Desanders are used to separate sand which is mixed with drilling muds. During drilling process mud is being poured as excavation is getting deeper, this mud also mixes with soil, thus being contaminated with sand and silt, in such a way, that when excavation is finished, it is necessary to recycle mud in order to separate sand from mud and get a clean mud that will be used in next excavations. Each country establishes its own regulations on maximum allowed sand content in drilling mud before concreting operation is carried out, in order to prevent concrete contamination with sand and soil, and Desanders are used for this purpose.
A desilter is used to separate silts from drilling muds. The cut point can be as low as 7-10 μm. As muds are being used in drilling operations, they are contaminated with silts. In order to use again these muds, it is necessary to separate silts and also to recycle muds to dispose them at the end of work duty.
Mud cleaner is the combination of desander and desilter.
Brightway offers a line of mud cleaners that employs a two-stage separation process for the ultimate in drilling fluid recovery. Our mud cleaners use a combination of hydrocyclones mounted over a shale shaker to operate as a single unit.
Brightway mud cleaners are designed to handle the entire circulating volume to remove and dry solids while retaining premium base fluid. They are equally effective for both weighted and unweighted drilling-fluids.
With our mud cleaners, the hydrocyclones make the primary separation with underflow directed onto the shaker vibrating screen. Brightway mud cleaners have been proved effective in lowering both drilling-fluid and disposal costs.
