The GN Screw Press Sludge Dewatering Machine is a modern, environmentally friendly solution designed for effective sludge management across diverse industries. This advanced dewatering equipment operates on the principle of screw extrusion, using powerful compression forces generated by variances in screw diameter, pitch, and the narrow gap between the floating and fixed rings. This robust design enables precise solid-liquid separation, making it a sustainable, cost-effective choice for sludge dewatering.

Key Components of the GN Screw Press Dewatering System

The GN Screw Press Dewatering Machine features a fully automated control cabinet, flocculation modulation box, sludge thickening and dewatering device, and liquid collection tank. This automated control technology enables seamless flocculation, thickening, and dewatering processes, returning or discharging the filtrate efficiently. This makes the machine easy to operate, even for large-scale sewage treatment projects in municipal, aquaculture, food processing, starch, oil, pharmaceutical, chemical, paper, and leather industries.

Technical Specifications and Performance

The GN Screw Press Dewatering Machine offers a range of models with capacities tailored to various sludge concentrations, from 2000mg/L to 50000mg/L. These capacities allow customization based on the specific needs of each industry or application. Here’s a quick reference for some of our models:

Model	DS Standard Capacity (kg/h)	Capacity for 2000mg/L Sludge (m³/h)	Capacity for 50000mg/L Sludge (m³/h)
GNDL131	4–14	~2	~0.28
GNDL201	8–20	~4	~0.4
GNDL301	20–70	~10	~1.4
GNDL401	67.5–160	~33.7	~3.2
GNDL404	266–640	~133	~12.8

Each model is designed with specific screw diameters and power requirements, ensuring reliable performance and compatibility with different operational needs.

Advantages of the GN Screw Press Dewatering Machine

• Versatility: Suitable for a wide range of sludge dewatering applications, including oily sludge treatment.
• Continuous, Automatic Operation: Designed for easy, continuous operation without clogging, even under demanding conditions.
• Cost-Effective: Low initial investment and operational costs, with no secondary pollution.
• Energy Efficiency: The machine is compact and consumes minimal energy, reducing overall environmental impact.
• Aerobic Dewatering: Sludge dewatering occurs under aerobic conditions, minimizing the release of phosphorus associated with anaerobic dewatering processes.

Functional Design Features

The main filtration unit of the GN Screw Press Sludge Dewatering Machine consists of a series of fixed and moving rings with a screw axis. This layout promotes efficient sludge transportation and ensures minimal clogging, as the rotating screw axis drives the moving rings to continuously clean the filtering gap. Sludge thickening occurs in the front section, while the rear section focuses on dewatering, using a back-pressure plate to generate internal pressure, maximizing dewatering performance.
