Basic drum 25 (gravity)
Drum filters serve as the first step in the filtration process. Using a drum that is fitted with stainless steel mesh, they filter coarse waste out of the water and automatically flush the waste into the sewage system. The openings in the mesh are only 70 microns wide, which means that practically all waste is removed from the water, so that the biological filter behind the drum can function optimally.
