Rotary Drum Fine Screen: Essential Equipment for Wastewater Treatment Pretreatment

April 26, 2026

Comments are closed.

Rotary drum fine screens are critical pretreatment equipment for removing fine solids from wastewater, protecting downstream processes and equipment from damage and clogging.

How Rotary Drum Screens Work

Wastewater flows into a rotating drum covered with a perforated screen. Solids larger than the screen openings are retained on the surface while filtered water passes through. Brushes or spray nozzles continuously clean the screen, with collected debris transported to a collection trough for disposal.

Screen Specifications and Selection

Screen Aperture

Common opening sizes range from 0.25mm to 6mm, with finer screens providing better protection but requiring more frequent cleaning.

Flow Capacity

Single units handle flows from 50 m³/h to over 2,000 m³/h, with multiple units installed in parallel for larger applications.

Material Options

  • SUS304 stainless steel for standard applications
  • SUS316L for corrosive or high-temperature applications
  • Special alloys for aggressive chemical environments

Applications

  • Municipal wastewater treatment plant inlet
  • Industrial pretreatment before biological treatment
  • Food and beverage processing wastewater
  • Paper and pulp industry
  • Chemical and pharmaceutical facilities
