This study was conducted to verify the effect of chlorine dioxide (ClO₂) on odor reduction at a commercial swine facility consisting of a windowless piglet barn and a grower/fattening barn. The windowless piglet barn used a duct ventilation system. Air velocity at very below the upper duct was 4.53 m/s. Air velocity at the lower space around the living space of pigs in the grower/fattening barn was 0.26 m/s. NH₃ concentration was around 9 ppm and less than 3 ppm before and after the ClO₂ spraying, respectively, which was over 70% reduction. There was no H₂S detection. NH₃ concentrations measured in the windowless grower/fattening barn and at the exhausted air were 26 ppm and 11 ppm, respectively. NH₃ concentration at a biocurtain outside was less than 1 ppm. Hence, ClO₂ spraying at windowless barns was effectively decreased malodor such as NH₃.
