FRDT-20 Rotary Drum Sludge Thickener

The FRDT-20 is a compact rotary drum sludge thickener designed for low-solids sludge thickening in municipal and industrial wastewater treatment. With a treating capacity of 7.5-20 m³/h and a solid capture rate of 95%, it efficiently increases sludge concentration, reducing downstream load. Constructed in SS304, the enclosed drum design ensures hygienic and odor-free operation.

Key Selling Points

• High Capture Efficiency: 95% solid capture rate minimizes solids loss, maximizing sludge recovery and reducing disposal volume.
• Compact and Enclosed Design: Saves space and contains odors, making it suitable for indoor installations with limited footprint.
• Corrosion-Resistant Construction: SS304 material withstands corrosive environments, ensuring long-term reliability with minimal maintenance.
• Easy Integration: Continuous low-speed operation (around 10 rpm) and simple controls allow seamless integration into existing sludge treatment lines.
• CE Certified: Complies with EU Machinery and EMC directives, facilitating deployment in European projects.

Technical Specifications

Models and Options

FRDT series includes FRDT-20, FRDT-25, FRDT-35, FRDT-40, FRDT-50, FRDT-70, FRDT-80, and FRDT-100, offering capacities from 7.5 to 100 m³/h. Each model can be configured with various screen mesh sizes and material options for customized performance.

Materials and Structure

Constructed with SS304 stainless steel for all wetted parts, the FRDT-20 features an enclosed drum structure that prevents splashing and odor release. The drum rotates slowly to gently flocculate and thicken sludge, minimizing wear and energy consumption.

Applications

Ideal for municipal wastewater treatment plants, industrial wastewater facilities, paper mills, printing and dyeing operations, and sludge thickening projects where low-solids sludge needs to be pre-concentrated before dewatering.

Customization

SFC offers customization options including different screen mesh sizes (30-80 mesh), material upgrades (e.g., SS316 for highly corrosive sludge), and integrated control systems. Contact our sales team to discuss your specific requirements.

Case Study

A municipal WWTP in China installed 8 FRDT rotary drum thickeners to pre-concentrate raw sludge from 99.4% to 97% moisture content, increasing solids to 3%. This enhanced the downstream plate-and-frame filter press performance, achieving stable and efficient operation with minimal wear parts.

FAQ

1. What is the minimum order quantity? MOQ is 1 unit.
2. What are the payment terms? 30% deposit in advance, 70% balance before shipment.
3. How does the thickening process work? Sludge is conditioned with polymer, then fed into the rotating drum where water is filtered out through the mesh, increasing solids concentration.
4. Can it handle industrial sludge? Yes, it is suitable for various industrial wastewaters including paper mills and printing.
5. What certifications does it have? It is CE certified and the company holds ISO 9001, ISO 14001, and ISO 45001.
6. What is the delivery method? FOB/CIF.
7. How much floor space is required? The compact design minimizes footprint; exact dimensions on request.
8. Can it operate continuously? Yes, it is designed for automatic continuous operation with low-speed drum rotation (around 10 rpm).
