1.0 m 3 /s of wastewater contains 20 mg/L of ammonium ion (as N; NH4 -N). It is necessary to nitrify the ammonium to nitrate
- 1.0 m3/s of wastewater contains 20 mg/L of ammonium ion (as N; NH4 -N). It is necessary to nitrify the ammonium to nitrate (NO3 - )
- a. How many kilograms per day (kg/d) of the ammonium (as N) must be nitrified?
- b. How many kg/d of oxygen is needed assuming all is used for nitrification?
- c. How many kg/d of oxygen needs to be supplied to the treatment system if only 10% of the oxygen in air can be transferred (as DO) to the process?
- d. Using the kg/d determined in part c., what m3/min air rate is needed at 20°C and 1.0 atm if the air contains 23% oxygen by mass?
- pV = nRT Gas constant: R = 8.21 x 10-5 atm·m3 ·mole-1 K-1 Density of air = 1.2 kg/m3
