Odor control can be broken down into two main categories: 1) Eliminating odor in the air 2) Changing the chemistry of the water to keep the water from going septic. There advantages and disadvantages to both types of odor control. For example, simply treating the air in the system may be more economical for the lift station customer but many treatment plants wont except the septic water without treatment. The treatment plant may not have the capability to treat the influent waste water, especially if many lift stations of this nature are coming to the treatment plant, or they may not want to have the responsibility of treating the water when it is sourced from another owner (i.e. the lift station owner). There are obvious cost to the treatment and the treatment plant may not want the responsibility. Another factor could be the intensity of the smell. The system may have a low odor that doesn’t need chemical treatment and air treatment would be the best option. However, the smell intensity of the waste water may be due to high concentrations and changing the chemistry of the water may be the best/only option for treatment. There are many other factor for choosing one category over the other. Things like distribution of odor control systems in the area, industrial facility requirements, the surrounding environment, community involvement, ect all contribute to the determination of the odor control system.
