Question

what is biological oxygen demand BOD?​

Answer 1

Answer:

Biochemical Oxygen Demand ( BOD, also called Biological Oxygen Demand) is the amount of dissolved oxygen needed (i.e. demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period

Answer 2

Biochemical  Oxygen Demand (BOD)

Explanation:

• Biochemical oxygen request (BOD) is the measure of broke up oxygen required (for example requested) by oxygen consuming natural life forms to separate natural material present in a given water test at certain temperature over a particular time span.  
• Natural Oxygen Demand (BOD) is one of the most widely recognized proportions of poison natural material in water. Body demonstrates the measure of putrescible natural issue present in water. Thus, a low BOD is a pointer of good quality water, while a high BOD demonstrates contaminated water.  
• Natural Oxygen Demand (BOD) and Water. Biochemical oxygen request (BOD) speaks to the measure of oxygen devoured by microscopic organisms and different microorganisms while they deteriorate natural issue under high-impact (oxygen is current) conditions at a predetermined temperature.  
• A BOD level of 1-2 ppm is viewed as generally excellent. There won't be a lot of natural waste present in the water supply. A water supply with a BOD level of 3-5 ppm is viewed as respectably perfect.  
• The rot of natural issue in water is estimated as biochemical or compound oxygen demand.
• The test for biochemical oxygen request (BOD) is a bio assay method that estimates the oxygen devoured by microbes from the deterioration of natural mettle.
