WebAt a BOD:N ratio of 100:4.9, ammonium discharge was significantly greater (1.8 mg/L) than at the lower nitrogen levels (0.04 - 0.18 mg/L). Phosphorus behaviour was more variable, however significantly more phosphorus was discharged at the lowest nitrogen level than at the highest (p<0.05). WebThe free ammonia value is useful in determining the amount of free chlorine needed to increase the monochloramine residual at a booster station. The free ammonia level can be reduced by adding free chlorine at a ratio of 5:1 as Cl 2 :N to guide the process and help minimize nitrification potential. Total Ammonia
