Decanter centrifuge for wastewater treatment
Effectively manage waste streams and enhance resource recovery with this high-performance decanter centrifuge, designed to optimize solid-liquid separation and reduce operational costs in continuous processing environments.

Dewaters and Clarifies Wastewater Efficiently
The Flottweg C-series Decanter Centrifuge offers a robust solution for wastewater and sludge treatment, designed with Flottweg’s renowned engineering. Its unique dual-cone design enhances separation efficiency by compacting solids against a baffle plate, significantly optimizing the dewatering of municipal sewage and industrial waste. This centrifuge operates continuously, using the Simp Drive® system to independently control bowl and differential speeds for consistent throughput, even with variable feed conditions. The optionally integrated Recuvane® system allows for energy recovery, further reducing operational costs by up to 30%. Constructed with high-quality stainless steel and offering a comprehensive wear protection package, it ensures long-term durability and minimal maintenance. Ideal for applications in water treatment, bioplastics, and biofuel production, this equipment can process significant volumes with customizable rotor speeds and configurations, ensuring compliance with industry standards and seamless integration into existing systems.
