1. 2. An industrial wastewater is known to contain stearic acid (C18H3602), glycine (C2H5O2N), and glucose (C6H12O6). The results of laboratory analysis indicate that organic nitrogen = 12 mg N/L, organic carbon = 130 mg C/L, and COD = 425 mg/L. Determine the concentration of each of the three constituents in mg/L. Useful molecular weights: C-12, H-1, N- 14,0-16 ) In class, you have been given that there is 1.42 mg COD per mg VSS. Prove that this is the case by calculating the ThOD of biomass. Assume biomass has a chemical formula of C5H7O2N on average. Useful molecular weights: C-12, H-1, N-14, 0-16
