Meeting increasingly strict discharge regulations while controlling sludge disposal costs is a critical challenge for industrial wastewater treatment plants. Peony Separation delivers engineered separation solutions combining decanter centrifuges, auxiliary separation equipment, and process expertise to reduce sludge volume, optimize polymer consumption, and support long-term regulatory compliance.

Key Application Scenarios

Our separation solutions are widely applied in the following wastewater treatment processes:

• Municipal Sewage: Primary and secondary sludge dewatering for municipal wastewater treatment plants.

• Industrial Wastewater:Paper & pulp sludge and black liquor;Leather and tannery wastewater;Printing and dyeing effluents

• ZLD Pre-treatment: Brine and wastewater concentration prior to MVR evaporation systems.

• Lower OpEx (Operating Expense): Optimized scroll design delivers drier solids (high DS content), reducing transportation and disposal costs by up to 30%.
• Wear Protection: Critical components (scroll flights, solids discharge port) are protected by Tungsten Carbide tiles for extended service life in abrasive environments.
• Intelligent Control: Fully automated PLC system with VFD control ensures stable operation under fluctuating feed conditions.

In industrial wastewater treatment, decanter centrifuges are the most widely used solution. They are designed for continuous solid-liquid separation and can handle high solids content, variable sludge properties, and large flow rates, making them ideal for municipal and industrial wastewater applications.

A centrifuge applies high centrifugal force to rapidly separate solids from liquid. Compared with traditional methods, centrifuge systems achieve higher dry solids content, reduce sludge volume, and significantly lower transportation and disposal costs while maintaining stable, continuous operation.

Yes. Centrifuge systems are widely used for municipal sewage, paper and pulp wastewater, printing and dyeing wastewater, tannery wastewater, and high-salinity or oily wastewater. With proper conditioning and flocculation, the system can adapt to different sludge characteristics.

Centrifuges are commonly used as pre-treatment equipment for ZLD systems. By removing suspended solids before MVR evaporation, centrifuges help protect downstream equipment, reduce fouling, and improve overall system reliability and energy efficiency.

Compared with filter presses, centrifuge systems offer continuous operation, smaller footprint, lower labor requirements, and faster startup. They are especially suitable for large-scale wastewater treatment projects where stable operation and automation are critical.
