Wet washing towers or wet scrubbers transform pollutants in the air from the gaseous state to the liquid state through countercurrent washing of the air stream. Inside them, pollutants are stabilized and rendered odorless. This is achieved through the absorption principle employed by wet washing towers, where specific packing materials or exchange packs are placed inside a washing chamber. The chamber is constantly irrigated with a pressurized aqueous solution.
To ensure the effective treatment of polluting substances, the aqueous solution must have the appropriate pH and redox potential. Acidic pollutants are treated with alkaline solutions, while alkaline ones are treated with acidic solutions.
Storage tanks containing these aqueous solutions are equipped with complete dosing systems, including dosing pumps, allowing for the precise dosing of the necessary reagent to ensure effective odor removal.
After completing the washing process inside the tower, the airflow goes through a droplet separator, which recovers and prevents residual droplets from being released into the environment.
Scrubbers used for air treatment can be configured with one, two, or more stages, depending on the types of pollutants present and their concentration.
Wet scrubbers are widely used for odor treatment in various sectors, including:

We have introduced a series of features to our Scrubber system aimed at optimizing pollutant treatment, including:
These features make our system even more efficient and adaptable to specific needs
When superior efficiency in odor abatement is required, it is possible to build into a wet scrubber a series of other air/odor treatment systems, in order to create a multi-stage system.
The choice between a single-stage or multi-stage approach depends on the nature of the emission problem, constraints, and design objectives. Our ability to develop a concrete proposal, to be implemented by our technicians, is based on an accurate analysis of this information.
By introducing an additional treatment step with the help of an osmogenic barrier in traditionally designed wet abatement systems, it is possible to achieve a level of effectiveness in odor abatement that would be very difficult to obtain using a single step system.
It is possible to use some additives to increase wet scrubbers efficiency performances.
