NFS - Rotary drum screen - NRF - Technical Data

The outside fed rotary drum screen has a self cleaning wedge wire drum. Particles larger than the slot width are retained on the drum, scraped off and discharged via a shute into a collection skip.

In the inlet compartment an overflow weir is installed to protect the screen from excessive water flows. The capacity of the screen can also be adjusted by the overflow weir.

The rotary drum screen design is including:

  • Wedge wire drum which will retain particles larger than the sloth
  • Continuously renewing filter area
  • Unique spring for uniform pressure on the scraper for cleaning
  • Overflow weir
  • Optional support, depending on location
