High-Performance Solid Bowl Decanter Centrifuge for Wastewater Treatment and Sludge Dewatering

Decanter Centrifuges Description

A decanter centrifuge, also known as a horizontal bowl centrifuge, solid bowl centrifuge or scroll centrifuge, is a machine used to separate a solid material from a liquid(s) using a high-speed and continual rotational process. While wastewater treatment of biosolids is a primary application, the separation of one solid material from one liquid (2-phase dewatering) in a slurry is also important for a number of industries including chemical, food, oil, and mining to name a few.

Decanter Centrifuges Structure

The typical decanter centrifuge consists of several key components:

Cylindrical Bowl: The main rotating vessel where separation occurs
Screw Conveyor (Scroll): A helical screw that rotates slightly faster or slower than the bowl to transport separated solids
Feed Zone: Where the mixture enters the centrifuge
Discharge Ports: Separate outlets for liquid and solid fractions
Drive System: Motors and gearboxes that power the rotation

Decanter Centrifuges Advantages

High-performance separation, resulting in high-value products and low waste management costs
Low energy consumption and carbon footprints
Low maintenance costs thanks to continuous operation, high-grade machine materials, smart design and well-thought preventive services
Low capital cost/capacity ratio
