Organic carbon (C) and ammonia nitrogen (NH3) are oxidized to carbon dioxide (CO2) and nitrate (NO3-) respectively, by bacteria that are naturally present in wastewater and in natural systems such as lakes and rivers. Both of these reactions consume oxygen and may cause a negative impact on water quality. The amount of oxygen theoretically required to consume a carbonaceous (ThOD) or nitrogenous (NOD) waste may be calculated according to the stoichiometry of the reactions as outlined in this chapter. The production of coke, a fuel produced from coal for use in steel mills, generates a waste gram rich in ammonia, phenol, and naphthalene. Calculate the NOD and ThOD of a waste containing 25 mg/L of ammonia-nitrogen (NH₃-N), 50 ing/L of phenol (C₆H₅OH). and 150 mg/L of naphthalene (C₁₀H₈). What is the total theoretical oxygen demand of the waste?
