Control of ammonia emissions with biofilters and bioscrubbers


, : Control of ammonia emissions with biofilters and bioscrubbers. Volatile emissions from livestock farming and sewage operations Proceedings of a workshop, Uppsala, Sweden 10-12 June 1987: 196-208

Biofilters and bioscrubbers are relatively low cost methods for reducing ammonia emission from the ventilated air produced by livestock buildings. The principles of the systems are explained and specifications tabulated for bioscrubbers for fattening pigs and fattening calves, and biofilters for drying poultry manure and pasteurisation of compost for mushroom production. Results of measurements taken from these treatments are presented and the actual processes involved are explained.
