Optimisation of a non-thermal plasma scrubber for reduction of odour emissions

Intensive pig production is a major cause of odour nuisance in the local environment and is also associated with a high load of nitrogen to the atmosphere. This project aims to develop and optimize an air cleaner based on application of high voltage to a contaminated air stream.

The environmental impact of pig production is acute in areas with a high livestock production, but is expected to spread as a consequence of an increasing global food demand.

In order to counter this trend, there is a general interest in development of abatement technologies. Such technologies should be efficient as well as economically realistic for the farmers.

This project aims to develop and optimise an air cleaner based on application of high voltage to a contaminated air stream.

As a first step, a dedicated PhD-study will be carried out in order to characterise the air cleaner with respect to removal of odour compounds present in ventilation air from pig houses. The PhD-project involves application of advanced chemical methods for analysis of the effect of the air cleaner on odour compounds.

Based on the project, it is expected that a new type of efficient air cleaner with low operational cost will be made available. The results will also be very relevant for application of air cleaners in various industries.
