Technology description

Ammonium (NH4+), present in manure and digestate, is in balance with ammonia (NH3), which is volatile. Under the influence of pH and temperature, the ratio of ammonia to ammonium can be increased so that the ammonia nitrogen can volatilize more quickly.

By blowing in air, the volatile ammonia is removed from the liquid fraction and the nitrogen (N) can be recovered.
