Using ozone for odor control in wastewater treatment involves certain challenges, particularly regarding the costs associated with maintaining effective concentrations at large treatment facilities. Ozone is generally a strong oxidant that can effectively neutralize odors. However, producing and maintaining the required concentration of ozone to achieve lasting results can be expensive, especially in large plants where the volume of treated wastewater significantly increases the demand for ozone.

When operating large-scale wastewater treatment plants, the infrastructure needed to generate, distribute, and utilize ozone, combined with the ongoing costs of materials, maintenance, and potential energy consumption, can add up. This economic factor can often make ozone a less viable option when compared to other odor control methods that may be more cost-effective for high volumes of wastewater.

The other concerns related to ozone, such as the need for special handling and potential harmful byproducts, certainly exist but don't directly address the economic aspect that becomes particularly critical in larger facilities. Thus, the cost associated with achieving effective concentrations plays a pivotal role in determining the practicality of using ozone for odor control in extensive wastewater treatment systems.
