Solid bowl decanter centrifuges continuously separate solids from liquids by spinning a cylindrical bowl at high speeds, with an internal screw conveyor transporting solids toward the discharge end. These machines are ideal for handling slurries with moderate to high solids content and are essential for industries requiring high-throughput, continuous operation.

Primary uses across industries

• In wastewater treatment, decanter centrifuges dewater sludge efficiently and reliably.
• In chemical manufacturing, they separate fine particles from chemical slurries and recover valuable products.
• In food and beverage production, they clarify juices, recover starches, and process food waste.
• In oil and gas industries, they separate drilling muds, oily sludge, and produced water streams.
• In biotechnology and pharmaceuticals, they harvest biomass and clarify fermentation broths.

Types of materials processed

• Slurries with moderate to high solids concentrations
• Fine particles, biological materials, and fibrous solids
• Oil-water-solid mixtures requiring three-phase separation (in specialized models)
• Industrial and municipal sludge

Common materials of construction

Solid bowl decanter centrifuges are built for durability, chemical compatibility, and heavy-duty operation:

• Stainless steel for sanitary and corrosion-resistant applications
• Hastelloy or duplex stainless steel for aggressive chemical environments
• High-strength carbon steel for standard industrial and wastewater operations

Key features of solid bowl decanter centrifuges

• Continuous operation with automatic solids discharge
• Adjustable differential speeds for optimal separation performance
• Robust designs to handle abrasive or high-solids feed streams
• Options for two-phase or three-phase separation (solids-liquid-liquid)
• Efficient, compact design for space-saving installation
