With the release, in 2011, of new, more restrictive dry particulate emission regulations by the EPA, such as Boiler MACT, CSAPR, and other, tighter EPA emissions mandates, it is incumbent on dry filtration media technology to keep pace with these new lower restricted dry particulate emission requirements.
A high-tech PTFE membrane supplier, TTG, Inc., has developed a state-of-the-art advanced filtration-efficiency, expanded PTFE filtration membrane. Utilizing brand new, state-of-the-art ePTFE laminating equipment, this ePTFE membrane can be laminated to a wide range of filtration substrates, such as Polyester, Acrylic, PPS (Ryton), Nomex, and Fiberglass. A unique property of the ePTFE media is an enhanced ability to release the dust cake during baghouse pulse cleaning, which enables the filter bags constructed with the ePTFE membrane to run at a 2.0” to 2.5” w.c. lower differential pressure drop (DP) when compared to other traditional PTFE membrane constructed filter bags. Test results indicate the TTG ePTFE membrane is the highest quality, in the world, for 0.000001 grs/dscf filtration.
 
Recently, a leading OEM supplier of large gas volume baghouse systems stated, “It is not a difficult choice to make in selecting the TTG membrane filter bag as our filter media when I can be assured of achieving the new EPA-mandated 0.008 lbs/MMBtu dry particulate emission standard. As a bonus, our baghouse systems perform at a 2” to 3” w.c. lower differential pressure across the filter bags by simply replacing the current PTFE membrane bags with the new ePTFE membrane constructed filter bags.”
