Gas Concentration Measurements from Pig Barns and Potential Impact of Air Quality on Pig and Human Workers

Focus on mitigation requirements in Northern Europe is driving examination of, and in some cases adoption of new or rediscovered technologies. The three which seem to me to hold most promise are Electronic Particle Ionisation employed within the building (relatively low cost) and good for particulate reduction, Slurry acidification (expensive installation) but fixes ammonia during storage and spreading to land and gives higher quality slurry for a return on investment and Slurry cooling using heat pumps with both cooling and heating available from the process. In order to evaluate these technologies we have to measure the problem so this is a useful and interesting presentation.
