GN Separation has finished full manufacturing and pre-shipment factory preparation of a complete integrated sludge dewatering system for a European client. The packaged solution consists of the GNDL303 Sludge Dewatering Screw Press and GNSJY3000 Chemical Dosing Unit, all of which have passed full production and factory acceptance inspections and are ready for delivery to the client’s project site. Featuring a compact, fully automated and highly reliable design, the system enables continuous sludge conditioning, thickening and dewatering for standardized wastewater treatment workflows.

The GNDL303 Sludge Dewatering Screw Press is a cost-effective, environmentally friendly mechanical dewatering solution suitable for diverse sludge types. It adopts screw extrusion technology to achieve steady, continuous solid-liquid separation. During operation, the rotating screw conveys sludge forward, where gradual compression is generated through variable internal cavity geometry. Combined with precise gaps between fixed and floating ring assemblies, the increasing extrusion force separates free water from sludge while retaining solid particles stably. The entire dewatering and thickening process runs continuously with simple operation and minimal manual involvement.

To enhance flocculation and dewatering efficiency, raw sludge is conditioned with polymer flocculants before entering the screw press, which optimizes floc formation and accelerates internal water release. Tailored to the technical requirements of this European project, the GNSJY3000 Chemical Dosing Unit is fully integrated into the system to ensure accurate, stable preparation and dosing of polymer conditioning agents.

The GNSJY3000 is an automatic dry powder dosing system engineered for precise polymer solution preparation, maturation and storage. Constructed entirely from stainless steel, the equipment features a multi-stage structural design to independently complete proportioning, stirring, maturation and storage. Dry polymer powder and water are accurately metered and fully mixed in the preparation stage to form a homogeneous solution, which is then transferred to the maturation tank for sufficient reaction. After full maturation, the qualified solution is stored in the buffer tank and continuously supplied to the dewatering unit via dosing pumps.

This automated workflow ensures consistent polymer solution concentration and stable dosing volume, delivering uniform, high-quality sludge conditioning performance throughout continuous operation.

The combination of the GNDL303 screw press and GNSJY3000 dosing unit forms a complete, turnkey sludge dewatering system. Equipped with intelligent PLC automatic control, the system realizes unmanned management of core operational procedures, effectively reducing manual intervention and lowering long-term operation and maintenance costs. Its compact integrated structure saves floor space and simplifies cross-border transportation and on-site installation. The system only requires basic water, power and sludge pipeline connections for commissioning, greatly improving on-site deployment efficiency.

The system also features low-energy continuous operation, a key advantage over conventional high-speed dewatering equipment. Running at a low and stable rotational speed, the screw press cuts energy consumption and mechanical wear while maintaining consistent dewatering results. Separated filtrate can be safely discharged or recirculated to the upstream treatment process, while dewatered sludge is continuously discharged for subsequent transportation, disposal or resource recovery.

With all manufacturing, testing and inspection works completed, the integrated sludge dewatering package is ready for shipment to Europe. GN Separation’s professional technical team will provide full after-sales support, including on-site installation guidance, system commissioning and operational debugging, to ensure stable and reliable long-term operation at the client’s facility.

This European project further demonstrates GN Separation’s strong capability in delivering customized turnkey sludge treatment solutions. By integrating mechanical dewatering, automatic chemical dosing and intelligent control into a compact, practical package, the company provides global clients with high-stability, cost-effective sludge management equipment.

Driven by continuous technological innovation in solid-liquid separation and abundant international project experience, GN Separation is dedicated to delivering efficient, reliable and economical sludge dewatering solutions for municipal wastewater treatment, industrial wastewater treatment and various sludge management applications worldwide.
