Sludge Dewatering Screw Press Package Ready for Shipment to European Client (GNDL303 + GNSJY3000)

We are pleased to announce that a complete set of sludge dewatering screw press package, tailored for a European client’s municipal and industrial wastewater treatment project, has fully completed factory assembly, systematic testing, quality inspection and standardized packaging. The entire equipment package is now ready for sea shipment and will be delivered to the European site on schedule to support the customer’s on-site sludge treatment commissioning and formal operation.
This turnkey dewatering system integrates core dewatering equipment and supporting chemical dosing units, covering the full process from sludge flocculation conditioning to automatic squeezing dewatering. It is a high-efficiency, energy-saving and fully automatic solid-liquid separation solution specially optimized for low-concentration, high-viscosity and fine-particle sludge commonly found in European sewage treatment scenarios. The whole system features stable operation, low operating cost and zero blockage risk, which perfectly meets the local environmental protection discharge and sludge reduction standards.

Complete Equipment Configuration List

The full shipment package consists of two core pieces of equipment: GNDL303 Multi-plate Screw Press and GNSJY3000 Automatic Chemical Dosing Unit, forming a matched and integrated sludge dewatering system.

1. GNDL303 Sludge Dewatering Screw Press

The GNDL303 screw press is a mature and high-capacity model in our multi-plate dewatering equipment series, specially designed for continuous and automatic sludge thickening and dewatering. The whole machine adopts full 304 stainless steel structure, which is anti-corrosion, wear-resistant and adaptable to various complex sludge conditions including municipal sewage sludge, food processing sludge, chemical industrial sludge and aquaculture wastewater sludge.
Adopting low-speed screw extrusion technology, the equipment runs at a low rotation speed with minimal vibration and ultra-low noise, realizing 24-hour unattended automatic operation. The unique self-cleaning overlapping plate structure effectively solves the common blockage problem of traditional dewatering machines, eliminating frequent manual cleaning and reducing water and power consumption. With stable solid-liquid separation performance, it can efficiently reduce the moisture content of sludge cake, greatly lowering sludge transportation and disposal costs for European customers.

2. GNSJY3000 Automatic Chemical Dosing Unit

Matched with the GNDL303 screw press, the GNSJY3000 automatic chemical dosing unit is a professional polymer preparation and feeding system. It realizes automatic water feeding, quantitative powder dosing, cyclic stirring and mature flocculant solution output, ensuring the precise concentration of the medicament required for sludge conditioning.
In the sludge dewatering process, fine sludge particles cannot be effectively separated by physical extrusion alone. The GNSJY3000 dosing unit accurately mixes and dilutes the polymer agent, fully reacts with the incoming sludge to aggregate fine suspended particles into dense and large flocs. This process significantly improves the water permeability and dewatering efficiency of the sludge, laying a key foundation for the screw press to achieve high-standard dewatering effects. The equipment features intelligent frequency conversion control, stable dosing volume and no medicament waste, effectively reducing the overall operating cost of the production line.

Core Advantages of the Integrated Dewatering System

This matched package of GNDL303 screw press and GNSJY3000 dosing unit has outstanding comprehensive advantages in European environmental protection projects:
  • Full Automatic Operation: The whole system realizes one-key start and continuous automatic operation, with no need for full-time staff on duty, saving labor costs greatly.
  • Energy Saving and Low Consumption: Low-speed extrusion design reduces power consumption; the self-cleaning structure saves flushing water, meeting Europe’s energy-saving and emission-reduction requirements.
  • No Blockage & Low Maintenance: The flexible gap self-cleaning structure avoids sludge clogging, with low failure rate and simple daily maintenance.
  • Wide Adaptability: It can stably handle various types of organic and industrial sludge, with strong adaptability to fluctuating sludge water content and concentration.
  • Compact & Space-saving: Integrated skid-mounted design occupies small floor space, which is friendly to European plant sites with limited space.

A Batch of GNSP20B Solids Vacuum Pump Ready for Shipment

GN Solids Control recently completed the production of a batch of GNSP20B Solids Vacuum Pumps, which are ready for shipment to support industrial solids transfer applications.

GN Solids Vacuum Pump, also known as sludge vacuum pump, is a fully pneumatic-powered vacuum loading and solids transfer system designed for handling solids, powders, slurry, sludge, and other difficult materials. Driven only by compressed air, the pump provides a safe and efficient solution for applications where electrical equipment is not suitable, especially in oil & gas, mining, and hazardous environments.

The GNSP20B model is a compact and robust solids transfer pump with strong suction capability up to 25″Hg vacuum and a conveying distance of more than 500 meters. GN Solids Vacuum Pumps are available in different capacities, including 10 m³/h, 20 m³/h, and 40 m³/h, while customized skid-mounted group pump units can also be designed according to project requirements.

The working principle is based on alternating vacuum loading and positive pressure discharge. Compressed air creates vacuum inside the pump tank to draw materials through the suction line. After loading, the air direction changes to pressurize the tank and transfer materials through the discharge pipeline.

GN Solids Vacuum Pumps are widely applied in tunneling and TBM projects, mining slurry transfer, thickener de-sludge cleaning, drilling cuttings transfer, tank cleaning, tailings handling, industrial waste recovery, and other heavy-duty material transfer operations.

With a compact design, reliable performance, and explosion-proof capability, GN Solids Vacuum Pump provides an efficient solution for challenging industrial cleaning and solids handling tasks.

Sludge Dewatering Screw Press Package Ready for Shippment to Europe Client

GN SOLIDS CONTROL is pleased to announce that a sludge dewatering screw press package is ready for shipment to a European client. The package includes a GNDL303 Screw Press and a GNSJY3000 Chemical Dosing Unit, providing an integrated and automated solution for efficient sludge dewatering and chemical preparation.

The GN GNDL303 Screw Press uses the principle of screw extrusion to achieve solid-liquid separation through the gradual reduction of screw pitch and filtration gaps. During operation, sludge is first concentrated by gravity and then continuously conveyed into the dewatering section, where increasing internal pressure further reduces sludge volume and removes filtrate.

The moving and fixed rings work together to maintain the filtration gaps while the moving rings continuously clean the screen surface, helping prevent clogging and ensuring stable operation. The system is suitable for a wide range of sludge concentrations and offers low energy consumption, compact structure, and easy maintenance.

The GNSJY3000 Chemical Dosing Unit prepares, dissolves, and stores flocculant automatically before delivering the prepared solution to the dosing point. With PLC-based automatic control, corrosion-resistant materials, and integrated preparation, curing, and storage functions, the unit provides reliable and consistent chemical dosing.

This shipment further demonstrates GN SOLIDS CONTROL’s capability to provide customized and integrated sludge dewatering solutions for wastewater treatment applications worldwide.
