stp pretreatment system

The Rotary Drum Screen Filter is an internal feed fine screening system designed for wastewater pretreatment and solid-liquid separation. It removes suspended solids larger than 0.2 mm using a continuously rotating cylindrical screen. Wastewater flows into the drum interior and is evenly distributed across the screen surface for efficient filtration. It is widely used in municipal sewage, industrial wastewater, cooling water, irrigation, and RO pretreatment systems to improve downstream treatment performance and reduce maintenance load.
