Drilling waste management is one of the core system GN Solids Control produces, it includes the drilling cuttings separation and also the drilling fluids separation. Dewatering unit, which is also called chemical dosing unit is one of the important components of the drilling fluid treatment systems.

In some countries and regions, it is a must that a drilling rig must be accompanied with a dewatering unit and a dewatering centrifuge, for one thing, more drilling mud could be recycled, which means to reduce the cost and save money. For another thing, it is reducing the harmful components to be discharged to the soil or environment, it helps to protect the surroundings.

GN Solids Control has been providing the dewatering unit for many years, and the dewatering unit now are more and more widely used for different applications, such as:

1. Oil and gas drilling fluids separation. After being used for a certain time, there are more and more extra fine particles in the drilling fluids, even too fine to be separated out by a centrifuge. By adding some chemicals into the fluid, the extra fine particles flocculate into bigger ones to be separated out by centrifuge.

2. In TBM, Piling and other projects, when the slurry is of higher viscosity or need to be added with some chemicals, the dewatering unit is playing an important role, just as shown in the picture, the treatment was successful.

3. In oily sludge separation projects, the added chemicals helps to separate the oil from the cuttings, which greatly increase the efficiency of centrifuge and oil water separator.

GNLW Series decanter centrifuge, especially GNLW363G-VFD, GNLW553-VFD centrifuges are always ideal choice for working together with dewatering unit. Besides those models, GN also has centrifuges with bigger length-diameter ratio for clearer separation.
