GN Separation, a provider of decanter centrifuges, recently supplied two of GNLW series dewatering decanter centrifuges for a municipal wastewater treatment project in Europe. Specifically, one unit each of the GNLW364 and GNLW454 models were chosen to handle the complex task of dewatering and thickening municipal sewage sludge. This project showcases the advanced capabilities and reliability of GN’s equipment in treating municipal and industrial wastewater.

The Role of GN’s Dewatering Decanter Centrifuges

GN Separation’s T Series dewatering decanter centrifuges, including the GNLW364 and GNLW454 models, are designed for efficient dewatering of municipal wastewater sludge, which often has fine particles and a high water content. These centrifuges are equipped with a beach angle of 8.5 degrees, providing a longer drying and dewatering zone that leads to superior dryness of the discharged solids. This feature is particularly beneficial for municipal applications, where high volumes of wastewater sludge must be processed while maintaining energy efficiency and operational stability.

The GNLW364 and GNLW454 are well-suited for large-scale municipal projects, offering higher treatment capacity and improved solid-liquid separation. The sludge processed by these units becomes significantly drier compared to traditional dewatering methods, reducing disposal costs and improving operational efficiency. This is especially important in municipal wastewater treatment plants, where minimizing waste and maximizing resource recovery is a priority.

Key Features of GN’s T Series Decanter Centrifuges

GN’s T Series decanter centrifuges offer several advantages that make them ideal for challenging dewatering tasks in wastewater treatment, including:

• Optimized Beach Angle: The 8.5-degree beach angle ensures a longer dewatering zone, which increases the efficiency of the dewatering process and results in drier solids.
• Durability: GN’s centrifuges feature duplex stainless steel (SUS2205 and SUS2304) components, offering excellent corrosion resistance and extended service life, even under harsh operating conditions.
• Enhanced Sludge Dryness: The centrifugal force generated by the centrifuges’ high-speed operation effectively separates the solids from the liquid, producing a high level of dryness, which is crucial for reducing waste volume.
• Energy Efficiency: GN’s decanter centrifuges are designed to minimize energy consumption while maximizing throughput, helping municipalities lower operating costs.

Advanced Technology and Customization

GN Separation’s dewatering decanter centrifuges are equipped with a range of advanced technologies to ensure smooth and reliable operation, such as:

• Automatic Monitoring System: Real-time monitoring of centrifuge parameters, including speed, vibration, and lubrication, helps optimize performance and prevent potential issues before they affect operations.
• Customizable Materials: GN offers a range of customizable materials for the centrifuges, allowing them to be adapted to specific application needs, such as dealing with higher viscosity or high-concentration sludge.
• Automatic Lubrication and Maintenance Features: The centrifuges include automatic lubrication systems, reducing maintenance workload and improving equipment longevity.

Versatility for a Variety of Applications

While this particular project focuses on municipal wastewater treatment, GN’s dewatering decanter centrifuges are also widely used in many other industries, including:

• Industrial Wastewater Treatment: Processing oily sludge, cutting fluids, and mineral washing water.
• Environmental Protection: Dewatering sewage, construction mud, and mine wastewater.
• Chemical and Food Industries: Handling organic wastewater, precision casting wastewater, and even salt crystal clarification.

At GN Separation, we specialize in providing high-quality equipment for liquid and solids separation across various industries. One of our key products is the Slant Plate Clarifier, also known as the Inclined Plate Clarifier, a highly efficient and cost-effective solution for clarifying liquids by separating suspended solids.

What is a Slant Plate Clarifier?

A Slant Plate Clarifier is a gravity-based liquid-solid separation equipment designed to remove particles from liquid streams. When a mixture of solids and liquids (which may or may not be flocculated) enters the clarifier’s inlet trough, it flows upward through a series of inclined plates. The solids in the mixture settle on the plate surfaces, sliding down by gravity into a sludge collection hopper. The clarified liquid then flows through orifice holes and exits at the top of the clarifier.

Advantages Over Traditional Systems

Compared to conventional settling tanks, the Slant Plate Clarifier offers several distinct advantages:

• Smaller Footprint: The inclined plates increase the effective settling area, allowing for efficient solids separation in a compact space.
• Cost-Effective: It offers a more affordable solution than traditional settling tanks, with a significantly smaller footprint for the same processing capacity.
• Energy Efficient: The Slant Plate Clarifier operates using gravity, requiring minimal power for the separation process compared to more energy-intensive systems like decanter centrifuges.
• Low Maintenance: With fewer moving parts, especially in comparison to decanter centrifuges, the Slant Plate Clarifier is easy to maintain. The only mechanical component that may require attention is the auger that helps transfer sludge.
