KES Separation - Spent Water-Based Mud (WBM) Dewatering System

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.

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

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

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

1. With same cost, the treating capacity is bigger. We normally offer 25~30m³/h system;
2. By batch operation, one batch can be 40m³, and it takes about 1.5h to 2hrs to finish the operation;
3. The operation requires professional personnel to operate the dosing unit and filter press;
4. 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.
