500 ml of wastewater sample was collected and 200 ml of this sample was analyzed by classical 5 day BOD test (at 20\deg C) with 1/15 dilution. The initial DO measurement result was 9 mg/L and 35% reduction in DO was observed at the end of the experiment. The BOD reaction rate constant was 0.24 d¹ (base e) and there was no change in the DO concentration of the blank. If this wastewater contains 2.35 mg/L ammonia, 0.073 mM nitrate, 0.66 mg/L. nitrite and 7.81 mg/L TKN, answer the following questions:a) What are the organic nitrogen and total nitrogen concentrations in this sample?b) Calculate the BOD, at 10\deg C.
