Skid mounted Drilling Fluids Purification Unit ready for delivery

In solids control and drilling waste management system, the operators focus more on the solids parts treatment, eg. Solids discharged from shale shaker, mud cleaner and centrifuge. The solids can be further treated by vertical cutting dryer or High G shale shaker, and finally the dry solids will be transported to Thermal Desorption Unit for final treatment and reach the standard of environmental protection. But how about the drilling fluids after drilling completed? As the drilling fluids contains many different chemicals, definitely it will affect the surroundings and environment if disposed without treatment.

To solve the problem, we are developing drilling fluids Purification Unit which can further separate the fine solids from drilling fluids and make the water very clean to reach the standard of discharge, without contaminate the soil. Centrifuge and flocculent units system can help to solve this problem in relatively lower cost.

Following are the basic composition of Skid Mounted clarification unit

1)       3-Chamber Flocculent unit

3-Chamber flocculent unit contains chamber for preparation, aging and ready for use. The flocculent units normally is automatically controlled and add the chemical fluids automatically to the drilling fluids, coagulating the ultra-fine solids and immediately feed to high speed centrifuge for separation.

The chemicals can be PAM or PAC, the ratio should base on the technical instructions from mud engineers.

2)       VFD High speed centrifuge

The VFD high speed centrifuges are similar size to Derrick DE1000 Centrifuge or Brandt HS3400 centrifuge. All are 14inch bowl centrifuge with over 3000rpm bowl speed. The centrifuge bowl material are made from Duplex Stainless Steel 2205 or 2304, the scroll material are made from SS316L, the impeller welded on the scroll are protected by carbide alloy tiles or melting technology which is much reliable than carbide alloy. The centrifuge control panel are Ex-proof standard with PLC control; frequency convertor are normally purchased from ABB or Siemens for reliable performance.

Centrifuge feed pump, we normally purchase from Netzsch or Subtor, they are all Germany brand Screw pump with good reputation. This kinds of pump are same type to Mono pump.


The equipment are holding by one each 20ft container frame, can be put into the container cart very convenient for transportation.

Except for drilling fluids purification, the unit can also be used for the slurry purification in pipe jacking project, HDD project, Piling project and TBM projects, River dredging project and sand washing projects.
