Rotary Drum Screen
Rotating cylindrical screen that provides continuous filtration through slow rotation. Solids are separated without interrupting process flow. 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
