The Seft GRR is a rotary drum filter constructed in a stainless-steel case with wedge-wire for waste water treatment. The waste water flows in the feeding tank through a flanged-spout and is transported to the outer surface of this equipment.
In addition, the clean and processed water is transported through a filter surface toward the outlet spout, while the solid particles stay on the rotary drum surface as these particles are to be removed by the fix blame.
