Compared to Collection

Dry Fog has many advantages over dry dust collection systems commonly referred to as Bag-houses. These Dry Fog advantages include:

  1. Dry fog is typically up to 4 times less costly to purchase, operate and maintain. See  pdf Cost comparisons Dry Fog versus collection submitted to the U.S. Environmantl Protection Agency (USEPA) by a PRB Coal Mine.
  2. No duct work is required.
  3. No secondary waste stream to deal with.
  4. Reduced explosion hazard as we do not collect the dust where it is contained waiting for an ignition source.
  5. No moving parts to repair or replace.
  6. Considered BACT for PRB Coal Conveying systems by the Wyoming DEQ.
  7. Now rated as Best Demonstrated Technology or BDT for subbituminous coal handling by the U.S.E.P.A.
