This week, GN arranged to ship out a set of decanter centrifuge.

This model of centrifuge come with a bowl diameter of 220 mm and a bowl L/D ratio of 4.2, which allows the material to be processed to remain inside the equipment for a longer time, which increases the separation time. When evaluating the performance of decanter centrifuge the rorating speed and separation factor are important indicators, The Max rotating speed of this GNLW224 can achieve is 4500RPM, with a separation factor of 2500, high operating speed and separation factors can enable better stratification of the solid liquid two phases within the bowl.

At present, the max model of 2 phase decanter centrifuge we can produce is GNLW764, The Max rotating speed of this GNLW764 can achieve is 2650RPM, with a separation factor of 2988,  According to the processing capacity requirements and budget, customers can choose different models for corresponding applications. Typical applications include municipal sludge dewatering, tail sludge dewatering, industrial inorganic salt crystal dewatering, and so on.

The IE Expo in Shanghai was successful conclusion. GN team received a lot of customer and potential customer, and explain different efficiency of the separation equipment base on the diffferent industry.

The theme of this show by GN Company is oily sludge treatment equipment. GN is can not only provide customers with separate equipment, but also provide customers with complete system solutions. At the show, GN showcased the main equipment of various modules of the oil sludge system, including sludge transfer pump, coarse vibration screen, 2-phase decanter centrifuge, and 3-phase disc separator. Below is a brief introduction to GN oily sludge treatment system according to the modules.

According to the customer processing requirement, we can provide 2-phase decanter centrifuge, 3-phase centrifuge and 3-phase disc stack separtor for your choose,  The ultimate goal is to achieve three-phase separation of oil, water, and solid residue.

 

IE expo China is Asia’s leading environmental expo which offers an effective business and networking platform for environmental sector and is accompanied by first-class technical-scientific conference program. GN separation will attend this expo in 19th April-21th April 2023 and show there equipment for oil sludge treatment and solid liquid separation.

Below information that will help you to locate GN booth.
Event Name: IE expo China 2023
Location: Shanghai New International Expo Centre (SNIEC)
Expo Date：April 19~21, 2023
GN Booth: N4-H46 (Hall 4)

The equipment to be exhibited by GN separation can you applied to solid liquid separation, herwith pls find the details as below

sludge vacuum pump is absolutely pneumatic driving pump suitable for multi-material transferring. No matter low solids content or high solid contend materials like waster, low viscosity slurry, thick sludge and even solid powder can be transferred by GN solids vacuum pump. Depends on the model and jobsite a condition, the pump is supplied with manually operation and automatic operation method. With sufficient air pressure and air flow, the pump can work continuously.

 

Sludge Dewatering Centrifuge – GN decanter centrifuge is widely use solid liquid separation equipment, it can do solid-liquid-liquid separation and solid liquid separation.

If you have any question on separation solution, welcome to GN booth, GN Separation is looking forward to seeing you at Expo.

 

Currently, GN disc stack centrifuges is widely used for algae filed, there are a heavy demand in Europe and all of the world. The principle is that the algae suspension is fed directly into the centrifuge, inside centrifuge the suspension is separated into a mostly clear water phase and an algae concentrate, the algae concentrate is discharged periodically and has a fluid/creamy consistency.

The disc stack centrifuge  can treat the particles content less than 3%, it’s better to be 0.2%. Therefore, in some application, pre-treatment will be carried out by dissolved air flotation device, and then clarification and separation will be carried out in the disc stack centrifuge. And this disc stack centrifuge is specilize on algae.

Kindly check the test as below

The algae water mixture of 2% solids content, We will centrifuge this mixture to produce an algae concentrate of minimum 20% solids. The algae/water mixture fed to disc stack centriuge will originate from a DAF (dissolved air flotation device) meaning the algae will have been flocculated.

Concentration of algae solids in feed at 0.1%,   90% of the algae present reports to the concentrate.
