There are several industries in which small particles are generated due to high temperature and the raw materials used in the process. These industries are, for instance the glass and glass wool industries, and the metal industries (steel, foundry, welding etc). Fine particles are more demanding for filtering application than coarse dust and requires special measures before the flue gas can be safely recycled or released to the environment.

For these purposes, Tassu offers a NASU H-EDF technology that is substantially more efficient in fine particle removal than conventional ESPs. NASU H-EDF demands less maintenance than bag filters and has better overall cost efficiency.
