KOSUN manufactures solids control systems to separate solids from drilling fluids, enabling fluid recycling. A typical system includes a mud tank, shale shaker, vacuum degasser, desander, desilter, and centrifuge to separate solids by size. KOSUN has produced solids control systems since 1992 for horizontal directional drilling, tunnel boring, mobile, skid-mounted, and arctic applications.

KOSUN Solids Control System
A solids control system is full sets of equipment used together to separate the solids in the drilling
fluids, enabling drilling fluid recycling, it is also called mud purification system.
A solids control system usually includes five stages: mud tank, shale shaker, vacuum degasser,
desander, desilter, and centrifuge. The shale shaker is used to separate big solids with diameter
above 75μm, the desander separates solids from 45‐74μm, and the desilter separates solids
between 15‐44μm. Sometimes the desander and desilter are combined as one high efficiency mud
cleaner. When air enters the drilling fluids, a vacuum degasser is used to separate the air. When
there is no air in the mud, the degasser works as a big agitator. All these stages are mounted on
the top of the mud tank. After separating the solids, the clean mud can be pumped into the
borehole again.
KOSUN solids control system is the best in China since 1992, KOSUN manufacture below solids
control system so far;

2. HDD Mud Recovery System
KOSUN HDD mud recovery system is a standard design type and is divided into the following series
according to different capacities.
TUNNEL BORING MUD SYSTEM (TBM)
The KD Series Separation System is of modular system construction. It is designed for the treatment
of all kinds of slurries used in common construction techniques.

3. Skid‐mounted Solids Control System
The multifunctional design of KOSUN drilling mud System enables the overall system to meet the
requirements of various well depths and drilling fluids.
Mobile Solids Control System
KOSUN has developed drilling mud System, integrating the structural features and design concepts
of the mobile and skid‐mounted solids control system for satisfying the drilling requirements on
time reduction, moving speed improvement and cost trimming.

4. Arctic Solids Control System
KOSUN is able to customize its system to produce the arctic solids control system which is solely
applied under extremely cold temperature to meet the requirements of the polar cold ( minus 40
degrees centigrade ) working conditions.
