Rotary Drum Screen
Rotating cylindrical screen that provides continuous filtration through slow rotation. Solids collect on the drum surface, are carried out of the fluid as the drum rotates, and are removed by spray wash, scraper, or air blow into a discharge chute. Wedge wire construction maintains consistent slot integrity under operational stress, making it suitable for high-volume wastewater and intake screening.
APPLICATIONS
• Wastewater pre-treatment
• Water intake cleaning
• Food processing filtration
• Mineral processing
