Odor and corrosion problems from various manufacturing processes are often the result of multiple airborne contaminants. Industries such as pulp and paper, oil and gas refineries and wastewater treatment generate contaminants such as hydrogen sulphide, an undesirable by-product which is malodorous, toxic and highly volatile.

In wastewater treatment facilities, specific characteristics such as basin detention times, loadings to biological processes and sludge generation potential can influence the odor levels.

Septage and sludge handling systems are also common sources of strong odors. Odor generation is often the result of organic overloading, inadequate supply of air, improper ventilation, or simply the failure to recognize that certain unit processes may require the implementation of special odor control technology.

Typical nuisance odors and corrosive contaminants are also produced in the manufacturing of chemicals, fertilizer, pharmaceuticals and food processing, as well as waste transfer stations, incineration plants and garbage depots.

The ability to control odorous emissions has become a growing concern as cities and populations are expanding closer to plant facilities. The objective of odor control is to prevent or minimize nuisance odor levels to the surrounding community. Safety and comfort of the employees working in plant facilities has also become a top priority. National and local regulations on air quality are more severe, responding to neighbour complaints and environmental groups.
