TiO2 Photocatalytic Oxidation Technology

Animal production is a main source of NH3 emission into the environment and a significant producer of other polluting gases.

Most of the old available style products and the widely used techniques that are used today are mostly not effective enough - and costly when applied in the field - especially in existing live stock buildings.

Industrial applications show that Solas Shield TiO2 Photocatalytic Oxidation (PCO)treatment can be used to transform NH3 into N2, N2O or NO and water at a fraction of the cost.

Field experiments to assess the potential efficiency of Solas Shield TiO2 PCO have already determined the vast improvements to indoor air quality and NH3 and polluting gas emissions into the environment by coating pig house walls with TiO2 PCO and this easily applied technique is now available as a low cost and proven efficacy for animal farmers.

Previous trials were conducted in two identical mechanical ventilated farrowing rooms. Environmental parameters, ventilation rate and gas concentrations were continuously monitored in the two units throughout a 28 day production cycle.

NH3, N2O, CO2, CH4  average concentrations of 5.41, 1.18, 6.28 and 2109.38 mg m(-3) (reference unit) whereas  3.76, 1.13, 5.32 and 1881.64 mg m(-3) (treated unit) were recorded during a full farrowing cycle.

Pollutant emissions, expressed on a Livestock Unit (LU, i.e., 500 kg live weight) basis, were 16.33, 3.57, 18.96 and 6365.01 kg y(-1)LU(-1) (reference unit) and 11.37, 3.43, 16.11 and 5695.58 kg y(-1) LU(-1) (treated  unit).

Significantly higher pollutant concentrations and emissions were also found in the untreated reference unit, under similar environmental conditions and also with identical numbers of sows and piglets per unit.
