The BOD3 of a wastewater is determined to be 270 mg/L at 20 o The rate constant (k) value is known to be 0.34 per day as first order. (C: 12 g/mol, H: 1 g/mol, O: 16 g/mol) Note: Reaction should be stoichiometricly balanced CH2O + O2 ------> CO2 + H2O (a) What would be BOD5 value if tests were run at 20 oC? (b) What is the concentration of formaldehyde (CH2O) in wastewater?
