GN Company Decanter Centrifuge for European Client

Client from Europe orders one unit of 2-Phase Decanter Centrifuge from GN Company, which is used for dewatering clarifier sludge. This project needs all the wetted parts of decanter centrifuge to be duplex stainless steel 2205, because of high content of chloride in the sludge.

2-Phase Decanter Centrifuge is used for solid liquid separation, and it can be widely used for environmental protection, drilling mud treatment, oily sludge treatment, sand washing water treatment, beverage clarifying, etc. For environmental protection, Decanter Centrifuge is mainly used for sludge dewatering. GN Company is capable to manufacture decanter centrifuge with bowl diameter from 220mm~760mm, and capacity 1m3/hour to 120m3/hour.

GN Company is capable to supply the Decanter with ATEX and IEC explosion proof standard, including Motor and Electrical Control Cabinet. All the electrical parts can be reputable International brand, and clients find easily in local market for spare parts.

The wetted parts of GN Decanter Centrifuge can be Duplex Stainless Steel 2205, and Stainless Steel 304/316. For project with high content of salt or chloride in the sludge, GN Company Engineers suggest Duplex Stainless Steel 2205, which has better performance of anti-corrosion.

For better wear resistance, the Screw, solids port, and distribution port are all protected by tungsten carbide plates.

Besides supplying single unit dewatering equipment, GN Company is also capable to manufacture and supply supporting equipment, such as Polymer Preparation Unit, Sludge Feeding Pump (progressive cavity pump), and Screw Conveyor, etc.

Welcome to contact GN Sales Managers, and they would offer one stop turnkey solution based on clients’ project.

HDD Mud Dewatering Decanter Centrifuge for Sinopec Project

GN Company supplied one complete set of Decanter Centrifuge for Sinopec, which is used for their HDD mud treatment project. Now GN Company received great feedback from client, for the reliable performance and high quality of GN Decanter in actual work.

For HDD mud treatment project, generally the mud firstly comes to Vibrating Screen, where coarse particle would be separated out, and normally it is more than 100um. Then the mud would be fed into Decanter Centrifuge for separating out fine solids, especially for 2~5 um fine solids. Then the clean mud can be reused for HDD drilling project.

Decanter Centrifuge achieves solid liquid separation by Centrifugal force. When the mud is fed into Decanter Centrifuge, because of the difference of specific gravity of Solid and Liquid, there would become solid layer and liquid layer, with high rotation speed of Bowl. And the solid would be pushed out from the solids discharge outlet, and liquid phase would be discharge from the other side outlet.

Considering the high content of solids, there would be tungsten carbide tiles installed on the screw and discharge port, and it would greatly increase working life of decanter. And the tiles are replaceable.
In order to get better performance of removing fine solids from liquid by Decanter Centrifuge, generally there would be a Polymer Preparation Unit, which is used for dosing flocculent.

Besides supplying main dewatering equipment, GN Company can also supply Sludge Feeding Pump, Screw Conveyor, etc.

Welcome to contact GN Sales Manager, and they would offer One Stop Turnkey Solution for clients’ project.

GN Company Supplied Decanter Centrifuge for European Client

Client from Europe ordered one unit of Decanter Centrifuge for their refinery plant, used for oily wastewater dewatering.

Before this European client thought our Decanter’s bowl speed and centrifuge force are lower, when compared with European manufacturers. It is fact that Bowl Speed and g-force are important factor for dewatering capacity of Decanter. But that is not to say that dewatering capacity would increase as bowl speed increases, because capacity has limited value considering certain bowl size of decanter. Based on GN Company’s Engineers’ experience, 3400~3800 RPM is the optimal speed for this size of Decanter (bowl size 360mm). If the speed passes 3800rpm, the dewatering capacity would not increase. And at higher speed, the screw of decanter would suffer greater resistance to discharge sludge, and become more quickly to get abrasion. Therefor higher speed reduces the working hours/life of Decanter. Above all, GN Technical Team suggests it’s best to keep the Decanter within the range of its optimal speed.

GN Company’s Decanter Centrifuge’s speed can be adjustable through VFD in the control cabinet.
The presence of sediments in the liquid phase after treatment by GN Company Decanter is that Sediments in the liquid phase would not be recognized by eyes.

And GN Company Decanters’ both Vibration Protection and Bearing Temperature Protection are available and optional, and it can added based on clients’ requirement.

GN Company can also offer Main Motor Failure Alarm (including overload, current/torque, under-voltage, etc.), Back Motor Failure Alarm (including overload, current/torque, under-voltage, etc.), and Sludge Feeding Pump Failure Alarm.

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