GN Solids Control is one of the top Solids Control Equipments manufacturer in the world. We manufacture a complete line of Solids Control Equipments, Such as  Shale Shaker, Mud Cleaner, Degasser,Centrifugal Pump, Decanter Centrifuge,Agitator,etc.  As the development of GN in the past 5 years, Now GN also can provides customized drilling fluid dewatering systems designed to reduce volumes of waste and reducing long term liabilities.dewatering is the process of injecting coagulants or flocculating chemicals into the mud entering a large clarifying centrifuge.

In a minimal discharge, environmentally sensitive area, this mud cannot simply be dumped in a sump and forgotten about.This is where mud dewatering becomes necessary. Also during cement displacements and at the end of the well, dewatering is used when the mud needs to be disposed of.

Dewatering Process:

Drilling Fluid Dewatering System

1) Mud from the active system is pumped into either a separate mud tank or directly into an injection manifold. This mud is tested by the Solids Control engineer immediately prior to processing. Through a series of standard tests, the operator determines the approximate amount and type of chemicals to give an optimum flocculation/ stabilization of the mud.

2)The injection manifold has a series of injection ports and internal static mixers. The calculated amounts of chemicals are metered into the ports with chemical injection pumps. These pumps have variable controls to continuously adjust the amount of chemical injected.
3)The mud which added coagulant and flocculant then goes to a high-speed, high G-force Decanter centrifuge. The Decanter centrifuge separates the flocculated solids from the fluid.

4)The quality control tank allows the unit operator to monitor the effluent from the centrifuge returned to the active mud or storage system. The operator can then make further adjustments to the chemicals and equipment to ensure optimum dewatering. A bypass allows the operator to recirculate the centrifuge effluent if necessary.

5)The neutralizing tank may be used to store dewatered fluid and to make final treatments to the processed fluid, such as pH adjustments, before the fluid is recycled as makeup or dilution water. This tank is partitioned and can be used for prehydrating bentonite, for mixing chemicals, or for storing excess mud.

The heart of GN’s dewatering systems are the polymer conditioning manifolds and high-speed decanter centrifuge. Each manifold is carefully engineered to provide optimum polymer hydration. For more information of GN’s Dewatering System, Please feel free to consult with GN’s engineer
