Poultry production is increasingly regarded as a source of air pollutants which can be environmentally harmful. The air in animal housing contains gases, odours, dust and micro-organisms. These pollutants could directly attenuate poultry health which has major consequences on productivity. Moreover, they could also have a drastic influence on the general health of the people living close to poultry enterprises and the labourers working inside these enterprises. Generally dust can be considered as one of the most important sources for air contamination in poultry houses, where it may be generated from feed, litter, dried manure, feathers and building materials. According to environment protection laws and the maximum acceptable dust concentration in the workplace, dust concentration inside poultry houses must be controlled to provide adequate air for the labourers and the animals inside these buildings.
The aim of this investigation was to increase the air quality by purifying the recirculating air inside the animal barn. The experiments have been done inside laying hen houses with the aviary system. Dry and wet filter techniques have been tested to reduce the indoor dust concentration inside the laying hen houses. Laboratory experiments have been done to select suitable materials for designing dry filter systems and choose the process conditions suitable for laying hen buildings.
In small scale barn measurements the designed dry filter achieved the highest dust reduction efficiency in comparison to the cyclone and wet filter system. Resulting from these experiments the designed dry filter has been recommended for testing in a commercial scale farm. The reduction efficiencies of the designed dry filter under commercial scale barn measurements were 55 and 72 % for indoor concentration and dust emission rate, respectively.
