GNLW553C-VFD decanter centrifuge is a big bowl big treating capacity decanter centrifuge which is designed and produced by GN solids control. It has been applied for various industries, for example drilling waste management system, dredging slurry separation system, dewatering unit for TBM waste water treatment, industry waste water treatment, mining tails treatment, oil sludge waste treatment, even solids control system. It is the biggest model we have right now, drived by VFD control panel, the bowl size is 22inch bowl diameter by 71 inch bowl length.

GNLW453C-VFD decanter centrifuge is also big bowl centrifuge with 18inch bowl diameter and 60 inch bowl length.

GNLW553C-VFD decanter centrifuge for dredging slurry separation:

With dewatering unit, GNLW553C-VFD decanter centrifuge can be used to separate the dredging slurry and get relatively clear water, which could be drain off to the river/lake. Firstly we use mechanical way to separate big solids, big cuttings, solid trash, and have the clean fluids storage into the mud tank. After treatment by 4 inch desilter cone, over 80% of the particles bigger than 25 microns has been separated out. The discharge solids/trash will be shipped out by truck. The clean fluids will be added polymer and separated by decanter centrifuge, then you will get relatively dry solids with water content 50% and clear water will be storage by another tank and drain off to the river.

One of the disadvantaged by this design is the treating capacity of the dewatering unit with centrifuge is not big enough, so you need to stop the first mechanical separation part( shale shaker, desander, desilter) for a while to let the centrifuge treat the remained water sufficiently. Then start the shale shaker again. But compared with the traditional belt press, the treating capacity is much bigger, and it is with less power consumption.
