Solid control function in oil and gas drilling mud cleaning system

A typical drilling mud solids control system will employ a combination of shaker, hydrocyclone, mixing, pump and compartmentalized tank technologies. The shaker is vital to the solids control system and is considered the first line of defense.  Located directly downstream from the shaker will likely be a hydrocyclone assembly that will employ desilters, desanders or both. Though still considered rare, centrifuge-enable solids control systems are becoming more popular.  By adding a centrifuge, the solids control system will achieve the highest level of cut available within the market today.
