Het effect van een chemische luchtwasser op de ammoniakemissie uit een vleesvarkensstal

Commissioned by Bovema Inc. in Milsbeek (NL), the Research Institute for Pig Husbandry investigated the chemical scrubber as a means of reducing ammonia emission from growing-finishing pig houses. The scrubber is supposed to absorb ammonia from ventilation air into a acid solution. The acid fluid is sprayed onto a plastic filter medium, which is placed in the ventilation flow of the pig house. In pig husbandry air scrubbing is mainly applied in central extraction systems, which are often applied in new buildings. The principal aim of this research was to determine the reduction in ammonia emission from the growing finishing pig house where pigs are housed according to law regulations as to animal welfare in 199
