Hydrocyclone desander desilter is the solids control equipment, Desander is the second phase solids control equipment for separation sands, desilter is for drilling mud silts separation. GN desander desitler have many options from Mini desander desilter to mud cleaner.Desander desilters are widely used in oilfield drilling, bored pile drilling, CBM Drilling and HDD.

Part II: Desander & Desilter Plant for Bored Pile

Bored piles are cast in place cylindrical piles excavated either by use of rotary equipment operated augers , buckets, under static drilling fluid or large drill bit (for hard rock) with reverse circulation.The reason to use desander unit is that Bored piles installed in common soil with the presence of water table, generally require the use of a short temporary steel casing and a drilling fluid as static suspension to provide support to the surrounding soil while excavating the pile and until complete backfill of the pile excavation with concrete, in order to prevent cave-in of the excavation and destabilizing the surrounding soil formation.GN Bored Pile Desilter desander is to separate the sands from the drilling fluids and recycling the drilling fluids for use.
