Use of TRS Inventories and Air Dispersion Modelling as a Tool for Odour Reduction Strategies: TRS Emissions from a Kraft Mill with an Activated Sludge..., 2001 Environmental Conference Proceedings

B. O’Connor, C. Ledoux--Detailed knowledge of a mill’s atmospheric TRS emissions coupled with air dispersion modelling can be an effective way to plan odour reduction strategies. For the kraft mill in question, the results from the air dispersion model indicated that the emissions from the treatment system were having the greatest, and most frequent, impact on ambient TRS in the surrounding community. Different modelling scenarios demonstrated that a small innocuous vent from the sludge dewatering building (mix tank vent) was a major contributor to ambient TRS in the area surrounding the mill. The model also indicated that eliminating the TRS from this single simple source would significantly reduce the contribution of odours from the treatment system.
