The project underscores GN’s proven capability in delivering integrated solid-liquid separation solutions for both municipal and industrial wastewater treatment.

2026.06.03 Sludge dewatering centrifuge 14 inch

Meeting Tighter Environmental Standards

Across Southeast Asia, increasingly strict discharge regulations are driving wastewater treatment facilities to adopt more efficient and reliable technologies — particularly for handling complex sludge conditions. Removing fine and ultrafine suspended solids has emerged as a critical challenge in achieving stable effluent quality while keeping treatment costs under control.

Integrated Solution: Centrifuge + Chemical Dosing

GN supplied a complete sludge dewatering system built around a 14-inch high-speed decanter centrifuge, paired with a 1,000L polymer dosing unit. The design integrates chemical conditioning with centrifugal separation to treat difficult wastewater streams more effectively.

Conventional mechanical separation typically handles particles in the 2–5 micron range. By injecting polymer into the sludge stream, the dosing unit promotes aggregation of fine and ultrafine particles into larger flocs. These flocs are then efficiently captured under high centrifugal force inside the decanter — significantly boosting solid-liquid separation performance.

Key Benefits for the Customer

Benefit Detail
Finer particle removal Polymer-enhanced flocculation captures particles below the conventional 2–5 micron threshold
Lower sludge moisture Drier discharged cake reduces transport and disposal costs
Operational stability Integrated skid-mounted design simplifies installation into existing systems
Regulatory compliance Improved effluent quality supports stricter discharge standards

Compact, Skid-Mounted, Ready to Deploy

The 14-inch decanter centrifuge targets small to medium-capacity sludge treatment applications, balancing separation efficiency, reliability, and energy consumption. Its compact skid-mounted configuration allows straightforward installation and easy integration with existing treatment infrastructure — making it suitable across a broad range of industrial settings.

GN Screw Press Sludge Dewatering Machine

The GN screw press sludge dewatering machine is a cost-effective, eco-friendly solution tailored for diversified sludge treatment scenarios. Adopting a mature screw extrusion solid-liquid separation principle, the equipment achieves continuous sludge thickening and deep dewatering through the powerful extrusion force generated by variable screw diameters and pitches, combined with the precise micro-gap filtration between fixed and moving rings.
Outperforming conventional sludge dewatering equipment, the GN screw press features low power consumption, fully automated operation, stable running performance, and simple daily maintenance. Its versatile adaptability enables wide application in municipal sewage treatment, industrial wastewater treatment, oily sludge disposal, food processing, chemical production and other industries.
The complete GN screw press dewatering system comprises a full-automatic control cabinet, flocculation conditioning tank, integrated sludge thickening and dewatering unit, and filtrate collection tank. Equipped with advanced intelligent control technology, the system supports automatic flocculant preparation and uninterrupted continuous dewatering operation. The treated filtrate can be either recycled for reuse or discharged up to standard, complying with diverse project environmental requirements.

Automatic Polymer Chemical Dosing Unit

2025.05.26 Polymer Dosing Unit

Supporting the screw press dewatering system, GN Separation also delivered a customized automatic chemical dosing unit, which is professionally designed for continuous, efficient and stable polymer chemical preparation and dosing. The entire unit is constructed of high-quality stainless steel and adopts a three-chamber integrated structure, including independent preparation, curing and storage compartments to ensure graded and thorough chemical dissolution.
The unit features simple and intelligent operation. On-site operators only need to add dry powder chemicals to the preparation tank and start the system. The chemical-water mixture first enters the stirring and dissolving chamber for full homogenization, then flows into the curing chamber for sufficient maturation to stabilize chemical activity, and finally transfers to the storage chamber. The well-prepared chemical solution can be automatically and quantitatively delivered to the dosing points via supporting dosing pumps.
This automated dosing system effectively reduces manual intervention and labor costs, improves the efficiency and accuracy of polymer preparation, and maintains consistent dosing stability throughout the sludge treatment process, laying a solid foundation for standardized and high-efficiency sludge dewatering.

GN’s Global Strength in Sludge Treatment Solutions

Boasting extensive practical experience in global sludge dewatering and solid-liquid separation projects, GN Separation has always adhered to reliable product quality, professional technical services and continuous technological innovation.

2026.05.21 GN banana screen on site

The Banana Screen features a multi-stage broken-line screen surface with progressively changing angles. The steeper inclination at the feed end accelerates material movement and enables rapid stratification — ideal for screening easily separable particles. As the angle gradually decreases toward the discharge end, the material flow slows, increasing the probability of successful screening and markedly boosting overall efficiency.

Proven Capability, Global Reach

Backed by reliable product quality and deep expertise in mining and mineral separation, GN continues to deliver professional screening and separation solutions to customers worldwide. The successful commissioning of more than 10 sets of GN vibrating screens at this domestic ilmenite mine further validates GN’s ability to manage large-scale mineral processing projects and provide equipment solutions that are efficient, stable, and cost-effective.
