##### Reference no: EM132234491

Question 1. Demonstrate that in a Modified Ludzack-Ettinger (MLE) Process for nitrogen removal, the efficiency of total nitrogen removal is a function of the internal recycle rate and of the return activated sludge (RAS) flow rate. You can assume that the efficiency of nitrification is 100% in the aerobic stage and that the efficiency of denitrification is 100% in the anoxic stage. Indicate any other assumptions you make.

Question 2. Based on your analysis of part 1, what is the total nitrogen removal efficiency if the internal recycle rate is 3 times the influent flow rate and the RAS flow rate is half of the influent flow rate.
