Farm Wet Scrubber

Absorption in water droplets of odours, ammonia and dust from livestock buildings

Background

• Increasing number of large- scale livestock facilities
   
• Intensified demand
   
• Buffer zone requirement of 300m effects 25% of livestock producers.
   
• The total ammonia emission from pig and poultry houses amount to about 32% of the total nitrogen loss from livestock manure.
   
• A large number of odorous components are emitted from livestock buildings.
  
  Demands for the reduction of offensive odour, ammonia and dust emissions from livestock production facilities by people living in the vicinity, as well as by the rest of the society, will be intensified in the coming years. Due to the type of ventilation system widely adopted in Denmark, it is thought that a wet scrubber, which consists of an absorption column in the ventilation stacks and a central water purification module, will be one of the technical solutions to meet these demands. This new concept of a wet scrubber enables flexible installation, and therefore extensive applications can be expected, both to existing and new livestock buildings and in Denmark and other countries.
