Biofiltration of n-butyric acid for the control of odour

Sheridan, B. A. ; Curran, Thomas P. ; Dodd, V. A. (Elsevier, 2003-09)

Odour control from pig production facilities is a significant concern due to increased public awareness and the development of more stringent legislation to control production. Although many technologies exist, biofiltration ...
The influence of diet crude protein level on odour and ammonia emissions from finishing pig houses

Hayes, E. T. ; Leek, A. B. G. ; Curran, Thomas P. ; Dodd, V. A. ; Carton, O. T. ; Beattie, V. E. ; O'Doherty, J. V. (Elsevier, 2004-02)

Feed trials were carried out to assess the influence of crude protein content in finishing pig diets on odour and ammonia emissions. Eight pigs (4 boars and 4 gilts), average initial weight 70.8 kg (s.e. 3.167) were housed ...
SE—Structures and Environment: Biofiltration of Odour and Ammonia from a Pig Unit—Biofiltration of Odour and Ammonia from a Pig Unit—a pilot-scale Study

Sheridan, B. A. ; Curran, Thomas P. ; Dodd, V. A. ; Colligan, J. (Elsevier, 2000-08)

A pilot-scale biofiltration unit was constructed at a pig finishing building on the University College Dublin research farm. The biofiltration system was investigated over three trial periods. Exhaust air from a single pen ...
A dispersion modelling approach to determine the odour impact of intensive poultry production units in Ireland

Hayes, E. T. ; Curran, Thomas P. ; Dodd, V. A. (Elsevier, 2006-10)

The use of atmospheric dispersion modelling has become more common for the determination of odour impacts from existing poultry production facilities and the assessment of setback distances for new facilities. Setback ...
Odour and ammonia emissions from intensive pig units in Ireland

Hayes, E. T. ; Curran, Thomas P. ; Dodd, V. A. (Elsevier, 2006-05)

Odour and ammonia emissions were measured at four intensive pig units in Ireland. Odour samples were collected on-site and analysed for odour concentration using an olfactometer. Ammonia concentrations in the exhaust ...
