dewatering centrifuge

GN Company is a professional manufacturer of Decanter Centrifuge from China mainland, with all three factories in China Mainland, and 2 branches in Moscow and Houston separately.

Decanter Centrifuge is one of the main equipment used for sludge dewatering in the wastewater treatment industry. And discharged cake has moisture about 70~75%, which is acceptable for most of job sites discharge requirement. Generally Flocculent can help Decanter Centrifuge to get better dewatering performance. (Decanter Centrifuge is only used to reduce the sludge volume, while there is not any chemical reaction during the dewatering process)

There are 3 VFDs in the control cabinet of GN Decanter Centrifuge’s, which is used for control of Main Motor, Back-up Motor, and Feeding Pump. GN Technical Team can supply both Non Explosion proof Panel and Explosion proof panel, and can reach the requirement of ATEX and IEC standard.

GN Company had already supplied Decanter Centrifuge to USA, Canada, Brazil, Argentina, UK, Russia, Germany, Poland, Nigeria, Egypt, Algeria, UAE, Oman, India, Singapore, Malaysia, etc. And GN Company can offer local service support in Europe and Africa.

GN Company would supply product quality with 18 months after commission and 24 months after factory shipment whichever coming firstly. And GN Company can also send out engineers to clients’ job sites based on their requirement.

GN Company is also capable to manufacture related supporting equipment, including Polymer Preparation Unit, Sludge Feeding Pump, Screw Conveyor, etc.

Welcome to contact GN Sales Managers, and we would offer One Stop Turnkey Solution based on clients’ specific requirement.

GN Company delivered one set of Polymer Dosing System for client from Africa, which is used to help Centrifuge to get better performance during dewatering. Because during sludge dewatering process, the ultrafine solids (less than 2um) cannot be separated by Centrifuge directly.

The Polymer Dosing System is help to gather the fine solids together, and form flocculent, which is easier to be by separated by Decanter.

Besides automatic PAM Polymer Dosing Unit, GN Company can also supply single barrel type chemical solution preparation unit.

GN Company is a professional manufacturer of Separation & Conveying System for 13 years, including Decanter Centrifuge, Disc Separator, Oil Water Separator, Polymer Dosing System, Screw Conveyor, Sludge Solids Transfer Pump, etc.

Here are two Advantages about GN Company as follow,

1. Besides supplying single unit of Equipment,
GN Company takes more advantages of delivering customized One Stop Turnkey Solution for your project, including Design & Manufacturing.
Our Main Equipment is Centrifuge, and we also manufacture related accessories, including Shaker, Pump, Screw Conveyor, Chemical Dosing Unit, Slurry Tank, etc.
2. GN Company can design & manufacture the whole system in Containerization or Skid, it is safety, and easier for transportation by truck, and movable around different job sites.

Welcome to contact GN Company Sales Managers, and they would send professional solution for your project.

GN Company is a professional manufacturer of Decanter Centrifuge, with capability of manufacturing Centrifuge with bowl diameter of 220mm~760mm, capacity of from 1~2m3/hour to 120m3/hour. GN Technical Team is a very professional team, with experience of R&D for more than 10 years.

Here are introduction about Constant Torque self-adaptation Function for GN Decanter Centrifuge.

When concentration changes, the current of back motor (for driving screw) would fluctuate accordingly.

1. When the monitored current value of back motor exceeds set value, the differential speed of centrifuge is too low, the control-programming program automatically controls the back motor working current to decrease to the preset value, and increases the differential speed of centrifuge.

2. When the monitored current value of back motor returns to normal setting value range, the control-programming program automatically controls the auxiliary motor working current to return to the preset value, and the differential speed of centrifuge returns to the normal.

3. When the monitored current value of back motor is low to the set value, the differential speed of centrifuge is too high, the control-programming program automatically controls working current of back motor to rise to the preset value, and reduces the differential speed of centrifuge.

4. Constant Torque self-adaptation Function can ensure the uniform of dry humidity of sludge (discharged from Centrifuge), and avoid the plugging problem caused by concentration change of feeding sludge, which provides reliable guarantee for the normal and stable operation of centrifuge.

For the mixture of large amount of liquid phase and small amount of solid phase, Clarification means to remove the small amount of solid phase from the liquid phase, to make the liquid phase as clean as possible.

(1) Physical Specifications
Clarify the solid phase in the liquid phase, and size, shape, properties of the particles contained in the solid phase, as well as the liquid phase temperature, Ph, viscosity, and specific gravity of the liquid-solid.

(2) Liquid Phase Requirement after Clarification
Solids content in the liquid phase, and moisture content in the solid phase.

(3) Selection of the Centrifuge Model
The big amount of liquid phase has a small amount of solid phase, and the particle size of the solid phase is very small (less than 10 μm) or amorphous mycelium. GN Technical Engineers suggest clients to consider about Decanter Centrifuge, Disc Centrifuge, or Tube Centrifuge. Tube or Disc Manual Slag Discharge Centrifuge can be applicable if the solid phase content is <1% and the particle size is <5µm. If the solid phase content is ≤3% and the particle size is <5µm, Disc Piston Slag Discharge Centrifuge is better. Tube centrifuge has high separation factor (f≥1000), which can separate smaller particles with particle size of about 0.5um, and obtain clear liquid. After separation, the solid residue is closely attached while cannot transfer. It is dry attached to the inside of drum. So the machine needs to be disassembled and cannot be continuously procedured when the dross is removing. And for facilitating the dross removal, some of the drums are lined with a thin plastic paper tube, and the paper tube can be pulled out when the dross is discharged. Disc Centrifuge also has high separation factor (f = 1000). Due to the disc combination, the sedimentation area is large and the sedimentation distance is small. The resulting clear liquid is also good, and the processing capacity is larger than that of the tube centrifuge, but the separation result is that the solid phase produced is also deposited on the inner wall of the drum, and it needs to be dismantled regularly to remove slag, so it cannot be continuously produced.

Welcome to contact GN Sales Managers, and we would find out the best and exact separation solution for your project.
