GORE® Membrane Technology vs. Non-Membrane Media: Industrial Baghouse Filters

Baghouse Filtration using Membrane Technology vs Non-Membrane Media

English,

Learn the differences between membrane and non-membrane filter media. GORE Membrane Technology provides longer bag life, lower emissions rates, lower pressure drops and better has throughput.


non-membrane

Non-Membrane Depth Filtration

Filtering Mode

  1. Dust is filtered inside of filter media
  2. Internal dust cake buildup required
  3. Particles enter into filter media and can pass through
  4. Might not filter finest particles
  5. Efficiency requires careful balance between filter, particulate, and system conditions

Cleaning Mode

  1. Difficult to remove particles, only surface dust cake is removed
  2. Dust deep inside media can cause higher Dp and blinding with time
  3. Dust buildup inside media can lead to emissions after cleaning

membrane

Membrane Surface Filtration

Filtering Mode

  1. Dust filtered at membrane surface
  2. No dust cake buildup required
  3. No particles enter backer
  4. Capable of submicron filtration
  5. Maintains capture efficiency over wide range of system conditions

Cleaning Mode

  1. Almost all dust falls off membrane surface
  2. Particles do not build up inside backer
  3. Surface is hydrophobic, even wet dust cakes can still be handled

GORE™ Membrane Efficiency and Versatility

Membrane (500x)

membrane

Surface Filtration
Uniform membrane structure allows higher efficiency.

Non-Membrane (500x)

Non-Membrane (500x)

Depth Filtration
Dust still penetrates into backer and is trapped.
