Sludge Dewatering Screw Press Package Ready for Shipment to Europe Client

GN  factory has completed full assembly, functional inspection and packaging for a complete sludge dewatering package ordered by one European wastewater treatment client. This integrated solution consists of GNDL303 Sludge Dewatering Screw Press and GNSJY3000 Chemical Dosing Unit, and is now fully prepared for ocean shipment to the overseas project site.
Sludge volume reduction is a core challenge for municipal and industrial wastewater facilities across Europe. Rising disposal costs and strict local environmental regulations push plant operators to seek compact, low‑energy and automatic dewatering alternatives, instead of traditional belt filter presses or filter presses. The GNDL303 screw press is selected for this project to handle continuous sludge thickening and mechanical dewatering.
The GNDL303 adopts screw extrusion working principle. Conditioned sludge flows into the machine, and the low‑speed rotating screw pushes materials forward. Gradually decreased screw pitch and narrow gaps between fixed and moving rings build up extrusion pressure. Free water is separated out as filtrate through ring gaps, while solid particles are concentrated and discharged as dewatered sludge cake. Moving rings move up‑down to realize self‑cleaning, effectively preventing clogging. Compared with high‑speed centrifuges, this screw press features low noise, low power consumption and simple daily maintenance.
To guarantee stable dewatering output, the package is matched with GNSJY3000 Chemical Dosing Unit. Made of corrosion‑resistant stainless steel, this three‑chamber unit automatically finishes polymer powder feeding, mixing, maturation and storage. It prepares uniform flocculant solution and delivers accurate dosage to sludge pipeline. Proper flocculation turns fine sludge particles into firm flocs, greatly improving solid‑liquid separation efficiency. PLC automatic control reduces manual operation and keeps consistent chemical concentration during long‑time running.
This turn‑key package features small footprint and high automation. After arriving on‑site, clients only need to complete water, power and sludge pipeline connection for commissioning. Filtrate can flow back to upstream treatment system, and dewatered sludge cake is ready for transportation and final disposal. Before delivery, every key component has passed strict factory test to satisfy European market requirements.
This shipment marks another successful delivery of our integrated sludge treatment solution for European customers. Our team will keep offering remote technical guidance for installation, commissioning and operation support after equipment arrival. We keep supplying reliable screw press and supporting packages for global municipal and industrial wastewater projects.

GN Hydraulic Drive Centrifuge Unit for Diamond Core Drilling In Australia

Diamond Core Drilling operations demand precse solids control to maintain drilling fluid quality and protect expensive core bits. GN Solids Control, a leading manufacturer of solids control equipment, recently delivered a specialized hydraulic drive centrifuge unit to an Australian exploration client. This shipment underscores the company’s growing presence in the Asia-Pacific region and its capability to deliver tailored solutions for remote drilling operations.

Full Hydraulic Drive Centrifuge Technology

At the core of the supplied system is the GNLW223D-FHD Hydraulic Drive Centrifuge, engineered specifically for diamond core drilling applications. Unlike traditional electric-driven models, this unit operates entirely on hydraulic power, making it ideal for integration with drilling rigs already equipped with hydraulic systems. The centrifuge achieves a cutting point of 2–5 microns and delivers a processing capacity of 50–100 GPM, effectively removing ultra-fine solids that would otherwise accelerate bit wear and reduce core recovery quality.

The full hydraulic drive configuration provides independent, continuous control over both bowl speed and scroll differential speed. Operators can adjust parameters in real time to match changing mud conditions, ensuring optimal separation efficiency across varying drilling formations. The bowl rotates at speeds up to 3400 RPM, generating sufficient G-force to separate fine solid particles from the drilling fluid slurry. Key wear components—including the screw conveyor with tungsten carbide tile protection and solids discharge ports with tungsten carbide inserts—are built for extended service life in abrasive drilling environments.

Complete Solids Removal System Configuration

The Australian package includes a comprehensive solids removal unit designed for trailer-mounted deployment. The system features a 6 m3 mud tank with a compact skid structure, allowing easy transport between exploration sites. Two GN40ZJL-25-FHD feeding and discharge pumps handle fluid circulation, while a GNSLD-260 mixing hopper supports rapid mud preparation when new drilling fluid is required. Additionally, two mud guns are installed to prevent solids settling and maintain uniform mud properties within the tank.

Driven by a diesel-hydraulic power unit generating 40 kW total power, the entire system operates independently of grid electricity—a critical advantage for remote exploration locations across the Australian outback. The centrifuge processes drilling fluid directly from the drill collar, separating drill solids from the mud slurry before returning clean fluid to the active system. This closed-loop configuration reduces water consumption, minimizes waste disposal volumes, and ensures consistent mud weight and viscosity throughout the drilling program.
