During drilling operation, the OBM drilling cuttings need to be collected
and treated at the same time. Because of the contamination to the soil, OBM
cuttings cannot drop to ground. The OBM cuttings can be collected by screw
conveyors, and further dried by vertical cutting dryer; more drilling fluids
can be recovered and pump back to active tank system. We normally call it
on-line treatment system to OBM cuttings.
For spent water-based mud, it normally will be drop into the mud pit for storage. The Chinese government began to require contractors to deal with spent WBM several years ago. With the emergence of more environmental problems, more countries in the World put regulations in the treatment of spent WBM.
Based on our former experience in China domestic market, KES Separation
Design filter press system with dosing unit to achieve a bigger treating
capacity; the working performance has been verified and the user can get dry
solids mud cake and clean water.
The main equipment list included as follow:
| SN | Product | Application |
| 1 | Submersible slurry pump | used to transfer the spent WBM from mud pit to our system |
| 2 | Dosing and mixing tank system | used for flocculation and mixing with spent WBM |
| 3 | Dosing unit skid | 2 or 3 sets dosing unit for PAC or PAM flocculation |
| 4 | Cleaning water collection tank | used to collect the water discharge from filter press; also working to supply water to the dosing tank system |
| 5 | Plate and frame filter press | to final treatment the spent WBM after coagulation and flocculation The user can get dry mud cake and clean water |
| 6 | Remarks | We can suggest on the specific workflow and dosing ratio per request. |
