Overview

The document presents technical information on the Headworks® TurboDrum IN™ inclined drum screen, designed for municipal and industrial wastewater treatment applications. It highlights the equipment's design, operational principles, optional features, and application suitability.

Product Description and Design

• TurboDrum IN™ Inclined Drum Screen: Installed at a 35º angle in a channel or opening to maximize flow capacity and efficient screenings conveying.
• Operation: Process flow enters the internal diameter of the rotating drum and exits through screen elements to the outside. Longitudinal paddles carry screenings to the top for washing and discharge.
• Screen Openings: Available with slot openings ranging from 0.25 mm to 6 mm, including wedgewire, perforated plate, or wire mesh options.
• Flow Capacity: Handles flows up to 4600 m³/h (30 million gallons per day), suitable for small to medium wastewater treatment plants.

Key Features and Benefits

• Integrated Solution: Combines screening, conveying, compaction, washing, and optional bagging in a single unit powered by one motor.
• No Bypassing: Flow is directed inside the drum and exits outside, ensuring complete screening.
• Optional TurboWash™: A patented agitator that creates a turbulent mixing zone to loosen and emulsify organic BOD material on screenings, producing clean, fecal and odor-free screenings.
• Compact and Efficient: The integrated design reduces footprint and enhances operational efficiency.

Applications

• Smaller to medium-sized municipal wastewater treatment plants.
• Fine screening ahead of advanced treatment systems such as Membrane Bio Reactors (MBR), Moving Bed Biofilm Reactors (MBBR), and Integrated Fixed-Film Activated Sludge (IFAS).
• Scum screening.
• Water treatment plants.
• Industrial wastewater treatment facilities.

Technical Specifications

• Installation: Gravity-fed in-channel installation at 35º angle; can also be installed as a self-contained TurboTank™ system for pressure feed applications.
• Control: Operation cycle controlled by monitoring differential headloss across the screen.
• Dimensions and Flow Rates: Multiple models available (e.g., 0707, 0909, 1313, up to 2626) with flow capacities ranging from 170 m³/h to 4600 m³/h depending on slot opening size.
• Motor Power: Ranges from 0.75 kW to 3 kW depending on model size.

Performance Considerations

• Effective Flow Capacity (EFC): The chart provided relates EFC to Total Suspended Solids (TSS) and Fat, Oil, and Grease (FOG) content, assuming 100 mg/L FOG. Typical municipal wastewater has an EFC of 250 mg/L.
• Impact of Solids Quality: Solids concentration and FOG content significantly affect screening efficiency.

Optional Equipment

• TurboWash™ Agitator: Enhances cleaning of screenings by creating a turbulent zone that emulsifies organic BOD material, improving downstream treatment and reducing odors.

Summary

The Headworks TurboDrum IN™ inclined drum screen offers a robust, compact, and efficient solution for screening in municipal and industrial wastewater treatment. Its design supports high flow capacities with customizable screen openings and integrated washing and compaction. The optional TurboWash™ agitator further improves screenings quality by reducing organic load and odors. This equipment is well-suited for modern advanced treatment processes requiring high levels of screenings removal.
