Wastewater Sludge Decanter Centrifuge
Wastewater Centrifuge/ Sludge Decanter Centrifuge

When you need separate solid /liquid mixtures with high solids content, you can choose a decanter centrifuge.Decanter centrifuges can be optimally adjusted for specific applications. Applications range from sludge dewatering to classification or wet classification to solid classification.

CENTRIFUGE DECANTER ADVANTAGES

• Easy to install and operating equipment
• Small footprint
• Operate for different sludge types
• Operating for thickening or dewatering
• Reduced labour costs
• More process flexibility and higher levels of performance

GN Decanter Centrifuge Function

1)Dewatering sludge / mud and suspensions

2)Thickening sludge or mud

3)Clarifying different type liquids

4)Separating 3-phase mixtures, i.e. two immiscible fluid phases and a solid phase

5) Classifying solids in a wet suspension by grain size

6) Separation of solids according to various densities

The beach angle of the C series clarifying decanter centrifuge is 20 degree, so the bowl cone section is short, and the straight section of the bowl is longer, it will give the bowl to have a longer clarifying section.

The rotating part of these decanter tricanter centrifuges is mounted on a compact, in-line frame, with main bearings at both ends. Vibration dampers are placed under the frame. The rotating part is enclosed in a casing with a cover and a bottom section with integrated outlets for both solids and the liquid being removed.

CENTRIFUGE DECANTER APPLICATIONS

GN recently completed a disc staock separator for oversea clients regarding to vegetable oil processing.

With high running speed and centrifugal separation factor, disc stack separator are often used to separate two immiscible liquid phases with small density contrast, In regards to this project, according to the customer’s requirement, we recommend the max model GNSD225, with a drum diameter 810mm and a pistion diameter of 730mm also the rotation speed is 4500RPM.

Considering the hygiene level of vegetable oil processiong, the material of the bowl ,drum, pistion is made by duplex stainless steel SS2507, in the meanwhile, the disc stack separator equip with VFD control cabinet, (Control cabinet casing material is Stainless steel, equipped with VFD+PLC+HMI Touch screen). As for the control cabinet, it is control by variable frequency drive(ABB), and equip with Siemens PLC and HMI Touch screen. In order to make the overseas know the parameter more easier, we provide English/Chinese interface, you can choose which you need.

The handing capacity is 30-40 m3/h according to your material to process,  and the disc stack separator is equipped with 75KW motors, also with SKF bearings.

For more information on centrifugal separators, please feel free to contact GN Separation at any time.

Since its beginnings, GN has designed, developed and produced different kinds of centrifuges for  solid/liquid and liquid/liquid separation.

GN clarifying decanter centrifuge is C series decanter centrifuge with beach angle of 20 degree. It suits for material of small particle size, low density difference between solids and liquid, moderate viscosity, moderate concentration.
