Desanders are solid control equipment with a set of hydrocyclones that separate sand and silt from the drilling fluids in drilling rigs. Desander is installed on top of the mud tank following the shale shaker and the degasser, but before the desilter. Desanders remove the abrasive solids from the drilling fluids which couldn’t be removed by shakers. Normally the solids diameter for desander separated would be 45~74μm, and 15~44μm for desilter.
Desander technology is always used in chemical, environmental protection, medicine and food industries widely. Practice has proved that Desander is a kind equipment of economic and effective, the operation is simple needn’t maintain, it is the disposable investment, don’t have energy-intensive and it is environment protecting physics water treatment equipment.
