Drilling Fluid Dewatering System

In zero discharge situations, The Drilling fluid dewatering system plays an important role in closed-loop systems. Dewatering unit can remove almost all colloidal particles,producting nearly clear water by using chemical treatment,a manifold system and a decanter centrifuge. Dewatering system can significantly reduce water-hauling,drilling fluid, and disposal cost by recycling of the fluid phase.

Colloidal-size particles build up in the drilling fluid system,require dilution which can create excessive fluid volumes. These ultra-fine particles,less than 5 to 7 microns in size, can not be removed via decanter centrifuge alone.The excess waste volumes created by dilution increased the drilling costs and increase environmental liability.

A complete drilling fluid dewatering system usually consisted of some tanks,like Mix tank, Coagulant tank, Manifold system, Metering system,dosing system, feed pump,centrifuge.

Dewatering Process:

Decanter Centrifuge

1) Dilution
If needed, dilution water is added. some fluids have extremely high concentrations of fine solids and need more free water for proper treatment.

2)Coagulation
by adding coagulants to reduce the electrostatic charge of the particles and enable them to stick or bond together when they make contact with each other.

3)Flocculation
By adding special polymer flocculant to the coagulated fluid. The polymer forms bridges between the coagulated particles,enabling them to physically bond together into larger particles.

4)Centrifugation
The final step in the dewatering process is the removal of the flocculated solids with a high speed decanter centrifuge to generate clear water.
