A number of analyses are conducted on a sample of the effluent of a WWTP which is found to have no organic nitrogen and a TKN of 50 mgN/L. The sample pH measurement says 7.3 and the Partial Alkalinity test results are 550 mgCaCO3/L

i) Estimate the TIC (mgC/L) and free ammonia (gNNH3/L) concentration in the water sample.

ii) At the same pH if ammonia is to be stripped out to the gas phase (assuming no ammonia in the air), if a kLa of 0.8 h-1 can be achieved what would be the daily removal rate of ammonia to gas phase (in mgNNH4/L.d)
