Rotating Drum Screen Provides High Solid Liquid Separation

Description

What Is External Rotary Drum Screen

Self-cleaning wedge wire screen. Primary screening separator and removes non dissolved solid materials that could cause mechanical damage and blockages to the next treatment steps in WWTP.it is a proven fine screening technology for municipal wastewater treatment plants and many industries with several application capabilities.

How Does External Rotary Drum Screen Work?

The discharge to be treated enters through the shaped wall located outside the screen body,
Evenly distributed by the overflow channel, and overflows on the rotary drum filter. Solids will remain on the rotary drum surface as the drum rotates, and the effluent entering through the screen will perform self cleaning function when it passes through the bottom of the rotary drum again. After passing through the external scraper, the solid is detached from the rotary drum.
