odormanagement

Odor management, sometimes written as odor-management, refers to the systematic planning, execution, and oversight of measures designed to prevent, control, and mitigate nuisance odors generated by human activities. It is applied across sectors such as wastewater treatment plants, landfills, composting facilities, rendering plants, and various agricultural operations, with the aim of protecting air quality, complying with regulations, and reducing community impact.

Assessment and measurement are key components. Odor is typically quantified using odor concentration units and hedonic assessment, often through dynamic olfactometry according to international standards. In addition to sensory methods, monitoring may include analysis of volatile organic compounds and reduced sulfur compounds. Odor dispersion is commonly modeled to understand how emissions affect nearby communities under varying meteorological conditions.

Control strategies fall into several categories. Source control focuses on process changes to minimize odor generation. Containment involves sealed or enclosed equipment and covered processes to prevent emissions. Abatement technologies reduce or destroy odorants, including biofilters and biotrickling filters that use microorganisms, activated carbon adsorption, wet or dry scrubbers, and thermal or catalytic oxidizers. Operational measures such as scheduling maintenance, improving housekeeping, and optimizing by-product handling complement technology. Effective odor management often combines multiple approaches tailored to site-specific odorants, flow rates, and energy considerations.

Regulatory and community aspects include odor impact assessments, permit requirements, odor control plans, and stakeholder engagement. Odor management programs benefit from ongoing maintenance and performance verification, staff training, and periodic re-evaluation as operations or regulations change. In practice, successful programs balance technical feasibility, cost, and social acceptance while adapting to climatic and seasonal variability.
