Perstrup pig house with partial under-floor air evacuation and in-house separation of faeces and urine

This paper deals with a newly developed Perstrup pig house with partial under-floor air evacuation and in-house separation of faeces and urine.

Abstract

The under-floor air evacuation was very efficient in reducing ammonia concentration in the room and improved the air quality and the working environment significantly. The ammonia concentrations in the room were very low compared with the exhaust air beneath the slats due to a very efficient under-floor evacuation. On average, the ammonia concentration was below 0.5 ppm in the room and more than 10 times as low as the under-floor outlets. The odour concentration was also higher in the exhaust air beneath the slats compared with the concentration in the room, but only with a ratio of 1.6 in the control room and 1.8 the room with in-house separation.

Odour emissions were 16% higher in the room with in-house separation due to higher odour concentrations in the outlets from the under-floor air evacuation.

The in-house separation has shown high separation efficiencies, but the in-house separation still needs to be improved to increase the dry matter content and reduce the amount in the solid fraction.
