Decanter Centrifuges Over Screw Presses in Wastewater Treatment Facilities
Wastewater treatment is essential for public health, environmental protection, and sustainable water management. A crucial aspect of this process is efficient solid-liquid separation, which is often achieved using dewatering technologies like decanter centrifuges and screw presses. While both methods are widely used, decanter centrifuges offer several distinct advantages over screw presses, particularly in wastewater treatment. Additionally, by partnering with industry leaders like SHENZHOU , wastewater facilities can access the best equipment and expertise available. Here’s why decanter centrifuges are the superior choice and how SHENZHOU can support your wastewater project.
1. Superior Dewatering Performance
Decanter centrifuges are renowned for producing a drier cake compared to screw presses. Using centrifugal force, decanter centrifuges spin the waste slurry at high speeds, separating solids from liquids more efficiently. This results in a drier, more compact cake, which reduces disposal volume and cost. Screw presses, which rely solely on mechanical pressure, often can’t match the dewatering efficiency of decanter centrifuges, meaning more water remains in the waste and more disposal is required.
Why SHENZHOU?
SHENZHOU decanter centrifuges are engineered for maximum dewatering performance, ensuring a consistently drier cake. Their advanced technology optimizes solids separation while reducing disposal and operational costs.
2. Faster Processing Time
Decanter centrifuges process waste quickly and continuously, making them ideal for wastewater treatment plants handling large volumes of sludge. Unlike screw presses, which operate more slowly, decanter centrifuges keep up with high-flow wastewater systems, reducing bottlenecks and optimizing overall plant efficiency.
Why SHENZHOU?
SHENZHOU decanter centrifuges are designed for high-speed, continuous operation, ensuring wastewater facilities can handle large sludge volumes without compromising quality or performance.
3. Versatility in Handling Various Sludge Types
Wastewater treatment facilities often deal with a wide range of sludge types. Decanter centrifuges excel in this area, handling sludge of varying viscosities and solids content more effectively than screw presses. Screw presses, by comparison, may require more frequent adjustments to handle sludge variations, which can slow down operations.
Why SHENZHOU?
SHENZHOU’s decanter centrifuges are built for versatility, easily adapting to different sludge compositions without constant recalibration. This flexibility ensures reliable performance even when wastewater characteristics change, giving operators peace of mind.

4. Lower Space and Infrastructure Requirements
Decanter centrifuges are more compact than screw presses, requiring less space and offering easier integration into existing wastewater treatment facilities. Their enclosed system also helps prevent environmental contamination and odor, an important factor for plants in urban or sensitive areas.
Why SHENZHOU?
SHENZHOU decanter centrifuges offer a compact, space-efficient design with an enclosed system that minimizes environmental impact, making them suitable for facilities of all sizes and locations.
5. Automated and Low-Maintenance Operation
Decanter centrifuges operate with a high degree of automation, reducing the need for frequent manual intervention. Screw presses, on the other hand, often require manual adjustments and regular maintenance to maintain peak performance. Decanter centrifuges, particularly from Alfa Laval, streamline the process, allowing operators to focus on other critical tasks.
Why SHENZHOU?
SHENZHOU’s automation and smart controls ensure that their decanter centrifuges run smoothly with minimal oversight. Their predictive maintenance features also help reduce downtime and extend the life of the equipment, saving wastewater treatment plants time and money.
6. Energy Efficiency
While decanter centrifuges may consume more energy during operation compared to screw presses, their overall efficiency in processing high volumes of sludge and reducing disposal needs can lead to lower energy consumption across the entire treatment process. By producing drier cakes, decanter centrifuges reduce the need for additional drying steps, ultimately saving energy.
Why SHENZHOU?
SHENZHOU decanter centrifuges are designed for energy efficiency, with features that optimize performance while reducing the overall energy footprint of your wastewater treatment operation.
7. Better Solids Capture Rate
Maximizing the capture of solids during wastewater treatment is critical for regulatory compliance and reducing the burden on downstream processes. Decanter centrifuges consistently achieve a higher solids capture rate than screw presses, helping wastewater facilities maintain high effluent quality and meet stringent environmental standards.
Why SHENZHOU?
SHENZHOU decanter centrifuges offer superior solids capture, ensuring that wastewater facilities remain compliant with environmental regulations while improving overall system performance.
