DEC.AFU™
activated carbon filters
DEC IMPIANTI • your environmental partner
DEC IMPIANTI offers our customers a highly efficient treatment system to remove and recover or oxidize VOCs (Volatile Organic Compounds) from gaseous process streams.
A global leading supplier of equipment and services for environmental compliance and sustainability.
As worldwide market leaders in activated carbon solvent recovery units (SRU), inert gas (nitrogen, N2) regenerated, DEC IMPIANTI has designed, engineered and delivered more units than any other competitor combined.
DEC.AFU™ • activated carbon filters
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 filters are a cost-effective and efficient way to remove VOCs from the air. Activated carbon is a porous material that has a large surface area: this allows it to trap VOC molecules, which are then unable to escape back into the air.
Disposable activated carbon filters are available in a variety of sizes and shapes, suiting several needs for different industrial applications.
To ensure that DEC.AFU™ disposable activated carbon filters are effective, they should be replaced on a regular basis: the frequency of replacement will depend on the level of VOC emissions in the air.
DEC.AFU™ disposable activated carbon filters are a safe and effective way to remove VOCs from the air: they can help to improve air quality and protect human health.
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 performance.
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 has to be replaced, the carbon, has to go through the reactivation phase, a high-temperature process which destroys trapped organic pollutants and frees up the pores of the adsorbent. All activated carbon in the form of pellets (granule or extrudate) which are hard enough can be reactivated and thereby have most of their initial capacity restored: services provided by DEC SERVICE.
When the quantity of the carbon is very low, the adsorbent may be disposed-off.
