Yes. Exeon’s hi-flo™ activated carbon system is specifically designed for industrial applications where large volumes of contaminated air need to be treated reliably before atmospheric discharge.
High airflow requirements are common in waste transfer stations, RDF plants, wastewater facilities, anaerobic digestion sites and large industrial buildings. In these environments, significant quantities of air may need to be extracted to capture odours effectively and maintain suitable conditions within enclosed process areas.
The modular design of hi-flo™ allows the activated carbon treatment capacity to be configured around the airflow requirements of an individual site. Exeon states that hi-flo™ systems can treat airflows from approximately 5,000m³/hr to 100,000m³/hr and above, with individual modules capable of handling up to approximately 80,000m³/hr. Multiple units can be installed where substantially larger air volumes need treatment.
How Does hi-flo™ Handle High Airflows?
Treating a large volume of contaminated air involves more than simply installing a larger fan.
The activated carbon needs sufficient contact time with the contaminated air for pollutants to be effectively adsorbed. Air must also be distributed evenly throughout the carbon bed to prevent untreated air from finding lower-resistance routes through the media.
The deep-bed configuration of hi-flo™ provides a substantial quantity of activated carbon and creates controlled resistance through the filter bed. This helps maintain effective air distribution and provides the contact required for treatment of contaminants such as hydrogen sulphide, ammonia, mercaptans and VOCs.
Where high levels of particulate matter are present, dust pre-filtration can also be incorporated to protect the carbon and maintain airflow through the system.
Where Are High-Airflow Carbon Systems Used?
High airflow treatment is particularly important within waste-handling facilities.
Large tipping halls, waste reception areas and RDF processing buildings can require significant extraction rates to capture contaminated air before odours escape from the building. Exeon’s hi-flo™ waste handling emission treatment systems are designed for these environments, including high-capacity VOC and odour treatment under changing process loads.
Large-scale activated carbon treatment can also be applied to sewage works, composting facilities, anaerobic digestion plants and industrial manufacturing sites.
Exeon provides a wider range of industrial odour and emission control systems where particularly complex or high-volume applications require alternative or additional treatment technologies.
Can Multiple hi-flo™ Units Be Used Together?
Yes. One of the advantages of hi-flo™ is its modular design.
Multiple modules can be operated in parallel where the required airflow exceeds the capacity of an individual unit. This enables the treatment system to be scaled for larger facilities rather than requiring a completely different filtration technology.
The containerised units can also be arranged around available plant space, including configurations designed to minimise the installation footprint.
Correct system sizing should consider:
- Normal and maximum airflow
- Contaminant concentrations
- Required carbon contact time
- Pressure losses through ductwork and filtration
- Dust loading
- Available installation space
- Fan duty
- Future changes in process capacity
For particularly complex applications, hi-flo™ may also be integrated with other industrial air filtration technologies, including airo-flo™ biological filtration or scrubX™ wet scrubbing.
By assessing airflow alongside contaminant loading and treatment requirements, Exeon can configure hi-flo™ for both individual process extracts and demanding high-volume industrial ventilation systems.
