Calculate the over all efficiency of a nitrification
process with a target
effluent ammonia
of 0.5 milligrams per
Liter, dissolved
Oxygen
in
the aeration
Tank-of 60 mg/L, aeration
tank pH of 6.5
and the geration temp
of 15°C. Based on the efficiency graphics
the ammonic efficiency is
70% of the
pH efficiency is 57% , and the temperature
efficiency is
25%
