A.B.P. Chemical Engineering and Ventilation Ltd. provided full engineering design and supply of an odor and air extraction system to prevent fugitive odor emissions to the surrounding environment.
The project was carried out for one of Israel’s largest municipal waste transfer stations and included the installation of a 350,000 m³/h air extraction and treatment system, incorporating six dust filters and six activated carbon filters for odor and VOC removal.
At the waste collection and sorting facility, household waste was concentrated in a large, open pit exposed to the surrounding environment.
As part of the site’s odor control improvements, the client constructed a closed building to contain all waste-handling operations.
This enclosure enabled the design of an air extraction system for odor removal and to maintain negative pressure within the building, preventing fugitive odor emissions to the environment.
After the installation of the new ventilation system by A.B.P. Chemical Engineering and Ventilation Ltd., air quality at the station improved significantly, and complaints from nearby residents stopped completely. We are very satisfied with the professional and effective solution provided by the company.
A.B.P. Chemical Engineering and Ventilation Ltd. designed a complete extraction system that included sealing the hangar and establishing a comprehensive air collection and treatment network.
The extracted air passes first through self-cleaning dust filters and then through activated carbon filters for odor removal.
The network was divided into six extraction lines, each handling approximately 60,000 m³/h, totaling around 360,000 m³/h.
Extraction flow rates were defined based on several engineering considerations:
Each extraction line included a self-cleaning dust filter followed by an activated carbon filter, with paired lines connected to shared stacks.
To further improve efficiency, air curtains were installed above building openings, separating odor-laden air inside from clean air outside.
Continuous emission monitoring devices were installed on the stacks for TOC, CO, and airflow measurement to ensure proper system operation and regulatory compliance.
Following the installation of the new ventilation system, odor emissions were reduced dramatically, and the facility achieved odor concentration levels among the most stringent worldwide.
