Determine whether or not there is sufficient alkalinity for nitrification of the extended aeration oxidation ditch at Brooklyn ( Problem 16-33 ). Compute the mass per day of sodium bicarbonate to add if alkalinity is required. Assume a residual of 80 mg/L as CaCO₃ is required to maintain the pH.

Problem 16-33

Estimate the volume of an extended-aeration oxidation ditch for carbonaceous BOD oxidation and nitrification for the city of Brooklyn using the following design data:

Assume the MLSS = 3,000 mg/L, MLVSS = (0.75) MLSS, and typical kinetic coefficients in Tables 16-14 and 16-5 apply.
