Ammonia removal from wastewater
Ammonia removal from wastewater
(OP)
Wastewater contains 1000-5000 mg/l NH3, and must be reduced to <10 mg NH3/l for discharge. What methods are available? Raising pH and air-stripping is one obvious solution, but then the off-gas will have to be oxidised to remove the ammonia gas and this will require fuel, scrubbing and recycling. The wastewater is in a large tank. Can it be treated in situ?

1. Combined carbon oxidation nitrification/denitrification in suspended growth reactor using endogeneous carbon source.
2. Combined carbon oxidation nitrification/denitrification in suspended growth using waste carbon source.
3. Suspended growth using methanol following a nitrification stage.
4. Attached growth (column) using methanol following a nitrification stage.

You have a fairly concentrated source of NH3. Do you have enough volume of wastewater to economically recover the NH3 and sell it or make other products?

Other way is steam stripping, in a column with a short rectification section, to obtain amoniacal solution, i.e., 25 - 30%
