Effects of TiO₂ based photocatalytic paint on concentrations and emissions of pollutants and on animal performance in a swine weaning unit

The beneficial effect of a TiO₂-based photocatalytic treatment on the indoor air purification of a swine farm has been evaluated in a trial performed in two identical mechanically ventilated traditional weaning units, with 391 animals lodged in each of them. One unit was used as reference, whereas t...

Description
Summary:The beneficial effect of a TiO₂-based photocatalytic treatment on the indoor air purification of a swine farm has been evaluated in a trial performed in two identical mechanically ventilated traditional weaning units, with 391 animals lodged in each of them. One unit was used as reference, whereas the walls of the second unit (260 m²) were coated with ca. 70 g m⁻² of TiO₂ and irradiated with ten UV-A lamps. The environmental parameters (i.e. the ventilation rate, the internal and external temperature and relative humidity), together with NH₃, CH₄, CO₂ and N₂O concentrations in the exhaust ducts and PM₁₀ emissions, were monitored in the two units throughout all of the production cycle (75 days). Significant decreases in CH₄ concentration (ca. 27%, P
