The Pros and Cons of Disc Stack Centrifuges vs. Decanter Centrifuges

The Pros and Cons of Disc Stack Centrifuges vs. Decanter Centrifuges 1

In the world of industrial processes, separation is a crucial part of many operations. There are various separation methods, and two of the most popular are disc stack centrifuges and decanter centrifuges. Both types of centrifuges separate solids and liquids, but they do so in different ways. To determine which centrifuge is best suited for a particular process, it is essential to understand the pros and cons of each type.

Design and Operation

Disc stack centrifuges are designed to separate fluids with different densities. They create centrifugal force from the high-speed rotation of a set of stacked discs, each with an opening in the center. The fluid is fed into the center of the rotating discs, and the centrifugal force pushes the denser particles toward the outer edges, while the lighter particles move towards the center and are collected through a separate outlet.

Decanter centrifuges, also known as solid bowl centrifuges, separate liquids and solids using a rotating cylindrical bowl with a screw conveyor inside. The mixture is fed into the center of the bowl at a high speed, and the solids are pushed towards the inner diameter by the centrifugal force. The screw conveyor moves the solids to the discharge end of the bowl, while the liquids are discharged over a weir at the other end.

The operation of decanter centrifuges is more robust than disc stack centrifuges and can handle a broader range of densities. However, disc stack centrifuges are more efficient at separating fine solids and can achieve higher speeds, allowing for faster separation of liquids with a higher degree of purity.

Size and Capacity

The size and capacity of a centrifuge play a crucial role in selecting the right type for an application. Decanter centrifuges are larger and can handle a more considerable amount of solids and liquids. They are more suitable for large-scale industrial processes and require more space. Disc stack centrifuges, on the other hand, are smaller and more compact, making them ideal for laboratory and pilot-scale applications.

Maintenance and Operation Costs

The cost of maintaining and operating a centrifuge can significantly impact the total cost of a process, so it is essential to consider these costs when selecting a centrifuge type.

Decanter centrifuges are more complex and require more maintenance than disc stack centrifuges. They have more moving parts and are more prone to wear and tear. However, decanter centrifuges can operate continuously for extended periods, which minimizes downtime and increases efficiency. Disc stack centrifuges are easier to maintain and operate but require more frequent cleaning and sterilization, which can impact productivity and increase costs.

Environmental Impact

The environmental impact of a centrifuge type is another critical consideration. Decanter centrifuges require more energy to operate, resulting in higher energy costs and higher CO2 emissions. They also generate more waste and require more space, which can have a negative impact on the environment. Disc stack centrifuges, on the other hand, are more energy-efficient and generate less waste, making them a more environmentally friendly option.


Choosing the right centrifuge type for a particular application is essential to ensure efficiency, productivity, and cost-effectiveness. Deciding between disc stack centrifuges and decanter centrifuges requires careful consideration of various factors, including design and operation, size and capacity, maintenance and operation costs, and environmental impact.
