Rotary Screen

Product Details

The Rotary Screen (External Fed Rotary Drum Screen) is a rotating drum screen for continuous and automatic separation of fine solids from wastewater. It uses a stainless steel wedge wire screen with openings of 0.25–3.0 mm, supports wastewater with high oil or grease content, and comes with a scraper blade and water spray system to help reduce clogging.

Key Features: Rotary Screen
  • Rotating drum separates solids continuously and automatically
  • Wedge wire or perforated SUS304 screen with openings of 0.25–3.0 mm
  • Equipped with a scraper blade and water spray system to help clean the screen
  • Handles wastewater with high oil and grease content well
  • Stainless steel structure, strong and corrosion resistant
  • Requires little space and helps reduce labour in solids separation
Benefits: Rotary Screen
  • Separates finer solids than a Static Screen, reducing TSS and particulate BOD
  • Operates continuously with no cleaning stoppages
  • Reduces clogging of downstream pumps and air diffusers
  • Increases the system's wastewater throughput capacity
Working Principle: Rotary Screen
  • 1. Wastewater is fed and distributed over the outer surface of the slowly rotating drum screen.
  • 2. Liquid passes through the mesh into the drum interior and is discharged.
  • 3. Solids are captured on the outer surface and removed by the scraper blade and water spray into a collection trough.
  • 4. The cycle runs continuously and automatically to prevent clogging.
