At GN SEPARATION, we take pride in our new solutions for industrial waste management. One of our flagship products, the GN Solids Vacuum Pump, also known as the sludge vacuum pump, is an innovation in the field of solids transfer. This vacuum loading solids transfer pump is fully powered by compressed air, making it an efficient and reliable solution for transferring solids, powder, slurry, and sludge.

What Makes GN Solids Vacuum Pump Stand Out?

The GN Solids Vacuum Pump is designed to be compact, robust, and incredibly efficient. It utilizes a powerful vacuum of 25″ hg to load materials and is capable of delivering them over distances of up to 500 meters. Available in three different capacities (10 m3/h, 20 m3/h, and 40 m3/h), these pumps can also be customized as Group Pump Units on a single skid, offering versatile and scalable solutions for various industrial needs.

Key Applications

The versatility of the GN Solids Vacuum Pump makes it suitable for a wide range of applications, including:

• Thickener De-sludge: Efficiently removes sludge from thickeners.

• Mining Slurries and Offal Transfer: Moves mining slurries and waste materials.
• Bulk Transfer: Handles bulk transfer operations, both loading and unloading.

Working Principle of the GN Solids Vacuum Pump

The GN Solids Vacuum Pump operates on a simple yet powerful principle. Compressed air is fed into the pump, creating a high vacuum inside the pump tank. This vacuum draws materials into the tank through the suction line. After a few seconds, the valve changes the air direction to create positive pressure, pushing the material out of the pump tank through the discharge line.

The GNSP-40A, a larger model, offers both manual and automatic modes, while the smaller models, GNSP-10A and GNSP-20A, operate automatically. This pneumatic operation ensures safety and reliability, especially in hazardous environments like the oil, gas, and coal industries, where explosion-proof equipment is essential.

GN Vacuum Cleaner for Industrial Waste

In addition to the GN Solids Vacuum Pump, we offer the GN Mini Vacuum Cleaner, designed for tough industrial clean-up jobs. This mobile and lightweight suction tool is air-operated, producing a high vacuum for efficient suction and can switch to positive pressure for discharge. Operators can set up automatic suction and discharge cycles, enhancing efficiency and ease of use.

Conclusion

The GN Solids Vacuum Pump and GN Mini Vacuum Cleaner are at the forefront of industrial waste management technology. Their robust design, efficient operation, and versatility make them invaluable tools for a wide range of applications. At GN SEPARATION, we are committed to providing innovative solutions that meet the evolving needs of our clients.

At GN Separation, we are dedicated to providing solutions for liquid and solids separation. One of our flagship products, the Slant Plate Clarifier, also known as the inclined plate clarifier, exemplifies our commitment to innovation and efficiency in wastewater treatment.

What is a Slant Plate Clarifier?

The Slant Plate Clarifier is a type of liquid and solids separation equipment. It functions by allowing a mixture of solids and liquid, sometimes pre-flocculated, to enter through a trough into the clarifier. As the mixture flows upward between a series of slant plates, the solids settle onto the plate surfaces and slide down by gravity into a sludge collection hopper. The clarified liquid then flows through orifice holes and exits at the top of the clarifier.

Advantages of the Slant Plate Clarifier

Compared to traditional settling tanks, the Slant Plate Clarifier offers significant advantages:

• Cost-Effectiveness: The design and operational efficiency of the Slant Plate Clarifier make it a more cost-effective solution.
• Small Footprint: The slant plates provide a large effective settling area within a compact space, making it ideal for facilities with limited space.
• Energy Efficiency: It requires less energy to operate compared to decanter centrifuges, contributing to lower operational costs.
• Ease of Maintenance: With minimal moving parts, the Slant Plate Clarifier is easy to maintain, reducing downtime and maintenance costs.

We are thrilled to announce that GN Separation has successfully sold two units of our screw press sludge dewatering machines, model GNDL402, to a European client. These machines represent the cutting edge of economic and environmentally friendly sludge dewatering technology.

The GN Screw Press: An Overview

The GN screw press sludge dewatering machine is designed to be both cost-effective and environmentally friendly. It utilizes the principle of screw extrusion to achieve solid-liquid separation. This process is driven by the powerful squeezing force generated through the variation in screw diameter and pitch, along with the minute gaps between the floating and fixed rings. This innovative design ensures efficient dewatering by leveraging mechanical principles for superior results.

Key Features of the GN Screw Press

• Economic and Environmental Benefits: The GN screw press is engineered for minimal environmental impact and operational cost, making it an ideal choice for sustainable operations.
• Advanced Dewatering Technology: By using screw extrusion, the machine provides robust dewatering through changing screw diameters, screw pitches, and gaps between rings, ensuring effective solid-liquid separation.
• Automatic Control: Equipped with a fully automatic control cabinet, flocculation modulation box, sludge thickening and dewatering device, and liquid collecting tank, the GN screw press allows for continuous and automatic operation.
• Versatility: It is suitable for a wide range of sludge dewatering applications, including oily sludge treatment. The machine is designed to operate continuously and automatically without clogging.

ADVANTAGES OF THE GN SCREW PRESS DEWATERING MACHINE

1. Wide Application Range: Suitable for various industries such as municipal sewage treatment, aquaculture, food processing, starch production, oil refining, pharmaceuticals, chemicals, paper production, and leather manufacturing.
2. Continuous and Automatic Operation: Ensures consistent performance with minimal manual intervention and reduced risk of blockages.
3. Cost Efficiency: Low investment and operational costs combined with no secondary pollution make it a financially sound choice.
4. Energy Efficiency: Compact design and small footprint contribute to energy savings and environmental protection.
5. Enhanced Sludge Treatment: Capable of dewatering sludge under aerobic conditions to prevent phosphorus release from anaerobic sludge dewatering.

Technical Details

The main body of the GN screw press dewatering machine consists of a filtration device composed of fixed and moving rings, with a screw axis running through them. The front section of the machine is dedicated to concentration, while the back section focuses on dewatering. As sludge progresses from the concentration section to the dewatering section, the filtering gap and screw pitch gradually decrease, enhancing the dewatering effect.

The rotating screw shaft not only transports the sludge but also drives the moving ring to clean the filtering gap, preventing clogging and ensuring continuous operation. This design enables effective dewatering by generating high internal pressure as the sludge volume is reduced.

Application and Customization

The GN dewatering screw press can handle sludge concentrations ranging from 2000 mg/L to 50000 mg/L. We offer a comprehensive range of sludge dewatering equipment, allowing clients to select the best solution based on their specific sewage treatment needs and budget. Additionally, GN provides integrated mobile sludge dewatering solutions tailored to customer requirements.
