From ECOTEC we are pleased to share with you our latest case study regarding the successful delivery of a biofilter system with the capacity to treat 100,000 m³/h in a composting plant in Galicia, Spain.

The installation consists of two key towers:

• Humidification Tower: The first stage, where the air is sprayed to increase its humidity. This is essential to ensure that the biofilter media has the necessary humidity.

• Chemical Scrubber: The second tower incorporates a chemical scrubber, where sulfuric acid is introduced to treat the ammonia. This results in the formation of ammonium sulfate as a by-product. This stage is crucial when the air stream contains ammonia, as biofilters cannot remove it directly.

In addition, we supply a complete sulfuric dosing system, including pump and tank. As for the biofilter itself, we provide the necessary filler for its operation.

To ensure optimum performance, we supply two powerful fans of 50,000 m³/h each. These fans work together to overcome the head losses in the entire odor and collector treatment system.

This is a very complete system with the main function of removing the large load of odors, ammonia (NH₃), hydrogen sulfide (H₂S), and VOCs generated in the plant, with the data detailed below:

Below are the performance parameters of the plant:

The implementation of this odor and contaminant removal system proved to be effective, ensuring proper odor management, regulatory compliance and air quality elevation. This instalation reinforces the company's ongoing commitment to sustainability and environmental responsibility.
