Chemical air washer, how does it works?

An air washer is designed to prevent emission of ammonia from the stable to the outside air. An excess of ammonia deposition can lead to acidification of the environment. This acidification not only disrupts the ecosystem, it also affects the soil and is harmful to health. Within the development of low-emission stable systems, the air washer takes a particular position. In recent years, the air washer has been very popular. 

because of the high reduction rates (70-95%) in ammonia. In unlike other low-emission stable systems, an air washer is not a low-emission housing system. An air washing system is an ‘end-of-pipe’ technique, whereby the air from the stable is going through a filter package and will be cleaned. There will be nothing changed for the penning design inside the stable. This also means that there is no positive effect on the climate inside the stable, but on the out-going air.

The purpose of stable air treatment in livestock farming is primarily to removing ammonia. Besides ammonia (depending on the type of air washer) other components are removed from the air, such as odor and/or or (fine) dust. Reducing the emissions of these substances contribute to improve the quality of the air and the environment
