Issues related to WWTP sludge odors

The storage and handling of wastewater treatment plant (WWTP) sludge generates strong, persistent odors that can cause significant odor nuisance for neighboring areas. Controlling these odor emissions is a major challenge in neutralizing sludge odors, reducing the site’s odor impact, and complying with environmental requirements.

Odor treatment solution implemented

Odor treatment is provided by dry steam air treatment technology, which is particularly well suited to wastewater treatment and sewage sludge storage sites. The solution is based on the controlled diffusion of an odor neutralizer made from pure essential oils, without water.

Technical description of the installation:

The installation includes:

• 100 linear meters of dry steam ramp installed along the walls of the storage area
• 1 VS200 P cabinet (1 nozzle equipped with an LPA turbine, an air pump, and a weather station)
• Homogeneous diffusion of the odor neutralizer throughout the platform

Intelligent control system:

A weather station allows the odor treatment to be adapted according to prevailing winds, disruptive winds directed towards local residents, and windless conditions.

Advantages of the solution:

• Targeted neutralization of WWTP sludge odors
• Significant reduction in odor nuisance
• Waterless treatment, no risk of freezing
• Eco-friendly and effective solution all year round
