UGC NET Environmental Science Mock - 4 - Question 5

Consider the following about the organic strength of wastewater.

1). BOD is the measure of oxygen equivalent to the requirement to oxidizing organic matter

2). This is measured at 20 degrees Celsius in five days

3). It is the most reliable measure out of all the measures including COD and TOC

Select the incorrect code:

Detailed Solution for UGC NET Environmental Science Mock - 4 - Question 5

Statement1. Biological Oxygen Demand (BOD) represents the amount of dissolved oxygen needed by the microorganism in a particular amount of water at 20 degree Celsius in five days.

Whereas Chemical Oxygen Demand (COD) is the measure of oxygen equivalent to the requirement to oxidizing organic matter. Hence it is incorrect.

Statement 2 is correct. Kindly refer to statement 1 for this in explanation

Statement 3. COD is the most reliable of all the tests and not BOD.

Due to the length of time required to complete the BOD5 test (five days), BOD results provide historical data only and do not facilitate rapid water quality assessment for optimal process control. The highly variable chemical composition and strength of industrial wastewater requires a much more rapid method for measuring the organic concentration, hence the use of the two hour COD test
