less biodegradable.
What is the relationship between bod and organic matter?
BOD (Biochemical Oxygen Demand) measures the amount of oxygen required by microorganisms to decompose organic matter in water. Organic matter contributes to BOD levels as it serves as a food source for microorganisms, leading to oxygen depletion in water bodies. Therefore, higher levels of organic matter can result in increased BOD, impacting water quality and aquatic life.

What are the differences between seeded and unseeded BOD?
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.
