Recently, a mud cleaning shale shaker, mud cleaner, and decanter centrifuge started to work at an Environmental Protection Company in U.S.A. The Environmental Protection Company in U.S.A. is to collect waste water and waste slurry from different activities, like from drilling, from construction job sites, etc… The company will treat the waste slurry, and cover the water and oil for reuse or resell. The recovered solids, cuttings and particles can be sold again to construction company for building construction, or to build roads.
Below separation equipment in included in the mud cleaning job site for the USA Environmental Protection Company.
The 1st mud cleaning equipment is a Shale Shaker. It is a 4-panel shale shaker utilizing composite material pretension shaker screen. The shale shaker model is GNZS594-HB. It is the most hot sale shale shaker model from GN Solids Control. The shale shaker is widely used in oil and gas drilling, non-oil drilling, and waste slurry separation.
The 2nd stage separation equipment is a 3-in-1 mud cleaner. The mud cleaner model is GNZJ594-2S12N. The 3-in-1 mud cleaner separator is combined of a shale shaker, above the shale shaker, there is a package of desander cone, and a package of desilter cone. The desander and desilter packing are used on top of the under flow shale shaker. The recovered slurry from desander and desilter falls down to the under flow shale shaker, and recovered by the shaker screens which with fine wire mesh. The desander separation is 10 inch which is with cut point 47 microns. The slurry recovered from desander separator will be pumped to desilter separation. The cut point of desilter separator is 27 microns, which is used to further purify the recovered slurry. After desilter separator, the weight of the slurry can be reduced, the solids content is smaller. And the solids size in the slurry is qualified for high speed decanter centrifuge separation.
A high speed big bowl decanter centrifuge GNLW553-VFD is used after mud cleaner separator to remove the ultrafine solids up to 2 microns.
