Citizen complaints about odor need to be taken seriously to avoid negative publicity, regulatory orders and perhaps civil actions.
LEHDER has a unique phased approach to odor investigations to ensure the problem is clearly understood; solutions are developed to address the root cause of the odorous emissions. Specific situations require specific solutions.
Phase 1 - Assessment of Odor Issues
LEHDER personnel perform a qualitative evaluation at the facility over a period of several days. The objective is to become familiar with the odor issue, evaluate potential factors contributing to off-site odors, and to identify a list of significant odor sources for subsequent sampling and modeling.
Phase 2 - Quantification of Odor Sources
During Phase 2, the sources identified in Phase 1 will be sampled and analyzed to determine the odor emission rate. If appropriate, the emission rate of specific contaminants present in the discharge is determined. Although the resolution of odor issues is seldom resolved through measurement of emissions of specific compounds, it provides credibility to a facility to be able to indicate knowledge of the emitted compounds. LEHDER follows the testing methodology outlined in the MOECC Ontario Source Testing Code.
Phase 3 - Odor Impact Analysis
The primary objectives of Phase 3 are to:
- evaluate the extent to which odorous emissions impinge on neighbouring buildings located around the facility
- identify specific sources which contribute significantly to ground level odor concentrations
- provide recommendations for designing stack heights and velocities in order to provide maximum dispersion
Phase 4 - Solution Development
The objective of Phase 4 is to identify practical, effective solutions. The information gathered during the first three phases is used, in conjunction with a control technology review, to develop odor abatement solutions.
LEHDER has developed effective solutions for many different industries, including organic chemical manufacturers, glass fiber plants, rendering plants, and food processors.
