Perfect for Membrane Bioreactors (MBR) and the headworks of WWTP. The OR-TEC Rotary Brush screen is manufactured from stainless steel and is designed to remove fibers, hair and other foreign objects from a waste stream. It uses a static stainless steel perforated semi cylindrical screen bed for this purpose. This bed is continually cleaned by a stainless steel armature with brushes. The brushes are selected based on the particular waste and gently sweep the screen bed. This action cleans the screen bed but puts no pressure on the screen bed. OR-TEC Rotary Brush Screens are designed, engineered and manufactured in the USA.
