Integrated Internally Fed Rotary Drum Screen Filter
Short Description
The Hydronovus Internally Fed Rotary Drum Screen is a highly reliable, compact solid-liquid separation device engineered for continuous industrial and municipal wastewater pretreatment. Designed to efficiently capture solid particles larger than 0.2 mm, wastewater enters the drum through a feed inlet, flows over a distribution weir, and passes onto the inner surface of the rotating drum. Solids are retained on the screen and continuously discharged, while the purified liquid passes seamlessly through the mesh, ensuring optimal protection for downstream biological processes.
🌟 Key Engineering Advantages
- Clog-Free V-Wire Technology: The screen mesh features an inverted trapezoidal (V-wire) cross-section. This intelligent design effectively prevents solid waste and fibrous materials from wedging into the gaps, eliminating the risk of blinding.
- Advanced Self-Cleaning System: Equipped with an internal dual-brush mechanism and a high-pressure spray system. This ensures the screen surface is thoroughly and continuously cleaned during operation, maintaining stable, long-term filtration performance.
- Zero Civil Works Required: Unlike traditional in-channel screens, this fully enclosed unit features a compact footprint and requires no concrete channel construction. It can be bolted directly to the floor using expansion bolts, with simple flanged connections for the inlet and outlet.
- Optimized Variable Operation: Powered by an adjustable-speed motor, allowing plant operators to fine-tune the drum's rotation speed to adapt to varying hydraulic flow conditions and solid loading rates.
- Heavy-Duty Construction: Manufactured from high-strength, corrosion-resistant Stainless Steel 304 (SS316 available upon request), guaranteeing a long service life even in harsh, highly corrosive environments.
