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 dropped 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.
| 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 discharged from filter press; also working to supply water to the dosing tank system |
| 5 | Plate and frame filter press | to finally treat 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. |
