In BOD reaction p is

• dilution factor

• a constant

• mixing factor

• none of these

expression of p is

• p= total volume of solution

• p = volume of waste water

• p = volume of waste water / total volume

• none of these

The correct relation between BOD, COD and TOD is

• TOD > BOD>COD

• TOD>COD>BOD

• BOD>COD>TOD

• COD>BOD>TOD
