The present invention provides a process and an apparatus which will greatly reduce the amount of emitted ammonia and odour from in particular animal stables by a process which is both efficient, reliable and relatively inexpensive to carry out, and which at the same time removes ammonia to a concentration of 0-2 ppm and the odours to a level of insignificant inconvenience in the ventilation air of a typical pig or poultry stable.
