In a wastewater treatment plant, nitrification refers to the oxidation of ammonia by aerobic a microorganisms in an aerated tank. In a particular plant, nitrification proceeds in a 450,000- liter CMFR, removing ammonia with a first-order rate constant k= 1.8 d:!. The flow through the CMFR is 3.2 million liters per day, and the ammonia concentration entering the reactor is usually about 29 mg/L. Then some loser dumps loads of ammonia down the drain, and a shock of 2000 g of ammonia enters the reactor all at once. a. Before the shock, what was the steady-state concentration of ammonia flowing out of the CMFR? b. Immediately after the shock of ammonia enters (and is mixed into) the CMFR, what is the ammonia concentration in the reactor? c. Using your answer to part (b) as the initial concentration, plot (using a computer, not by hand) the ammonia concentration in the outflow during the first 24 hours after the arrival of the ammonia shock in the CMFR
