GN Separation has successfully completed the delivery of a tailor-made GNLW554 sludge dewatering centrifuge package for an overseas municipal wastewater treatment plant (WWTP). The full-set solution integrates a GNLW554 decanter centrifuge and an automatic chemical dosing unit, delivering one-stop, reliable support for full-process sludge conditioning and high-efficiency dewatering.
The entire sludge treatment workflow adopts an automated and streamlined operation logic to ensure stable and consistent treatment results. Initially, the automatic polymer dosing system precisely prepares and injects polymer solutions in strict accordance with actual operational demands, realizing uniform sludge flocculation and stable pre-conditioning effects. After sufficient conditioning, the sludge is conveyed into the GNLW554 decanter centrifuge. Driven by powerful high centrifugal force, the equipment achieves continuous and thorough solid-liquid separation. The whole process steadily outputs low-moisture dewatered sludge cake, while generating clear centrate that can be directly sent for subsequent wastewater treatment procedures.
Engineered for 24/7 continuous operation in rigorous WWTP working conditions, the GNLW554 decanter centrifuge features an optimised bowl and screw conveyor structure, which guarantees superior and stable separation efficiency. Key wearing parts are equipped with professional wear-resistant protection, effectively extending the equipment’s service life and reducing frequent maintenance costs. Matched with the intelligent automatic polymer dosing unit, the complete dewatering package delivers outstanding operational stability, significantly cuts chemical reagent consumption, and lowers the overall operational cost of sludge treatment.

GN Separation has completed the manufacture and delivery of a 14-inch sludge dewatering centrifuge package for a client in Southeast Asia. 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.

2026.06.03 Polymer dosing unit 1000L

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

BenefitDetail
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

Outperforming conventional sludge dewatering equipment, the GN screw press features low energy consumption, fully automated operation, stable long-term performance, and simple daily maintenance. Its versatile adaptability allows wide application in municipal sewage treatment, industrial wastewater treatment, oil sludge disposal, food processing, chemical production and other industrial sectors.
The complete GN screw press dewatering system is composed of 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 on-site reuse or discharged compliantly in accordance with project and environmental standards.

 Automatic Polymer Chemical Dosing Unit

2025.05.26 Polymer Dosing Unit

Matched with the screw press dewatering system, GN’s self-developed au
tomatic chemical dosing unit was also included in this shipment, serving as a core supporting facility for continuous, standardized polymer chemical preparation and dosing. The entire unit adopts stainless steel construction for corrosion resistance and long service life, with an integrated three-chamber structure covering solution preparation, curing and storage stages.
The unit features simple operation and full-process automation. 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 uniform and thorough mixing. It then flows into the curing chamber for sufficient maturation and homogenization, before transferring to the storage chamber. The fully prepared chemical solution can be automatically and accurately delivered to dosing points via supporting dosing pumps.
This intelligent dosing system effectively reduces manual intervention and human error, improves the efficiency and consistency of chemical preparation, and ensures stable and reliable dosing accuracy throughout the sludge dewatering process, optimizing the overall treatment effect.
