Product Description

Product Description

Spent WBM Dewatering system is used to treat the spent WBM in the drilling mud pit. After completion of drilling operation, the spent water-based mud in the mud pit needs to be treated according to environmental protection requirement. Normally, we have two options to deal with the spent WBM- by centrifuge and polymer unit or by filter press and polymer unit. Here in this chapter, we will give a general comparison between centrifuge treatment and filter press treatment, the advantages and disadvantages of each solution.
 

1)      Spent WBM dewatering by Polymer unit + Centrifuge

S/N	Product	Short Description
1	3-chamber automatic dosing unit	Used to mixing and aging of Polymers to coagulate the fine solids in the WBM, normally we can use PAC or PAM agent
2	Pipeline with static mixer	The pipeline will link the dosing unit with decanter centrifuge, the aging polymer and waste WBM will be mixed fully in the static mixer, and then feeding to decanter centrifuge
3	Centrifuge Feed Pump	Normally we adopt progressive cavity pump as feeding pump to centrifuge. The spent WBM will be transferred to the static mixer continuously by feed pump, the feeding will be without pulse, stable feeding
4	Decanter Centrifuge	The spent WBM after mixed with polymer will be separated by high-speed decanter centrifuge, it is easy to get clean water from centrifuge; the mud cake moisture normally can be about 40%~50%
5	Mud skip or tanks	Mud Skips or tanks may be required to collect the dry mud discharged from centrifuge
6	Water Tanks	Water tanks may be required to collect the clean water discharged from centrifuge.

The composition parts of centrifuge dewatering unit as above table, Features of Centrifuge dewatering unit as below:

• With same cost, the treating capacity is much smaller compared with filter press dewatering unit
• Continuously non-stop operation, the operation requires professional personnel to operate the dosing unit and centrifuges;
• Centrifuge with polymer unit can be designed into one 40ft container, easy transportation and fast installation

2) Spent WBM dewatering by Polymer unit + Filter Press

S/N	Product	Working Description
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	2 or 3 sets dosing unit for PAC or PAM flocculation
4	Cleaning water collection tank	Cleaning water collection tank; 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

The composition parts of filter press unit as above table, Features of filter press with polymer unit as below:

• With same cost, the treating capacity is bigger. We normally offer 25~30m3/h system
• By batch operation, one batch can be 40m3, and it takes about 1.5h to 2hrs to finish the operation.
• The operation requires professional personnel to operate the dosing unit and filter press;
• The foot print is normally bigger than that of centrifuge unit. But the separation performance is much better, the mud cake can be much drier.
