Enclosed Rotary Drum Sludge Thickener FRDT-35
The FRDT-35 features a fully enclosed drum design that effectively contains odors, making it perfect for facilities with stringent environmental requirements, such as printing and dyeing plants. With a treating capacity of 20-35 m³/h and 95% solids capture, it enhances sludge concentration while maintaining a clean and hygienic environment.
Key Selling Points
- Odor-Free Operation: The fully enclosed drum prevents unpleasant smells from escaping, improving workplace conditions.
- Space-Saving Design: Compact footprint fits into limited installation spaces, ideal for retrofitting existing plants.
- High Efficiency: 95% solid capture ensures maximum sludge concentration, reducing downstream processing.
- Laboratory-Tested Performance: Proven in municipal and industrial applications, achieving solids concentration from 99.4% to 97% moisture content.
- Low Operating Costs: Minimal wearing parts and low-speed rotation reduce energy consumption and maintenance needs.

Models and Options
Available models in FRDT series: FRDT-20, FRDT-25, FRDT-35, FRDT-40, FRDT-50, FRDT-70, FRDT-80, and FRDT-100. Each model can be customized with different screen meshes and materials.
Materials and Structure
Constructed from SS304 stainless steel, the drum is fully enclosed to seal in odors. The design includes an integrated wash water system and flocculation tank, ensuring efficient polymer conditioning and continuous operation.
Applications
Especially recommended for printing and dyeing effluent, municipal wastewater, and other processes where odor control and limited space are critical. Also suitable for paper mills and industrial sludge thickening.
Customization
Customizable with various screen mesh sizes, SS316 material for corrosive sludge, explosion-proof components, and PLC controls. Our team can adapt the design to your specific site constraints.
Case Study
In a municipal WWTP, our enclosed rotary drum thickeners (FRDT series) were used to pre-concentrate sludge from 99.4% to 97% moisture content. The fully enclosed design maintained hygienic conditions, and the robust construction ensured stable performance with minimal wearing parts.
FAQ
- How does the enclosed design reduce odor? The drum is fully sealed, preventing release of VOCs and odorous gases.
- Is it suitable for very corrosive sludge? Yes, we offer SS316 upgrade for high corrosion resistance.
- Can it operate automatically? Yes, it supports continuous automatic operation via PLC control.
- What is the noise level? The slow-speed drum minimizes noise; typical below 70 dB.
- What is the warranty? Typically 12 months; please confirm with sales.
- How often should screens be replaced? Depending on sludge type; screens are durable and typically last several years.
- What is the minimum order? 1 unit.
