GN Separation is proud to announce the successful delivery of our Dewatering Centrifuge System to an overseas client. This system includes our high-performance GNLW series Decanter Centrifuge and the GNSJY2000 Chemical Dosing Unit, designed to meet the demanding requirements of wastewater treatment and sludge dewatering applications.
GN Dewatering System: Effective Solution for Fine Particle Separation
In many wastewater treatment processes, simple mechanical separation methods can only remove particles in the range of 2–5 microns. However, ultrafine particles, often present in industrial wastewater, are much more difficult to remove using traditional methods.
GN’s Dewatering System provides an efficient solution by combining a high-speed Decanter Centrifuge with a Chemical Dosing Unit. With this integrated system, ultrafine particles can be flocculated into larger, more easily separable clusters, enabling the centrifuge to achieve optimal separation performance and meet the client’s discharge or reuse requirements.
GNSJY2000 Chemical Dosing Unit: Precision and Efficiency
The GN Chemical Dosing Unit is a compact, easy-to-operate, and low-energy consumption system designed for the automatic preparation and dosing of flocculants. It is widely used in sludge dewatering, solid-liquid separation, and various water treatment processes. The dosing compartment allows for stirring, dissolving, and storage of flocculants, which are then delivered to each dosing point by dosing pumps.
To meet various project needs, GN Separation offers two standard types of Chemical Dosing Units:
1. GN Fully Automatic Dry Powder Dosing Unit (PAM Type)
Configuration Highlights:
| No. | Description | Qty |
|---|---|---|
| 1 | Three-compartment stainless steel cabinet with dry powder hopper, conveyor, flow meter, mixer | 1 Set |
| 2 | Dosing Pump (with bracket and manifold) | 2 Units |
| 3–7 | Safety valves, back pressure valves, pressure gauges, buffer, filter | Complete |
| 8 | Explosion-proof control cabinet with PLC | 1 Set |
Working Principle:
The unit features a three-stage process:
-
Preparation Stage – Chemical powder is fed and mixed with water.
-
Curing Stage – The solution is further dissolved and cured.
-
Storage Stage – The final solution is stored and pumped to the dosing point.
Key Features:
-
Fully automatic with PLC control
-
Compact design and small footprint
-
Easy installation – only water and power connections required
-
Corrosion-resistant materials
-
Consistent performance with intelligent dry powder dosing adjustment
2. GN Liquid Flocculant Dosing Unit
Configuration Highlights:
| No. | Description | Qty |
|---|---|---|
| 1 | PE or stainless steel mixing tank with stirrer and level gauge | 1 Set |
| 2–7 | Dosing pump, safety/back pressure valves, pressure gauges, filter, buffer | Complete |
| 8 | Explosion-proof control cabinet | 1 Set |
Working Principle:
This unit is ideal for pre-prepared liquid flocculants. Operators can either directly pump pre-mixed solutions or prepare solutions manually by mixing powder and water in the tank. The electric mixer ensures even blending and stable flow.
Key Features:
-
Large solution tank volume and energy-saving operation
-
Modular design with small footprint
-
Easy operation and remote control capability via PLC
-
High dosing capacity and stable performance
Containerized Dosing System – Plug & Play Convenience
GN also provides containerized dosing units that integrate the chemical dosing system into a prefabricated container. This layout simplifies on-site installation and enhances mobility, especially in harsh outdoor environments. Operators can work inside the container with all equipment and control panels protected from the elements.
Additional Applications of GN Chemical Dosing Units
GN Chemical Dosing Units are not limited to flocculants. They are also suitable for:
-
Adding coagulants, filter aids, disinfectants, and pH regulators in water treatment
-
Dosing corrosion and scale inhibitors in cooling and circulation systems
-
Chemical dosing in industries such as textile dyeing, printing, and manufacturing
Conclusion
With reliable performance, automation, and customizable design, GN’s Dewatering System continues to be a trusted choice for clients worldwide. Whether for municipal or industrial wastewater treatment, GN Separation’s equipment helps customers achieve efficient and compliant solids-liquid separation.
GN Separation looks forward to working with you on your next project.
