Decanter centrifuge is one of the most popular machines for separation in different industries and for a wide range of applications. The sludge treatment is one of them. In the modern life, there are many kinds of sludge, most of them are damage for the environment. That’s why it is not only necessary but also a must to treat the sludge before discharge. Decanter centrifuge is one of the most important step during sludge separation.

1.What is a Decanter centrifuge: decanter centrifuge is quite efficient in solids and liquid separation, for removing particles from 2 to 5 microns. GNLW554 is a 2 phase centrifuge with a large centrifuge length and diameter ratio, which is suitable for the waste water treatment and sludge treatment. And GN engineer also designed an ideal angle for a better performance.

2.Is it possible to separate the oil and water by the centrifuge? Yes. Besides the 2 phase centrifuge for separating the solids out of liquid, GN Separation also makes the 3 phase centrifuge for separating the solids, water and oil. And according to the clients’ requests, GN also have a disc stack for this similar purpose. Given detailed information about the material, GN engineer will help to recommend most suitable solution.

3.What shall we do if the solids are too fine for centrifuge? Here a flocculating unit is in need to add some polymer into the material. Then the solids particles will be large enough for the centrifuge to choose out. And for the water treatment, GN also have screw press as another popular option.
