Adsorbent Filtering Unit
DEC.AFU™

Volatile organic compounds (VOCs) are a major source of air pollution: they can cause a variety of health problems, while contributing to climate change.

DEC.AFU™ disposable activated carbon industrial filters are a cost-effective and efficient way to remove VOCs from the air. Adsorbents (e.g. activated carbon) are porous material that show a large surface area: this allows it to trap VOC/HAP molecules, which are then unable to escape back into the air.

Disposable adsorbent filters are available in a variety of sizes and shapes, suiting several needs for different industrial applications.

To ensure the effective performance of DEC.AFU™ disposable adsorbent filters, a preliminary compatibility assessment is required to verify their ability to safely and efficiently adsorb the specific VOCs or HAPs present. Routine filter replacement is essential, with the frequency determined by the maximum allowable concentration of these substances at the stack.

DEC.AFU™ filters are a safe and effective way to remove VOCs from the air: they can help to improve air quality and protect human health. Non-regenerable disposable adsorbent filters are a cost-effective solution for controlling VOC/HAP emissions typically lower than 10 tons per year.

DEC.AFU™ • primary stage filtration

DEC.AFU™ primary stage filtration, also known as sacrificial filtering units (usually in coalescing configuration C-AFU™), to combine combines the functions of a coalescing filter and an activated carbon filter) are typically installed prior to a DEC.SRU™ solvent recovery unit to protect it from unwanted contaminants (HHB): the C-AFU™ traps and absorbs the contaminants, reducing the contaminat quantities reaching the DEC.SRU™ solvent recovery unit. This will help to extend the life of the adsorbent used in the DEC.SRU™ while improving its performances.

DEC.AFU™ • secondary stage filtration

The DEC.AFU™ unit can be coupled with the DEC.RSC™ direct condensation for further reduction of VOC emissions at the stack of the DEC.SRU™ solvent recovery unit.

DEC.AFU™ • backup filtration

DEC.AFU™ can be used as an emergency backup system to the main VOC abatement plant (typically an oxidizer) is required, the solution to install a temporary and/or disposable activated carbon filter (DEC.ACF™) may be the winning selection.

DEC.AFU™ • replacement and disposal

Once the activated carbon filter is saturated with the contaminant, the active carbon is then replaced with new carbon. The carbon is usaully going through an off-site reactivation process, a high-temperature cycle which destroys trapped organic pollutants and frees up the pores of the adsorbent, thereby having most of its initial adsorption capacity restored: services provided by DEC SERVICE.

When a low quantity of activated carbon is employed in the DEC.AFU™, the adsorbent may be disposed-off, according to applicable regulations.
