Last week, several packages of Mud Cleaning System were shipped to Chinese sea port. The mud cleaning systems will be sailed to North America to service their mud cleaning projects. The project the client will do is that, they collect various kinds of waste mud and waste water from rigs or from construction field. The client transports the waste mud and waste water by vacuum trucks, and treat them together to reduce the waste material, and recover solids and waste for reuse. It is high standard mud cleaning system to suit for North America standard.
The features of the mud cleaning system are that, its design is very compact for small foot print. Several mud separation shale shakers and dewatering centrifuge unit are equipped in the system for better separation performance.
1) First separation is by double deck coarse shale shaker to remove the big size solids from the waste mud and waste water. The top of the shale shaker is covered by metal boards to avoid mud leakage during shale shaker vibration.
2) After the double deck coarse shale shaker, next separation is taken by a single deck high G force shale shaker. The same design as the double deck shale shaker, the top of the single deck shale shaker is covered by metal boards to avoid mud leakage during shale shaker vibration.
3) A package of dewatering centrifuge unit.
As there are still many fine solids particles inside the recovered water from shale shakers, a dewater unit is used in the system for chemical dosing. It is used together with a high speed big bowl decanter centrifuge for fine solids separation.
The mud cleaning systems can recovery as more sands from the waste water. Regarding the waste mud from hydraulic excavation drilling, the recovery liquid phase is usable mud for reuse. The separated sands can be used for construction material.
