Question

Which statement is the most correct concerning biochemical oxygen demand (BOD)?why?

(A)

Carbonaceous BOD is associated with organic matter, and nitrogenous BOD is associated with ammonia.

(B)

Carbonaceous BOD is associated with organic matter, and nitrogenous BOD is associated with biomass.

(C)

Carbonaceous BOD is associated with suspended solid matter, and nitrogenous BOD is associated with ammonia.

(D)

Carbonaceous BOD is associated with suspended solid matter, and nitrogenous BOD is associated soluble matter.

Explanation / Answer

option(A) is correct because

CBOD is a method defined parameter is widely used as an indication of the pollutant removal from waste water. Carbonaceous biochemical oxygen demand (CBOD) is a method defined test measured by the depletion of dissolved oxygen by biological organisms in a body of water in which the contribution from nitrogenous bacteria has been suppressed.
