Photocatalytic TiO2 coating—to reduce ammonia and greenhouse gases concentration and emission from animal husbandries

Photocatalytic construction and building materials: From fundamentals to applications

“…The photocatalytic removal of NO and NO 2 was 19% and 20%, respectively. Guarino et al [20] chose two identical mechanical ventilated farrowing rooms in a swine farm, where NH 3 was the main pollutant, to study the pollution removal performance of a TiO 2 catalytic paint. Environmental parameters, ventilation rate and gas concentrations were continuously monitored in the catalytic painted room and a reference room.…”

Diurnal Variation of Ammonia Emission in Pig Fattening Facilitties

“…In previous studies has been confirmed that ammonia emissions are highly correlated with feeding and excretory behaviour (Groenestein et al, 2003;de Sousa & Pedersen, 2004;Guarino et al, 2008). Guarino et al (2008) observed that most pigs excreted 1 h or 2 h after feeding and Aarnink et al (1996) found linear relationships between urinating frequency and ammonia emissions. In present study was analyzed also the difference in diurnal variation during fattening period.…”

Degradation of selected indoor air pollutants: Comparison study of photocatalytic, ozone-assisted photocatalytic and amine adsorption processes

“…Today, rather few studies have been carried out on the ozone-assisted photocatalysis of NH 3 . Guarino et al [20] monitored NH 3 gaseous mass concentrations in two identical farrowing units and found the significant decrease of NH 3 mass concentration as a result of TiO 2 mediated photocatalytic oxidation. Dong et al [21] tested the TiO 2 (Degussa P25) which was supported on the woven fabrics for the removal of indoor ammonia and the combination of the fibrous TiO 2 photocatalysts with UV irradiation of 365 nm wavelengths which effectively eliminated gaseous ammonia in the reactor.…”
