RBS Rotary Screen also called as rainwater screen cleaner, is widely used to block and get rid of floating debris in rainwater pump ，Station, wastewater pump station, water supply pump station and influent pump station of sewage treatment plant municipal wastewater treatment.
2 Structure & Working Principle.
Residue sizes larger than bar spacing get blocked by the screening surface while sewage flowing by, the tines of rake tooth plate go deep into the screen space. Residue blocking the screen surface will be raked up to the top by rake tines, under driven of driving chain and get discharged by gravity as they reach the top of the discharge outlet. Residues dropped from discharge outlet will fall into the conveyor or trash car for further processing.
