CST - Model EM100-G - Ultra Screen 100 - 400 Microns - Datasheet

The fine screening is normally obtained by means of screens consisting of metal nets or drilled sheet with openings even smaller than 1 mm. These screens retain all the materials which is larger than the opening size, but in some cases, if the material in the sewage arrives with larger side parallel to the screen openings, it cannot be retained. In other cases it happens that there is a quick clogging because of the grease present in the sewage with the consequent need of long and expensive maintenance works for cleaning. Moreover if the sewage contains solid threadlike material, it can clog the openings and give problems to the scrapers operation.
