High-Performance Advanced Solid-Liquid Separation Without Clogging
Maximize your process efficiency with the compact and highly efficient Rotating Drum Screens. Engineered to handle heavy-duty industrial and municipal waste streams, this system effortlessly separates solids and recovers valuable materials without blinding or clogging.
Whether you are managing oily, greasy, fibrous, or resinous matter, drum screen ensures continuous operation and drier recovered solids, handling high flow rates from 200 to 4,650 gal/min (760 to 17,600 liter/min).
Key Features & Technical Capabilities
- Advanced Non-Clogging Technology: Features a cutting-edge self-cleaning arrangement combined with a full-length water knife that continuously dislodges trapped particles, ensuring uninterrupted flow.
- Precision Filtration: The durable cylinder is constructed with high-grade wedgewire screening, available in a wide range of orifice sizes from .002 to .110 in. (50 micron to 2.79 mm) to match your specific particle size requirements.
- Superior Moisture Reduction: Equipped with a variable-speed drive that allows operators to adjust the drum’s rotation speed. This optimizes dwell time and maximizes dewatering effectiveness, reducing moisture levels down to the 20% range for drier, lighter, and easier-to-manage solids.
- Smart, Compact Footprint: Consisting of a horizontal cylinder, variable speed drive, head box, baffle flow plate director, and discharge chute, the entire integrated system requires significantly less floor space and headroom than conventional, non-rotating separation equipment.
Comprehensive Features
- Minimal Moving Parts, Maximum Uptime: With the rotating drum being the only moving part, mechanical wear and tear are virtually eliminated. This ensures an exceptionally long service life and prevents unexpected operational downtime.
- Consistent Efficiency: Continuous self-cleaning mechanism prevents downtime caused by screen blinding, keeping your production line moving smoothly.
- Eco-Friendly & Value-Driven: Efficiently recovers valuable solid products from process streams while significantly reducing waste disposal costs.
- Space & Installation Efficiency: The compact, low-profile design allows for easy integration into existing facilities where space and headroom are strictly limited, eliminating the need for expensive structural modifications.
- Unbeatable Cost Efficiency: Offer a system with a low initial investment that continues to save you money. The simplified design ensures ultra-low operating and maintenance costs over time.
Customizable Options & Configurations
Each unit to seamlessly fit into your existing production line:
- Premium Materials: Choose from #304 or #316 Stainless Steel for corrosion resistance, or abrasion-resistant steel for harsh environments.
- Sanitary Designs: Specialized construction, guards, and high-grade finishes specifically designed for food-grade and hygienic applications.
- Optional Accessories: Enhance your system with integrated stainless steel support structures, specialized cleaning spraylines, and custom collection troughs.
Versatile Industrial & Municipal Applications
Trusted across a diverse range of demanding sectors:
- Food & Beverage Processing: Ideal for food process effluent, seafood processing rinse water, and rendering processes.
- Pulp, Paper & Textiles: Used for fiber and pulp recovery, as well as tannery effluent solids removal.
- Waste & Water Management: Perfect for municipal wastewater treatment, sludge/scum thickening, grit-from-rock separation, and removing hazardous solids from environmental remediation sites.
- General Manufacturing: Efficiently handles the removal of extruded pellets from cooling baths and separates debris from various plant and equipment-cleaning processes.
Why Choose Rotating Drum Screens?
Engineered with the rotating drum as the single moving part, this system virtually eliminates mechanical wear and unexpected downtime. By combining a low initial investment with ultra-low operating costs and a continuous self-cleaning mechanism, it delivers a highly reliable, hassle-free filtration solution that ensures a rapid return on investment.
Unlike traditional, bulky separation equipment, its compact design easily integrates into tight spaces with limited headroom, saving you from costly structural modifications. It provides exceptional solid-liquid separation—even for oily or fibrous materials—allowing you to recover valuable products from your process streams while significantly reducing waste disposal costs.
Rotating Drum Screen Model 24-RDS-72-SS
Featuring a high-capacity wedgewire cylinder measuring 24 in. (61 cm) in diameter and 72 in. (183 cm) in length, this model delivers powerful separation at flow rates from 600 to 2,790 gal/min (2,270 to 10,560 liter/min). Its smart, energy-efficient engineering is specifically optimized to keep your horsepower and kilowatt requirements to a minimum.
Rotating Drum Screen Model 24-RDS-24-SS
Configured with a heavy-duty, corrosion-resistant stainless steel support structure.
Rotating Drum Screen Model 24×24
The 24 x 24 in. (61 x 161 cm) model features an automatic self-cleaning mechanism, efficiently separating solids and sludges from waste streams at flow rates up to 870 gal/min (3,293 liter/min) without any clogging.
Rotating Drum Screen No-Base Model
For maximum installation flexibility, Rotating Drum Screens can be supplied without a built-in base. This allows you to easily mount the unit directly onto existing tanks, process equipment, or custom user stands.
Operation Process
1-Even Distribution: Wastewater enters the system and flows evenly across the entire outside surface of the rotating drum.
2-Smart Separation & Self-Cleaning: The liquid drains through the small slots in the screen. Inside the drum, a special plate directs the filtered water to push back out through the bottom of the screen. This continuous inside-out flush keeps the screen clean automatically, preventing clogs even from sticky, oily, or fibrous materials.
3-Drying & Easy Discharge: The separated solids stay on the outside of the screen and quickly lose moisture, drying down to the 20% range. A scraper blade then gently removes these dry solids and guides them down the discharge chute.
