Optimisation of ventilation systems and regimes as a strategy for ammonia and odour emission reduction in mechanically ventilated fattening pig buildings



The PhD study is part of a larger project on entitled "Techniques and management tools for odour and dust emission reduction in Flemish piggeries" which consist of five different work packages (WP). The focus of this PhD study is on the ventilation aspect of the project. The PhD study aims at developing an experimental test platform in the first 2 years of the PhD study Foto 1 Tabaseso that optimal ventilation strategies/regimes that can reduce ammonia and odour emissions from fattening pig buildings can be tested in combination with other emission reduction strategies (e.g. c leaning, spraying and manure management techniques). The experimental test platform will be developed at a newly constructed fattening pig building at the Flemish Institute of Agriculture and Fisheries (ILVO), Merelbeke. A Computational Fluid Dynamics (CFD) model will be developed as a supplementary tool to help identify some of the optimal ventilation strategies to be tested at the test platform.

In addition to the CFD model tool,Foto 2 Tabase a simple dynamic indoor climate and NH3 emission mathematical model will also be developed so that the effects of different ventilation regimes on indoor climate and NH3 emissions can be quickly tested in order to reduce costs involved in experimental studies at the test platform. Finally, a full scale experimental investigation with real pigs will be conducted in year 3 and 4 at the ILVO fattening pig facility where identified optimal (low NH3 and odour emission) ventilation regimes/strategies from the first 2 years of the study will be tested, combined with other low emission reduction strategies so that new emission factors and pig performance information can be developed
