Determine whether or not there is sufficient alkalinity for nitrification of the extended aeration oxidation ditch at Pasveer ( Problem 16-27 ). 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 16-27

Using the EPA criteria, design a controlled discharge oxidation pond for Coprolite. Coprolite is located in a state where the average winter temperature is 16^oC. The design assumptions are as follows:
